Software Requirements Specifications

1.0 Introduction

One of the most interesting aspect of online trading is the buying and selling of used or secondhand products. It makes the task of selling and purchasing used goods so much easier. With minimal marketing efforts from you as a seller or a reseller, you can be assured that prospective customers will still be available for the products that you are selling. Just make sure that you give a good description of your product, and more importantly good quality pictures of the products that you are selling so that you can be noticed by prospective buyers

1.1 PurposeThis project is aimed at developing a website for buying and

selling of the pre-used gadgets. It provides an interface for the customers and users to sell and buy second hand products.

If you want to save a bit of money then it can be a good idea to buy second hand electronic devices. It can be a risky business, buying second hand items and even more so with electronic devices.

2.0 Feasibility StudyDepending on the results of the initial investigation the survey is now expanded to a more detailed feasibility study. “FEASIBILITY STUDY” is a test of system proposal according to its workability, impact of the organization, ability to meet needs and effective use of the resources. It focuses on these major questions:

What are the user’s demonstrable needs and how does a candidate system meet them?

What resources are available for given candidate system? What are the likely impacts of the candidate system on the

organization? Whether it is worth to solve the problem?

During feasibility analysis for this project, following primary areas of interest are to be considered. Investigation and generating ideas about a new system does this.

Steps in feasibility analysisEight steps involved in the feasibility analysis are:

Form a project team and appoint a project leader. Prepare system flowcharts. Enumerate potential proposed system. Define and identify characteristics of proposed system. Determine and evaluate performance and cost effective of each

proposed system. Weight system performance and cost data. Select the best-proposed system. Prepare and report final project directive to management.

2.1 Technical Feasibility

10 | P a g e


Technical feasibility is the study of resource availability that may affect the ability to achieve an acceptable system. This evaluation determines whether the technology needed for the proposed system is available or not.

Can the work for the project be done with current equipment existing software technology & available personal?

Can the system be upgraded if developed? If new technology is needed then what can be developed?

This is concerned with specifying equipment and software that will successfully satisfy the user requirement. The technical needs of the system may include:

Front-end and back-end selectionAn important issue for the development of a project is the selection of suitable front-end and back-end. When we decided to develop the project we went through an extensive study to determine the most suitable platform that suits the needs of the academy as well as helps in development of the project.The aspects of our study included the following factors.

Front-end selection: It must have a graphical user interface that assists employees

that are not from IT background. Scalability and extensibility. Flexibility. Robustness. According to the organization requirement and the culture. Must provide excellent reporting features with good printing

support. Platform independent. Easy to debug and maintain. Event driven programming facility. Front end must support some popular back end like Ms Access.

11 | P a g e


According to the above stated features we selected Web Browser as the front-end for developing our project.

Back-end Selection: Multiple user support. Efficient data handling. Provide inherent features for security. Efficient data retrieval and maintenance. Stored procedures. Popularity. Operating System compatible. Easy to install. Various drivers must be available. Easy to implant with the Front-end.

According to above stated features we selected SQL Server as the backend.The technical feasibility is frequently the most difficult area encountered at this stage. It is essential that the process of analysis and definition be conducted in parallel with an assessment to technical feasibility. It centers on the existing computer system (hardware, software etc.) and to what extent it can support the proposed system.

2.2 Economical FeasibilityEconomic justification is generally the “Bottom Line” consideration for most systems. Economic justification includes a broad range of concerns that includes cost benefit analysis. In this we weight the cost and the benefits associated with the candidate system and if it

12 | P a g e


suits the basic purpose of the organization i.e. profit making, the project is making to the analysis and design phase.The financial and the economic questions during the preliminary investigation are verified to estimate the following:

The cost to conduct a full system investigation. The cost of hardware and software for the class of application

being considered. The benefits in the form of reduced cost. The proposed system will give the minute information, as a

result the performance is improved which in turn may be expected to provide increased profits.

This feasibility checks whether the system can be developed with the available funds. The USED PRODUCTS STORE does require enormous amount of money to be developed. This can be done economically if planned judicially, so it is economically feasible.

2.3 Operational FeasibilityIt is mainly related to human organizations and political aspects. The points to be considered are:

What changes will be brought with the system? What organization structures are disturbed? What new skills will be required? Do the existing staff

members have these skills? If not, can they be trained in due course of time?

The system is operationally feasible as it very easy for the End users to operate it. It only needs basic information about Windows platform.

3.0 System Analysis

13 | P a g e


System analysis uses a combination of text and diagrammatic forms to depict requirements for data, function and behavior in a way that is relatively easy to understand, and more important, straightforward to review for correctness, completeness and consistency.

3.1 Working of Present SystemIn present system, buyers and sellers used to go to either a retail outlet or contact some person after seeing an advertisement in newspaper or TV.This approach is quite time consuming as customer cannot buy the product as soon as possible. Here both money and time are wasted in comparison to sell or buy such product online.

3.2 Disadvantages of Present SystemSince, our present system has several disadvantages described below:

Lack of immediate retrievals: -The information is very difficult to retrieve and to find particular information. This results in inconvenience and wastage of time.

Lack of prompt updating: - Various changes to information are difficult to make as paper work is involved.

Preparation of reports: - This becomes a difficult task as information is difficult to collect from various registers.

3.3 Proposed System

14 | P a g e


The “USED PRODUCTS STORE” is web-based management system. If you want to save a bit of money then it can be a good idea to buy second hand electronic devices. It can be a risky business, buying second hand items and even more so with electronic devices. The following are a few ideas of what you need to be looking for when buying second hand items so that you don’t end up with buyer’s remorse.

- It is essential that you try out any second hand electronic device that you are considering before actually buying it. However be aware that not all problems will be instantly noticeable. Try to use as many of the functions as you can before you buy these devices.

- It is a good idea to check if the device you are considering is still supported before you buy it. If the device is not supported any longer then it could mean that you cannot fix it if it breaks and replacement batteries will not be available. And if the device uses a memory card, then you need to make sure that they can still be bought.

- Check to see if the game developers are still making games for the device if it is a games console or mobile gaming device.

- Get some help and advice from someone with a bit of knowledge about the device if you are not sure about it. If you want to make sure that you buy an appropriate device and not end up with something that you are sorry you bought, then you should really get this help.

3.5 E-R DiagramThe object/relationship pair is the cornerstone of the data model. These pairs are represented graphically using E-R diagrams. A set of primary components are identified for the ERD: data objects, attributes, relationships and various type indicators. The primary purpose of ERD is to represent data objects and their relationships.

17 | P a g e


3.6 DFDThe data flow diagram enables the software engineer to develop models of the information domain and functional domain at the same time. As the DFD is refined into greater level of detail, the analyst performs an implicit functional decomposition of the system. At the same time, the DFD refinement results in corresponding refinement of data as it moves through the processes that embody the application.

4.0 System DesignSystem design is a solution, a ‘how to’ approach to the creation of a new system. It provides the understanding and procedural details necessary for implementing the system recommended in the feasibility study. Emphasis is on translating the performance requirements into design specifications. Design goes through logical and physical stages of development. Logical design reviews the present physical system; prepared input and output specifications; details the implementation plan; and prepares a logical design walkthrough. The physical design maps out the details of the physical system, plans the system implementation, devises a test and implementation plan, and specifies any new hardware and software.
