11. Transaction Processing System
Functions
 Transaction processing systems consist of four main
functions to accomplish their purposes. They are:
1. Input function
2. Storage function
3. Processing function
4. Output function

12. Input Function
 Capture input data
 Enter input data
 Validate input data

13. Storage Function
 Data in a transaction processing system is stored in
data files and databases.
 Two types of data commonly found in transaction
processing systems:
1. Master data
2. Transaction data

14. Processing Function
 Processing involves manipulating data within the
system.
 Two operations in the processing function:
 Computation

17. Controlling Transaction Processing
Systems
 Procedures to ensure the completeness of the data
processing and to minimize the chance of error are
called controls. They include:
 Control Totals
 Audit Trails
 Backup and Recovery Procedures
 Processing Data in Transaction Processing Systems

18. Processing Data in Transaction Processing
Systems
 Two basic approaches to processing data in a
transaction processing system:
1. Batch processing – transactions to be processed are
prepared in a form understandable by the computer
before actual processing begins.
2. On-Line Transaction Processing (OLTP) – permits a
person to use a keyboard and screen at the time the
processing is done.

19. Example: Batch Processing and On-line
transaction Processing
