TRANSACTION PROCESSING SYSTEM (TPS)

A TRANSACTION PROCESSING SYSTEM (TPS) is a system that captures, enters, stores, retrieves, and processes the relevant details of business events and generates the information and documents necessary for running the business.

WHERE IT IS BEING USED

Capturing the data as close to the source as possible Entering them into the system in a manner as effectively and efficiently as possible Storing them in the database Retrieving them from the database for furtherprocessing Transforming them from the raw form toinformation useful to the intended user.

\Examples of transaction processing systems are the systems used by banks and credit card companies to track customer's purchases using these cards. Transaction processing systems are designed to track and process individual operations. Same goes for POS systems

OFFICE AUTOMATION SYSTEM(OAS)Office automation refers to the varied computer machinery and software used to digitally create, collect, store, manipulate, and relay office information needed for accomplishing basic tasks. Raw data storage, electronic transfer, and the management of electronic business information comprise the basic activities of an office automation system

KNOWLEDGE WORK SYSTEM (KWS)The Knowledge Worker System (KWS) is a computer application designed to help knowledge workers (professionals who use information as their primary input and whose major products are distillations of that information) to capture and organize work activity information, and to learn, prioritize, and execute their tasks more efficiently and effec- tively. KWS integrates methods and technologies from the disciplines of information management, workflow, work scheduling, software agent, and work measurement into a Performance Support Environment. KWS enhances productivity by delivering task- specific information as needed, and by associating all automated tools, software agents, and multimedia document references needed to complete a specific task.

WHERE IT IS BEING USED

EXAMPLES

CAD/CAM systems: Computer-aided design (CAD) and Computer-aided manufacturing (CAM) systems automate the creation and revision of designs, using computers and sophisticated graphics software. They provide engineers, designers, and factory managers with precise manufacturing control over industrial design and manufacturing

Virtual reality systems: These use interactive graphics software to aid drug designers, architects, engineers, and medical workers by presenting precise, three-dimensional simulations of objects.

Investment workstations: These are high-end PCs used in the financial sector to analyze trading situations instantaneously and facilitate portfolio management.

DECISION SUPPORT SYSTEM (DSS)

Decision Support Systems (DSS) are a specific class of computerized information system that supports business and organizational decision-making activities. A properly designed Decision Support System is an interactive software-based system intended to help decision makers compile useful information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions.

WHERE IT IS BEING USED

Typical information that a decision support application might gather and present would be:Accessing all of your current information assets, including legacy and relational data sources, cubes, data warehouses, and data martsComparative sales figures between one week and the nextProjected revenue figures based on new product sales assumptionsThe consequences of different decision alternatives, given past experience in a context that is described

EXAMPLESThe DSSAT4 package, developed through financial support of USAID during the 80s and 90s, has allowed rapid assessment of several agricultural production systems around the world to facilitate decision-making at the farm and policy levels. There are, however, many constraints to the successful adoption on DSS in agriculture.DSS are also prevalent in forest management where the long planning time frame demands specific requirements. All aspects of Forest management, from log transportation, harvest scheduling to sustainability and ecosystem protection have been addressed by modern DSSs.A specific example concerns the Canadian National Railway system, which tests its equipment on a regular basis using a decision support system. A problem faced by any railroad is worn-out or defective rails, which can result in hundreds of derailments per year. Under a DSS, CN managed to decrease the incidence of derailments at the same time other companies were experiencing an increase.

EXECUTIVE SUPPORT SYSTEM (ESS)An Executive Support System (ESS) is software that allows users to transform enterprise data into quickly accessible and executive-level reports, such as those used by billing, accounting and staffing departments. An ESS enhances decision making for executives.ESS is also known as Executive Information System (EIS).

WHERE IS IT BEING USED

EXAMPLESExternal databasesTechnology reports like patent records etc.Technical reports from consultants Market reportsConfidential information about competitorsSpeculative information like market conditionsGovernment policiesFinancial reports and information

GROUP DECISION SUPPORT SYSTEMA Group Decision Support System (GDSS) is an interactive, computer-based system that helps a team of decision-makers solve problems and make choices. GDSS are targeted to supporting groups in analyzing problem situations and in performing group decision-making tasks (cf., DeSanctis and Gallupe, 1987; Huber, 1984). The name is very descriptive. A GDSS is a hybrid system that uses an elaborate communications infrastructure and heuristic and quantitative models to support decision-making.
