introduction to Database Management System - Meta-Data and Data Modeling
A database management system (DBMS) is system software for creating and managing databases. The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data. These are systems that can be used to manage transactional databases, such as HR systems, banking systems and so on. There are several advantages of database management systems.
