Types of information systems
An information system is a collection of hardware, software, data, people and procedures that are designed to generate information that supports the day-to-day, short-range, and long-range activities of users in an organization.
Properties of TPS
Data Entry-Inputs:Transactions or events
Processing-Sorting; listing; merging; updating
Database Maintenance
Document And Report Generation-Outputs:Detailed reports; lists; summaries
Inquiry Processing
There are two types of TPS:
Batch processing transactions is the processing of the collection/storage of data at the time of the event with actual updating of the later when it is scheduled or there is enough data.

Real time transaction processing is the immediate processing of data with the database updated as the transaction is being carried out. For instance a POS terminal which requires the user input and an immediate feedback is needed.

The components of a transaction processing system including:
People from the environment

Storing and Updating
Real Time updating
Batch updating
