Analysis of Transaction Processing Systems :: Computer Science Technology Essays

Analysis of Transaction Processing Systems It is the processing in which a system respond to a user’s command to carry out some operation to and fro. The request or command is called TRANSACTION, and the system carrying it out is called TRANSACTION PROCESSING SYSTEM e.g cash machines. Transaction processing systems are the systems working at a low level of any organizational structure being operated by data entry operators etc to collect and store data which is needed to be transported then to decisional level of organisations. But it is important to make sure nothing goes wrong at this level of handling data before it is transported to upper level to be manipulated and then making decisions based on information provided. â€Å"There is some support for the propositions that (1) Transaction processing systems should be able to be managed within each work group in an organisation, managed that is with respect to work stations in use and functionality available on those workstations. (2) exhibit very little model behaviour. (3) support a high degree of operator independence or asynchornity.† REFERNCE: http://www.csse.monash.edu.au/~cavram/papers/tp/tr94-02h.html There are 9 types of transaction processing models 1: Batch systems: 2: Monitor systems : 3: Time sharing systems 4: Advanced virtual terminal front end systems 5: Client server systems 6: Electronic mail and forms 7: Database based groupware 8: (IVR) systems 9: (EDI) systems â€Å"Transaction processing systems are information systems which collect data and distribute operational data both within and between organisations. The wide spread use of networks and personal computers (used as terminals) has provided feasible new options for the design of transaction processing systems† b. DECISION SUPPORT SYSTEMS: â€Å"Decision Support Systems (DSS) are a class of computerized information systems that support decision-making activities. DSS are interactive computer-based systems and subsystems intended to help decision makers use communications technologies, data, documents, knowledge and/or models to successfully complete decision process tasks† Reference: http://dssresources.com/ Decision support systems are the computer information application which collects and analyze data and then present it to the decision making people of organisation i.e managers . decision support system as the name suggest help and support managers to make effective ,right and timely decisions. These systems store and process data at a much higher and efficient speed and then represent the information in multiple forms which could be regular text , graphical representation, numerical etc which really enable managers to come up with timely and right decisions. As the decision makers could be different so can be the systems as some work individually while other work in teams there are differences in decision contexts, types, and makers. â€Å"There are certain common traits that decision-making processes tend to exhibit. They typically involve the phases of intelligence, design, and
