Analysis of Transaction Processing Systems :: Computer Science Technology Essays

Analysis of Transaction Processing SystemsIt is the touch on in which a dust do to a users command to carry out close to operation to and fro. The request or command iscalled TRANSACTION, and the system carrying it out is calledTRANSACTION touch on SYSTEM e.g cash machines. Transactionprocessing systems argon the systems working at a low level of anyorganizational structure being operated by data entry operators etc tocollect and store data which is needed to be transported then todecisional level of organisations. But it is important to make surenothing goes revile at this level of handling data before it istransported to upper level to be manipulated and then making decisionsbased on information provided.There is some body forth for the propositions that(1) Transaction processing systems should be able to be managed withineach work group in an organisation, managed that is with respect towork stations in use and functionality available on thoseworkstations.(2) exhibit very l ittle model behaviour.(3) support a high degree of operator independence or asynchornity.REFERNCEhttp//www.csse.monash.edu.au/cavram/ papers/tp/tr94-02h.htmlThere are 9 types of transaction processing models1 Batch systems2 Monitor systems 3 Time sharing systems4 Advanced realistic terminal front end systems5 Client server systems6 Electronic mail and forms7 Database based groupware8 (IVR) systems9 (EDI) systemsTransaction processing systems are information systems which collect data anddistribute operational data both within and between organisations. The widespread use of networks and personal computers (used as terminals) has providedfeasible new options for the design of transaction processing systemsb. DECISION SUPPORT SYSTEMSDecision Support Systems (DSS) are a class of computerized informationsystems that support decision-making activities. DSS are interactivecomputer-based systems and subsystems intended to help decisionmakers use communications technologies, data, document s, knowledgeand/or models to successfully complete decision process tasksReference http//dssresources.com/Decision support systems are the computer information application which collects and analyze data and then present it to the decision makingpeople of organisation i.e managers . decision support system as the namesuggest help and support managers to make effective ,right and timely decisions.These systems store and process data at a much high and efficient speed andthen represent the information in multiple forms which could be regular text ,graphical representation, numerical etc which really enable managers to germup with timely and right decisions.As the decision makers could be different so can be the systems assome work individually darn other work in teams there are differences indecision contexts, types, and makers.There are certain common traits that decision-making processes tendto exhibit. They typically involve the phases of intelligence, design, and
