TRANSACTION PROCESSING SYSTEM
An Overview of the Transactional Processing System




                                                     1
Transaction Processing System (TPS)

• A transaction processing system (TPS) provides data for other
  business processes


   – Management information system/decision support system
     (MIS/DSS)


   – Special-purpose information systems




                                                                  2

Transaction Processing System (Continued)

• TPSs


   – Process the detailed data necessary to update records about
     the fundamental business operations


   – Include order entry, inventory control, payroll, accounts
     payable, accounts receivable, the general ledger, and more




                                                                   4
Traditional Transaction Processing
Methods and Objectives

• Batch processing system: method of computerized processing in
  which business transactions are accumulated over a period of time
  and prepared for processing as a single unit or batch


• Online transaction processing (OLTP): computerized
  processing in which each transaction is processed immediately,
  without the delay of accumulating transactions into a batch



                                                                   5
Traditional Transaction Processing
Methods and Objectives Performance Reviews
(Continued)
• Online entry with delayed processing: transactions are entered
  into the computer system when they occur, but they are not
  processed immediately

• Organizations expect their TPSs to:

   – Process data generated for and about transactions

   – Maintain a high degree of accuracy and integrity
                                                              6
   – Produce timely documents and reports

Transaction Processing Activities

• TPSs

   – Capture and process data that describes fundamental business
     transactions

   – Update databases

   – Produce a variety of reports

• Transaction processing cycle: the process of data collection,
  data editing, data correction, data manipulation, data storage, and
  document production
                                                                    9

   – The process of capturing and gathering all data necessary to
     complete transactions

• Data editing

   – The process of checking data for validity and completeness.

• Data correction

   – The process of reentering miskeyed or misscanned data that
     was found during data editing.
                                                                    12
Transaction Processing Activities (Continued)

   – The process of performing calculations and other data
     transformation related to business transaction.

• Data storage

   – The process of updating one or more databases with new
     transactions.

• Document Production

   – The process of generating output records and reports.
                                                              13

  products from the organization, with the objective of delivering
  quality products on time to customers


• Inventory-control system: updates the computerized inventory
  records to reflect the exact quantity on hand of each stock-keeping
  unit




                                                                     18

• An invoicing application looks up the full name and address of the
  customer, determines whether the customer has an adequate
  credit rating, automatically computes discounts, adds taxes and
  other charges, and prepares invoices and envelopes


• Customer relationship management (CRM) system: helps a
  company manage all aspects of customer encounters, including
  marketing and advertising, sales, customer service after the sale,
  and programs to retain loyal customers

  processes that must be restored first in the event of a disaster and
  specification of what actions should be taken and who should take
  them to restore operations
