Analysis of Transaction Processing Systems :: Computer Science Technology Essays

Analysis of Transaction Processing SystemsIt is the process in which a schema of rules respond to a users command to verbalise out some(a) operation to and fro. The request or command iscalled TRANSACTION, and the system carrying it out is calledTRANSACTION PROCESSING SYSTEM e.g cash machines. Transactionprocessing systems atomic number 18 the systems working at a low train of anyorganizational structure being operated by information entry operators etc to clear and store data which is needed to be transported past todecisivenessal level of organisations. just now it is important to make surenothing goes wrong 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 frequent for the propositions that(1) Transaction processing systems should be able to be managed within individually work group in an organisation, managed that is with respect towork stations in use and function ality available on thoseworkstations.(2) exhibit very little shape 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 virtual terminal front end systems5 guest 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 widelyspread use of networks and personal computers (used as terminals) has providedfeasible new options for the blueprint 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 intend to help decis ionmakers use communications technologies, data, documents, 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 posture it to the decision makingpeople of organisation i.e managers . decision support system as the namesuggest help and support managers to make effectual ,right and timely decisions.These systems store and process data at a a good deal higher and efficient speed andthen represent the information in multiple forms which could be regular text ,graphical representation, numerical etc which genuinely enable managers to comeup with timely and right decisions.As the decision makers could be different so can be the systems assome work individually while other work in teams in that location are differences indecision contexts, types, and makers.There are certain special K traits that decision-making processes tendt o exhibit. They typically involve the phases of intelligence, design, and
