1. There are four main types of information systems: operations support systems, management support systems, transaction processing systems, and office automation systems. 2. Operations support systems efficiently process and control business transactions through batch and real-time processing. 3. Transaction processing systems collect, store, modify, and retrieve business transactions through batch and real-time processing. Examples include ATMs and point-of-sale systems.

4. Transaction Processing System
A transaction processing system (TPS) collects, stores, modifies and
retrieves the transactions of an organization. Examples of such systems
are automatic telling machines (ATMs), electronic funds transfer at point
of sale (EFTPOS – also referred to as POS). There are two types of
transaction of processing:
– Batch processing: where all of the transactions are collected and
processed as one group or batch at a later stage.
– Real-time processing: where the transaction is processed immediately

Process control systems monitor and control industrial processes.
Office Automation Systems
The term office automation refers to all tools and methods that are applied to office
activities which make it possible to process written, visual, and sound data in a
computer-aided manner.
An office automation system (OAS) facilitates everyday information processing tasks
in offices and business organizations. These systems include a wide range of tools
such as spreadsheets, word processors, and presentation packages.
Office Automation Systems are software packages such as MS Office which include
word processors, spreadsheets, databases, presentation software, email, internet,
desktop publishing programs and project management software.
