The TPS of a university helps perform such tasks as enrolling Peoples are probably the components that most influence the successor failureĪ transaction processing system (TPS) supports the processing a firmsīusiness transactions. Often the most overlooked element of the computer based information system procedures are to people what software is to hardware is a commonĪnalogy that is used to illustrate the role of procedures in a computer basedĮvery computer based information system needs people if it is to be useful. Procedures are the policies that govern the operation of a computer system Programs, data are generally stored in machine readable form on disk or tape Stored on some input output medium often a disk or tape for use by the computer.ĭata are facts that used by programs to produce useful information. To function in way that produce useful information from data. ![]() The circuitry within the hardware parts of the computer based information system computer programs are machine readable instructions that direct The term software refers to computer programs and the manuals (if any) that Among these supporting equipments are input and outputĭevices, storage device, and communication devices. Itself, which is often refer to as the central processing unit (CPU), and all The term hardware refers to machinery, this category includes computers Such a system consists of the following elements FollowingĪre the some basic components of computer based information system (Mahar, 2003).Ĭomponents of computer based information systemsĪ computer based information system is an information system in which aĬomputer plays an important role. That information system would even be considered a serious field of study. In fact, without computers, it is unlikely Virtually impossible to study information system today without knowing some Information Technology Journal, 2: 128-134.Ĭomputers are an essential part of modern information systems, and it is Role of Information Technology in Transaction Processing System. This paper will cover some general properties of transaction processing systems, special transaction processing subsystem-pay roll, order entry, inventory, accounts receivable, accounts payable and others.Įngr. ![]() To most businesses, manual systems present numerous problems that are solved by computer and communication technologies. Many small businesses still operate with manual transaction processing systems however, inexpensive and easy to use computer technology is finding its way into more small businesses. These records would be set up to trigger statements to customers or checks of suppliers. ![]() These transactions would latter be transferred, manually, to a central system of hand written records or file folders representing individual customers or suppliers. Clerks would record transactions in a journal or on numbered multi part forms. Thus, the use of online processing ensures that inventory records exactly match actual unit counts in the warehouse at all times.The earlier transaction processing systems were manual systems. ![]() Under an older batch processing system, these inventory transfer transactions might not be loaded into the computer system until the following day - until then, the inventory location information stored by the system is inaccurate. Someone looking for inventory can then rely upon this information to determine the current location of the inventory. Example of Online ProcessingĪ warehouse staff can use online processing to scan the bar codes attached to items in the warehouse, thereby documenting the movement of these items from place to place in the warehouse. However, the attendant reduction in the real time accuracy of information in this environment still makes batch processing a lesser alternative to online processing. Online processing is a major factor in improving the usability of computer reports, since the information on them is more current.įrom a labor utilization perspective, batch processing can be more efficient than online processing, since employees can plow through a large number of transactions within a short period of time. The opposite of this system is batch processing, where transactions are allowed to pile up in a stack of documents, and are entered into the computer system in a batch. Online processing is the ongoing entry of transactions into a computer system in real time.
