![]() ![]() ![]() It contains data that has been formatted for presentation to the user. It helps to update master file and also serves as audit trails and transaction history. It is the collection of transaction records. Most transactions and databases are stored in master file. It contains information about an organization's business situation. The transaction processing system uses five types of files to store and organize data. This will then be calculated to find an approximate location of data.įiles used in Transaction Processing System: the storage device stores data in a particular location based on a mathematical procedure. This occurs when data are accessed without accessing previous data items. Hence it is difficult to maintain real time processing.Į) Updating in real time uses direct access of data. Each transaction is unique.ī) Real time processing requires the master file to be available more often for updating and reference.Ĭ) This processing has a fewer errors as the transaction data is validated and entered immediately.ĭ) More computers are required, as the operations are not centralised. It is very time consuming to locate specific transactions.Ī) Transaction in real time processing are stand alone both in entry to the system and also in handling the output. ![]() A batch will start at the beginning of the tape, then reading it from the order it was started. The only way to access data is by using a magnetic tape. Updating a batch requires sequential access. If an error occurs then the entire batch fails. This step is difficult because it requires the steps to occur in certain order. This data is then stored into transaction file.Ģ) The data is then processed by updating the master file. errors can occur during this step.Į) It is easy to maintain batch processing system.ġ) The transaction data is collected and sorted into sequential order. Transaction processing systems are of two types:Ī) Batch processing involves processing several transactions at the same time.ī) The result of each transactions are not available immediately when the transaction is being entered.Ĭ) The database or the master file need not to be accessed every time for batch processing.ĭ) With batch processing, data is organized and stored before the master file is updated. Therefore a well designed backup and recovery procedures is essential.Ĭ) A transaction processing system wants every transaction to be processed in the same way regardless of the user, the customer or the time for day.ĭ) The processing in a transaction system must support an organization's operation. Hence the turnaround time from the input of the transaction to the production for the output must be a few seconds or less.ī) For a processing system to effective, its failure rate must be very low. Business cannot afford to have customers for a processing system to respond. Requirements for an efficient working of transaction processing system:Ī) For an efficient transaction processing system, fast performance with a rapid response time is critical. It provides data which is summarized into information by systems used by higher levels of management. The important features of this system are:ġ) It is often tied to other system such as inventory system which tracks stock supplies and triggers recording when stocks get low.Ģ) It serves the most elementary day to day activities of an organization.ģ) It supports the operational level of business and supplies data for higher level management decisions.Ĥ) It usually has high volumes of input and output. Transaction is an event of interest to the organization.Ī transaction processing system is basic business system. A transaction processing system collects and stores information about transactions and control some aspects of transaction. Transaction Process System is a type of information system based on computer. A computer based information system refers to the specific application software that is used to store data records in a computer system and automates some of the information processing activities of the organization.Ī transaction processing system is a set of information which processes the data transaction in a database monitor that monitors transaction programs. ![]()
