Transaction Processing System (TPS)/Data Processing System

A transaction processing system (TPS) supports the processing of a firm's business transactions.

Transaction processing system keep on organization running smoothly by automating the processing of the large amount of paper work that must be handled daily. These systems include the accurate recording of transactions as well as the control procedures used in issuing such documents as pay checks, invoices, customer statements, payment reminders, tuition bills, and student schedules unlike other components of management information system, the transaction processing system of an organization extending out of the organization linking together the entire financial system, factory, customers, and suppliers. The movements toward Electronic Data Interchange (EDI) and the establishment of electronic links with suppliers & customers is an example of an extension of an organization's transaction processing system.

Sometimes, the term data processing system is used for TPS. The primary purpose of these systems is to effectively process the data that arise from transactions.

The transaction processing system of a departmental store can record customer purchases, prepare billing and booking of order from suppliers and inter-relate these tasks into an overall accounting system. The transaction processing system of a college helps performing such tasks as enrolling students in courses, billing students for tuition, and issuing pay cheque.

As discussed earlier, a transaction processing system supports the processing, of an organization's transactions this include recording of transactions as well as providing support activities such as sending payment reminders (which, although not transactions themselves, are related to transactions). Recently, going competitive advantage has become a transaction processing concern in some firms, especially these who are working to tie customers and supplier together more closely with the organization's traditional transaction processing system via electronic linkages.

Function of Transaction Processing System (TPS):

a. Book keeping:

Book keeping involves keeping accurate records of firm's business transactions. Every organization is involved with day-to-day business transactions between groups such as customers and suppliers, because these transactions establish linkage among them and are so important as bread & butter for human.

For example, banks typically both human tellers and automatic teller machines to record deposits & withdrawals of account holders. Colleges and universities record student registrations and fees paid by students. All of these tasks involve keeping accurate records of the firm's business transactions.

b. Issuance:

Issuance refers to the production of such documents as pay cheque, invoices, monthly telephone and credit card bills, and payment reminders. The creation of these documents is absolutely necessary to the effective operation of the company i.e. these documents are not discretionary.

Transaction

For many businesses, a transaction refers to an exchange of goods or services for money. For example, suppose a retailer buys 100 books from a wholesale. From the retailer's end, inventory is increased and a counterbalancing promise to pay the wholesaler is established. When payment is eventually made, the retailer loses cash, but this is counterbalanced by eliminating the payable charge on its records. Organizations such as academic institutions and hospitals have other ways of defining & dealing with transaction. In general a transaction is a recorded business event, often reflecting a routine exchange that affects the financial well being of an organization

Documents and Reports Generation:

The final stage of the TPS involves the generation of outputs such as documents and reports. Documents produced by a TPS are called transaction documents, which may be categorized as follows;

a. Information Document:

Information documents verify, Confirm, or prove that transactions have occurred or were attempted. Sales receipts, order confirmation, customer invoices, and customer statements may be generated to document that a transaction took place. A credit rejection notice may serve to communicate that a transaction was attempted, but | refused because of a problem in the customer's credit history.

b. Turn Around Document:

Some invoices and customer statements contains a perforated tear-off portion that should be returned to the sender, along with the customer's payment. When this type of document is generated by TPS, it is known as turnaround document.

c. Action Document:

Action documents initiate actions or transactions on the part of J recipients. A cheque authorizes the bank to cash, or a purchase; order similarly authorizes a supplier to send needed items to the organization that submitted it.

d. Accounting Statements:

These must be generated for legal purposes and legally document the financial performance of a business. These may include general ledger, trial balance, cash flow statements, balance sheets, and income statements. All of these are directly related to transaction processing activities.

e. Control Listing:

Control listings are detailed reports that describe each transaction' occurring during a specific time. period. These are sometimes called transaction logs. A payroll register will list every cheques issued by the payroll system.

f. Edit Report/Error Report:

Edit report/error report describe errors encountered during processing (or traditional data entry) are often called edit reports. Transaction involving invalid account numbers, incorrect totals, and missing data are usually listed in edit reports.
