CHAPTER ONE

INTRODUCTION

1.1. BACKGROUND

It can be attested to the fact that the priority of every government for any developing country is to be able to build up proper infrastructure (Roads, schools, health facilities, water and sanitation facilities, energy facilities, etc) as a backbone for further growth and expansion of the economy.

A quick observation and research has revealed the absence of such a comprehensive database which is represented in a spatial manner to show distribution patterns for quick and easy interpretation which enhances effective decision making. The capacity to take relevant decisions timely and with a bit more precision depends on the availability of such tools to support the making of such decisions.

Geographic information system is an immerging technology whichhas the capability of representing real world situations onto an information system. It deals with actual location of real world object, the shape of the object and other attributes being captured into this information system such that it is astrue as the real world is, at any given time.

With such a tool available and the need for proper decision support tool for identified stakeholders as the government, local authorities, donor agencies, investors etc, it thereforebecomes relevant and necessary to try and use this immerging technology to solve this decision support system gap that exists.

1.2. SCOPE

A brief introduction to the functionalities of the project in terms of what answers decision

makers and other stakeholders would be receiving from the system includes the following;

- How many Primary, JHS and SHS are in a particular area ofinterest

- How are these schools distributed within the area

- What is the facility’s current state and who owns it- Is there the need to put up similar facilities within

the same location.

- Are existing facilities enough for a particular area, etc

8

This is a decision support tool, which will present very relevant information to interested stakeholders to support critical decision making in these areas (Education, Health, Water and Sanitation) of interest, through a GIS web mapping technology.

1.3 TITLE

A DISTRICT BASED ONLINE GEOGRAPHIC INFORMATION SYSTEM FOR HEALTH, EDUCATION, WATER AND SANITATION FACILITIES.

1.4. AIM

As highlighted in the problem statement, there exist a need for such a decision support tool to aid effective decision making in the areas of educational, health, water and sanitation with respect to facilities in these areas.

To develop an online GIS based database on facilities in thevarious sectors with virtual information about location, stateof the facilities and dispersion for decision makers and stakeholders.

1.5. OBJECTIVES

1) To create a spatial database of educational, health and water and sanitation facilities for yendi district.

2) To develop an online mapping application to present detailed information of these sectors in a visually appealing format.

3) Develop geolocation, filter and fetch tools and search identify tools to allow stakeholders perform basic spatial analyses like zoom to a location

of interest, finding out the type and number of schools orhospitals, or clinics or SHS or functioning boreholes etc within an area of interest.

4) Host this information on the web.

5) To provide guidelines to ensure effective maintenance of such database.

1.6. METHODOLOGY

In developing the required system, it has to go through the various software developments

life cycles. The methodologies specifically used in developingthe required system are the

combination of the waterfall and rapid prototyping methodology. The two were selected

because with the waterfall requirements are determined at the early stage of the system

development life cycle. The rapid prototyping ensures that the user gets access to each

phase of the system to check if it meets the specified requirements. The various phases in

developing are explained below;

1.6.1. PLANNING PHASE

This phase involves the initial assessment of the problems with the existing system and

feasibility study. The identified problems were as a result ofstakeholders complaints of

difficulties in having a quick access to a database of the facilities in the community.

Collection of data for this project was done by interview withthe geographical institutions

from time to time.

1.6.2. ANALYSIS PHASE

The existing system is thoroughly reviewed and analyzed to find possible solutions. The

individual components are analyzed to find how they can be improved. Hosting the

database on the internet which represent real world object in a spatial manner and makes

Its accessibility easier was the preferred solution found to solve the problem. Also, user

requirements, existing system evaluation and logical system design was considered.

10

1.6.3. DESIGN PHASE

At this phase, the programming language and platform used, hardware requirement and

software requirement were considered. Below are the details;

Hardware SpecificationProcessor Single 800 MHz or higherRAM 512 MB or higherDisk Storage 100 GB or HigherUPS On-line UPS 650 VA

Software SpecificationOperating system Windows 7Web Server Internet Information ServiceDatabase Server MySQLMap Publisher Map publisher 8.o

Programming language Visual basic.net(VB.NET)

1.6.4. IMPLEMENTATION PHASE

This section involved coding, testing and debugging, installation and finally running. Visual

basic.Net (VB.NET) which provides all the features that are required to develop a graphical

user interface as ready to use components and MYSQL for dynamic database was used.

CHAPTER TWO

LITERATURE REVIEW

2.1. INTRODUCTION

Leveraging technological advancement to equip social issues indeveloping countries has always been difficult for past and present government. It becomes much difficult for government, investors and stakeholders to have a clear knowledge about communities which are not well developed in terms of health, education and proper layout of water and sanitation facilities. Hence my project proposes using geographic information system (GIS) as the framework for decision supporttool for community leaders and more specifically to assist them to prioritize infrastructure maintenance. Geographic information system which is an emerging system thus has the

capability of representing real world situations onto an information system for easy and quick understanding. This paper presents a global “state of practice” GIS for managing the district’s facilities (health, education, water and sanitation) with emphasis on Yendi district.

2.2 BACKGROUND INFORMATION ON GIS

A Geographic Information System (sometimes called geographical information systems) or GIS can be described as general purpose computer based technique for handling geographic data in digital form in order to capture, store, manipulate, analyze, manage and display diverse sets of spatial or geo-referenced data . ( Peter. A. 1998. Principles of geographical information systems ., http://ukcatalogue.oup.com/product , 21st February,2012.)

In essence, GIS relates database records and their associatedattributes data to a physical location, thereby creating a “small map”. Visualization of discrete parts of these data on a GIS applications can then display the intersection of various “themes” as well as the spatial relationships between various features .( Vanier D.J. “GIS” as an integrated decision support for municipal asset management., www.nrc-cnrc.gc.ca/obj. 4th February,2012.)

GIS are spatial database of digital maps which store information on various phenomena and their locations. GIS makes it possible to know the exact locations of real world objects and its features through its representation on map or some more sophisticated devices like the GPS.

12

2.3. Overview of an information system

An information system can be defined as an asset of procedure that collects (retrieve) process, store and disseminate information to support decision making and control.(laudon.1998.ManagementInformationSystem.http://www.kulzick.com/stu/typesys.htm. 10th February 2012.)

An information system is an organized combination of people, hardware, software, communication networks and a data resourcethat collects, transform, and disseminate information in an organization.

Both definitions express the need for an input, process and output for information systems to be complete. An information system incorporates technology but is also concerned with information and organizational activities.

2.3.1 Components of an information system

Information Systems consists of components that work together to achieve the objectives of providing information.

People: They are the most important element in a computer based information system. Information personnel are the peoplewho manage, run, program and maintain the system. The people also include the users of the information system.

Procedures: These include the strategies, policies, methods and rules for using the system. These procedures describe whenprogram is executed.

Hardware: Consist of computer equipments that are used to perform input, processing and output of information. Input devices include keyboard, scanners, mouse etc. Processing devices are CPU and main memory. Some output devices are printers and computer screens.

Database: They are organized collection of facts and information consisting of two or more related data fields.

Network: This enables electronic transmission of signals for communication, which enables an organization to carry out their processes and tasks through effective computer network.

Software: Consists of computer programs that drive the operation of the computer. These programs allow a computer to process information.

13

2.3.2 Information System Application Types

The most common types of information systems used are transaction processing systems, management information systemsand decision support systems. Others include electronic and commerce systems. These categories depend on the level of use of the data.

2.3.3 Decision support system (DSS)

By the 1980s, the dramatic improvements in technology resultedin information systems that were less expensive but more powerful than earlier systems. People at all levels of organizations began using personal computers to do a variety of tasks; they were no longer dependent on IS department for their information needs. So people quickly recognized computersystems could support additional decision making activities.

A decision support system is thus an organized collection of people, procedures, software, database and devices used to support problem specific decision making. The focus of DSS is on decision making effectiveness.

The essential elements of DSS include a collection of models used to support a decision maker or user (model base), a collection of facts and information to assist in decision

making (database, and systems and procedures that help decision makers and other users interact with the DSS.

In addition to DSS that support individual decision making, group decision support systems and executive support systems use the same approach of a DSS. A group support system, also called Group Decision Support System, includes the DSS elements just described and software called groupware, to helpgroups make effective decisions.

2.4 GEOSPATIAL TECHNOLOGIES

2.4.1 Global Positioning systems

GPS is a satellite based positioning systems operated by the US Department of defence. The location of the GPS unit is determined by performing triangular calculations on the location of reference satellites at the time of the reading, and the GPS unit while considering the time lag for the signalto reach the unit. The GPS unit must have a unobstructured view of the sky, a clear line of site to the satellites, and limited cloud cover. Multipath

14

interference, caused by signals bouncing off neighbouring objects, alters signal travel time and reduces the accuracy ofcalculations.

Prior to 2000, GPS accuracy was limited to ± 100 metres because of random timings errors introduced by the US militaryto limit GPS misuse by the adversaries. Today, relatively inexpensive hand-held GPS units are accurate to ± 10 metres depending on the number of reference satellites used,(minimum of four)and their location overhead. Differential GPS or DGPS relies on at least four satellites and a real time connection to a known local reference point; this dramatically increases

accuracy to ± 1 metre. Depending on the type of reference point used the amount of post processing, the duration of observation and the location of satellites, DGPS accuracy can be ± 2 mm horizontally triple that vertically.

2.4.2. Personal Digital Assistance

The popularity of PDAs as they are sometimes called, as business/personal notepads and aide-memories has pushed this tool into specialized data collection. These handheld units greatly reduce the amount of paper needed in the field eliminate potential transcription errors from paper to the corporate database. PDAs can directly interface to GPS (to establish location); can download GIS maps (to sight and geolocate neighboring assets).

2.4.3. Remote sensing

Remote sensing is described as imaging without touching, and within the scope of this paper refers to the use of aircraft or satellites to collect geographic information. A satellite image is often the most practical way to acquire usable geographic information. Although this type imagery will help the identification of buried facilities, it is a good way to identify roads and buildings and can assist in geolocating manholes and catch basins by providing reasonably accurate spatial data. Commercial services supply high resolution, ortho-rectified images with a pixel resolution of 2.5 metres($5000US in 2003) that are suitable for superimposition on and validation of existing GIS maps.

2.5. GIS TOOLS USED

2.5.1 ArcGis-Mymical

It’s used for working with maps and geographic information. Also, is used for creating and using maps; compiling geographic data; analyzing mapped information; sharing and

discovering geographic information; using maps and geographic information in a range of

15

applications and managing geographic information in a database. The system provides infrastructure for making maps and geographic information available throughout a community and openly on web. ESSI is one of the companies and almost anindustry standard providing the GIS market with quite a numberof GIS products. ArcGIS has strong spatial analytical capabilities.

2.5.2 ArcGIS Explorer

is a free GIS viewer that gives you an easy way to explore, visualize, and share GIS information. ArcGIS Explorer adds value to any GIS because it helps you deliver your authoritative data to a broad audience.

With ArcGIS Explorer, you can

Access ready-to-use ArcGIS Online base maps and layers. Fuse your local data with map services to create custom

maps. Add photos, reports, videos, and other information to

your maps. Perform spatial analysis (e.g., visibility, modelling,

proximity search).

2.5.3 Map Publisher

The Map Publisher is the software that pieces together data from several sources to create your maps. It is made by using the workbench in a standard Map Viewer install. The process ofmaking maps is fundamentally the same as using the 3.7 Map Translators; however, it has improvements that now simplify the detailed process of making maps. You can connect to several different databases, import the data, merge the data, and then configure the display and the data.

2.6. Database and Database Management System

A database is a group of related files and a Database Management System (DBMS) is the software designed to create, store and manipulate a database.

2.6.1 Importance of Database and DBMS

1. Elimination of program-to-program dependency: Using DBMS the organization of the information is stored with the information, not the application software.

2. Reducing data redundancy: Because all information is storedin one place (database),

data redundancy is greatly reduced not eliminated together.

16

3. Ensuring data security: It can allow information access to only those people who actually need it.

2.7 Microsoft SQL

Structured Query Language (SQL) is the standard language for interaction with databases.

SQL controls access to your data to ensure that multiple users can work with it

concurrently, to provide fast access and also ensures only authorized users can obtain access.

17

CHAPTER THREE

SYSTEM ANALYSIS

3.1. INTRODUCTION TO THE EXISTING SYSTEM

In case of the existing system, the detailed database for the various facilities could be accessed by those who are very close to the system. The system could only provide raw database without a user friendly interface. In trying to have information about the status, ownership, location and number of a particular facility or facilities in an area, the

appropriate authorities in charge of that specific facility iscontacted to gain access to the database. This system slows developments and in making decisions because it becomes very difficult at times to have access to detailed database for a particular facility. Stakeholders, Government and other interested parties usually finds it time consuming in their attempt to get access to a specific data to enhance or facilitate effective decision making.

Information could be accessed through the following means;

1. People closer to the system accessed the database by running sql queries on their computers. The queries therefore output the requested data in a poor user friendly format.

2. Stakeholders and other users had to contact the appropriate authorities of the various facilities for thedatabase of a particular facility.

3.2. PROBLEMS WITH THE EXISTING SYSTEM

The problems with the existing system that has led to its upgrade are listed below;

1. It retards developments since the database does not give a true picture of the real world objects. It is only raw data that are accessible to the interested party.

2. Having access to a data can be sometimes frustrating and time consuming because of the lengthy process involved in getting the data when one is not closer to the system.

3.3. THE SYSTEM’S COMPONENETS

Flow diagrams: are the first tools for the systems componentsto systems processes, the data store or files used by the processes, any external entities that interact with the systemand the information or data flow.

Data store file: it is the repository of the data and remainsthe data in the system. Processes can retrieve data from a

store or enter data into a store. Symbolically, thin lines parallel to each other and having a unique name represent a data store.

18

Processes: they show what the system does. Each process has one or more data inputs and produces one or more data outputs.In designing processes are symbolised by circles in DATA FLOW DIAGRAMS (DFD). Every process has a unique name and number inserted in the circle that processes in the DFD’s.

External Entities: are outside the system. T hey either use the systems output or simply input data into the system. The designer of the system has no control over the external entities. For eg. The system to be designed, the external entities are symbolically represented by a square or rectangle

KEY

Data Flow

External Entity

3.4. ENTTITY RELATIONSHIP (E-R) ANALYSIS AND MODEL

Entity relationship analysis uses 3 major abstractions to describe data.

Entity

An entity is an object with distinct set of properties that iseasily identified. Entities are the building blocks of a database. An entity is represented using rectangle that

school

contains the name of the entity. Entities may treated as nouns.

Relationships

A relationship is used to establish a link or connection between a pair of logically related entities. It is an association between entities. Separate entities can have relationships with each other.

19

Attributes

An attribute is a property of entity that differentiates the entity from other entities and gives information the entity.

ID

name

status

3.4.1. Types of Relationships

Three types of relationships can exist between entities. Theseare:

1. One- to- one (1:1)

2. One-to-many (1: M)

3. Many-to-many (M: M)

Facility

One-to-one Relationship

Two entities have a One-to-one relationship if for every instance of the first entity, there is only one instance of the second entity. Consider for example a region, for each community there can be only one hospital.

1 M

One-to-Many Relationship

Two entities relate in a one-to-one if for every instance of the first entity, there can be zero, one or several instances of the second entity and for every instance of the second entity, these exactly one instance of the first entity. For example, a region having more schools.

Many-to-Many Relationship

Two entities relate in a many-to-many relationship when every instance of the first entity, thee can be multiple instances of the second entity, and for every instance of the second entity, there can be multiple instances of the first entity.

20

3.4.2. KEYS

Entering data integrity ensures that the data in the database is correct and valid. The various types of keys that have beenidentified are:

PRIMARY KEY

A candidate key that is chosen to identify each row uniquely. It cannot have a NULL value.

CANDIDATE KEY

Community owns Hospital

An attribute or a set of attributes, that uniquely identifies a row.

ALTERNATE KEY

A candidate key that is chosen as a primary key is an alternate key.

COMPOSITE KEY

In certain tables a single attribute cannot be used to identify rows uniquely and a combination of two or more attributes used as primary key. Such keys are called compositekeys.

FOREIGN KEY

When a primary key of one table appears as attribute in another table, it is called the foreign key in second table. Aforeign is also used to relate two tables.

3.5. DATA INTEGRITY

Data integrity falls into the following categories:

Entity Integrity

This ensures that each row can be uniquely identified by an attribute called primary key.

Domain Integrity

It refers to the range of valid entries for a given column. Itensures there are only valid entries in the column.

Referential Integrity

This ensures that for every value of foreign key, there is a matching value of the primary key.

21

3.6. NORMAL FORMS

Normalisation results in the formation of tables that satisfy certain specified constraints and represent certain normal forms. The normal forms are used to ensure that various types of anomalies and inconsistencies are not introduced in the database. Normal forms are table structures with minimum redundancy. Some of the normal forms are explained below;

First Normal Form

A table is said to be in 1NF when each cell of the table contains precisely one value.

Second Normal Form

A table is said to be in 2NF when it is in 1NF and every attribute in the row is functionally dependent upon the whole key, and not just part of the key. The situation can lead to insertion, deletion and updating.

Third Normal Form

A relation is said to be in 2NF when it is in 2NF and every non-key attributes is functionally dependent only on the primary key.

3.7. PROPOSED SYSTEM

The online mapping for facilities would present facility information as it exists in the real world, with its associated attribute information in a very easy and friendly interface. It would make very easy and practical to access such information.

The existing system stops at where data is capture into the database. There is no concrete visual display mechanism to present back such information to interested stakeholders. And also information in the existing system could not be accessed globally. This is what the proposed system would accomplish.

The proposed system would present the detailed information globally via the internet to all users as its relevance would be much appreciated.

ADVANTAGES OF THE PROPOSED SYSTEM

1. Has a wider audience and coverage since the data is made available globally to a larger number of users and interested stakeholders. Hence any user with a computer and internet access can have access to the information presented on the site.

22

2. There is true representation or picture of real world objects in digital format. That is, the format of presentationis almost like real world situations.

3. It assists stakeholders, government officials in taking decisions at a very faster rate, since they are presented witha mapping system showing facilities and their respective locations

4. The system present a more interactive and user friendly interface.

5. This technology enhances developments, because a developmental activity becomes easy when one is presented witha comprehensive visual layout of facilities in a specific area.

DISADVANTAGE OF THE PROPOSED SYSTEM

1. Stakeholders without internet access won’t be able to have access to the system.

within automation boundary to specify programs and database. It also uses the flows outside the boundary to specify the user procedures. Finally the interface between the user and the computer system is designed.

4.2. DESIGNING USER PROCEDURES

User defines what people must do for the system to work. Two types design are important in user procedure design. One is functional design that is, making sure the system does what itis supposed to do. Functional design defines the task necessary to make the system work. These tasks must transform and move the data in the way specified by logical design. The other is job design that specifies what people must do within the tasks.

Flowcharting is one of the earliest representation tools for physical systems. A flowchart uses a finite set of symbols to represent system components. The following symbols are used torepresent computer components:

Operational objectives

This defines the performance standard to be achieved by the new system and include:

1. Change systems processes from computer based to on-line based system..

2. Easy generation of accurate and timely reports for effective decision-making.

3. Quick and easy to generate outputs.

Cost

There are two types of cost involved in the development of thenew system. They are

Development cost: consists of monies spent on all resources used to develop the system.

Operational cost: consist of cost incurred in operational activities of the new system.

Hardware Requirements

The minimum hardware requirements needed to run the new systeminclude;

1. A computer with Pentium ( p-1) microprocessor or above witha minimum of 64MB RAM.

Software Requirements

The new system requires a computer running SQL server as the back-end database engine.

Computer Interface

The computer interface is an important part of user proceduresdesign. It defines how the

users interact with a computer and has an important bearing on user’s acceptance of a

system. A good and easy-to use computer interface will make auser’s job more straightforward and pleasant. Consequently, the users will carry out the required work more

30

effectively. The purpose of the computer interface is quite simple. It is to capture information about the system from theusers and make this information available to all systems users. The supply of information is called the systems output.In any case the system output will be the reports that the system generate.

Online design used in this project calls for user-machine dialogues that permit rapid interchange of information betweencomputers and human users.

Different methods are used in online user dialog. The most commonly used and adopted in the design of the interface for this project is the menus and template.

Menus

A menu system presents the user with a set of actions and requires the user to select one of them. Once an option is selected, another menu is presented. Actions are selected, selecting options using the mouse.

Template

Templates are equivalent to forms on a computer. A form is presented on the screen and the user is requested to fill the form. Usually several labelled fields are provided and users enter data into the blank spaces.

Application Architecture

The system architecture is an important feature in an application because it defines the elements in the applicationand how elements in the application interact and what functionality each element provides. The three types of systems architecture are single-tier, two-tier and multi-tier.

Single-tier Application

In a single-tier application, only one layer supports the presentation, application logic, and data services. The data itself can be stored in any location such as on a server. However the functionality for accessing the data is part of the application. An example of a single-tier is Microsoft Excel where the application logic includes the calculation of total, spell check and other mathematical functions.

31

Two-tier Applications

Two-tier or standard client/server applications, group presentation and application logic components on the client machine and access a shared data source using a network connection. In a two-tier application, the user interface and business rules are a single layer that runs on a client computer (Microsoft press 1999). Separate application, such asSQL server or Oracle databases servers, provide the data services. Client/server applications are often two-tier applications such as visual basic application that calls a SQLserver stored procedure to provide data for the application. The visual basic application is one layer whiles the SQL Server data services are another layer.

The code for the user interface and business rules would not necessarily have to be within the same project; the visual basic application would call a dynamic link library (DLL) thataccess the data. Two-tier applications work well in

department-scale applications with low number of users (under 100), a single database, and secure, fast networking.

Multi-tier Applications

These are logic concepts. The three tiers are generally described as user (first), business (second or middle) and data (third); however, there can be more than three-tiers in amulti-tier application.

Because of this fact, multi-tier applications are sometimes referred to as n-tier applications where n is any number greater than or equal to three.

4.5. PROGRAM DESIGN

This aspect looks at the platform chosen for the design of both the front-end (User interface) and back-end database.

Front-End

The front-end development compiler chosen was Visual Basic 6.0(VB6)

Enterprise edition: It enables the programmer to design innovative user interfaces taking advantage of other applications from manipulating text and graphics to working with databases (MSDN 2000).

32

Back-End

The back-end or Database engine chosen was SQL. This permits multiple clients on the

network access, retrieval and manipulative right to data whiles protecting the data from

malicious use. It also provides an easy and flexible way of generating quick, easy to use and

comprehensive querying system for information processing. It flexibility and availability as

well as affordability compared to other Database engines made it the best choice for such

project.

CHAPTER FIVE

SYSTEM IMPLEMENTATION AND TESTING

5.1. INTRODUCTION

This chapter describes the detail steps taken to code, test and implement the programs that

are designed in the new system. The implementation plan describes how the system will be

developed, deployed, installed and transitioned into an operational system. The stages of

the implementation plan includes;

1. Application Development

2. Testing

3. Documentation

3. File Conversion

4. Changeover

5. Training

5.2. Application Development

This stage involves the implementation of the coding of the system design of geographic

information system. This actual coding was done with visual basic.Net (VB.Net). The coding

process followed the structured approach in developing the application. The design of the

system were classified in modules and coded accordingly. Thesemodules were finally

integrated by using coding that enables them to interlink to each other. Likewise the reports

were coded in different modules according to their functionality in the system application.

5.3. Testing

System testing is an integral and important part of the purpose of the software

development process. This part of the process ensures that bugs ( or errors) are recognized

34

as early as possible to be corrected. System testing ensures that the entire integrated

software system meets requirements. It tests a configuration to ensure known and

predictable results. System testing is based on process descriptions and flows, emphasizing

pre-driven process links and integration points. The tests that were performed for the new system is to achieve its purpose were unit, integrated and acceptance testing.

5.2.1. Unit testing

The first test in the development process is the unit test. The source code was divided into

modules, which in turn were divided into smaller units called units. These units have specific

behaviour. The test done on these units is called unit test. Unit tests ensure that each

unique path of the project performs accurately to the documented specifications and

contains clearly defined and expected results.

5.2.2. Integration testing

Integration testing follows unit testing and precedes system testing. This is testing in which

modules are combined and tested as a group. Modules are typically code modules,

individual application, client and server applications on a network, etc.

5.2.3. Acceptance testing

Testing to verify a product meets user specified requirements.A user does this type o

f testing on a product that is developed externally.

5.3. Documentation

The system documentation is the written descriptions and procedures about a program and

how to use it. A thorough documentation was at each stage of the development process.

For the purpose of future maintenance and enhancement, documentation is essential tool

to make the software complete.

35

Again, documentation would be important to people like users, operators and programmers

in the future as a reference guide.

5.4. File conversion

File conversion is the conversion of the computer data from one form data to another. The

objectives of file conversion is to maintain all of the data,and as much of the embedded

information as possible. But since most of the computer forms were designed to relate to

the existing files, there will not be great variation in the format.

5.5. Changeover

System changeover means the approach used to put the new system in place of the older system.

There are several changeover approaches such as parallel, direct, pilot, and phased operations method.

Direct implementation: This is when the user stops using the old system completely and start using the new system.

Parallel Implementation: This is the strategy whereby the old and the new systems are used

simultaneously until the new system is shown to be reliable.

Phased Implementation: Parts of the new system are phased intothe old one separately at

different times or all at once in groups in this implementation strategy.

Pilot Implementation: This is when the entire system is tied out by only some users of the

system and implemented with the remaining users when the reliability of the new system is proved.

The direct implementation will be used in this project.

In this project, there will be complete changeover from the older system to the new system.

36

5.6. Training

The training of the users who will use the new system is very important. The training will

enable the users adjust more easily and understand what entails in the usage of the new

system.

Therefore, all necessary training activities must be scheduledand coordinated. The training

session will particularly cover the system administrator. Thepeople will be shown how to

operate the system.

5.7. Conclusion

This chapter outlines the procedures involved in the implementation of the new system and

their functionality. The procedures include how the report wasdesigned to complement the

other major procedures such as testing, documentation, file conversion, changeover and

training to make the new system application complete.

37

CHAPTER SIX

CONCLUSION AND RECOMMENDATION

6.1. CONCLUSION

The project has been as challenging as it has been educative to me; it has enabled me to

utilize all the knowledge acquired over the three years of myeducation in the university.

The course taken in System Analysis and Design as well as High-Programming and System

Programming has helped me enormously to define, analyze and develop the program.

The course taken in Data Communication and Networking also helped me know the type of

networks available as well as the clients/server architecture. Choosing the platform to

develop the system was not all that easy but by consulting other programmers, I was able

to pick one, which was expensive and common to develop the system. The need for

consultation is therefore obvious.

After implementing and hosting the system on the web, users and stakeholders will be able

to access and acquire information about the respective facilities within the shortest period

of time and facilitate decision making as far as the facilities are concerned

6.2. RECOMMENDATION

1. It is highly recommended that in order for the system to run smoothly a Qualified

Systems Analyst be employed to see to the day to day smooth running of the system.

2. It is also recommended that a regular training session should be organized for the staff

that will be operating the system and also manuals or guidelines that can be used as

reference when they face any difficulties.

3. The system designer should be consulted on any challenges in using the system.
