Information systems (IS) play a critical role in organizations by helping manage data, support decision-making, and improve operational efficiency. Within the field of Management Information Systems (MIS), various models of information systems have been developed to categorize and explain their functions and applications. These models help in understanding how information systems interact with organizational processes.

The common models of information systems include:

1. Transaction Processing Systems (TPS): These systems handle routine, day-to-day business transactions such as sales order entry, payroll, and inventory control. TPS are designed to efficiently process large volumes of data and ensure accuracy and reliability.

2. Management Information Systems (MIS): MIS primarily generate reports and summaries from transaction processing systems to provide middle management with regular, structured information for decision-making and control purposes.
