The document provides an overview of enterprise systems and their key components. It discusses how traditional systems operated with departments working in isolation without communication or shared data. An enterprise system creates a single integrated system where information is stored centrally and available to all departments. This allows each subsystem to understand what others are doing to achieve common goals. Key aspects of enterprise systems include business modeling, integrated management information systems, and integrated data modeling.

- 9. Management Information System is an integrated information system One of the popular subsystem/ technology used in ERP It provided information system for decision-making in organization MIS elements Transaction process (collecting, storing, processing) Reporting System (gives reports.
