Principle 3 – Data Manipulation Language Database management systems (DBMS) STUDY. A database management system (DBMS) is a software package designed to define, manipulate, retrieve and manage data in a database. To define DBMS simply, “Database Management System is software which allows the users to CREATE, UPDATE, DELETE and RETRIEVE the data or the records stored”. The organization of the data, derived from a close analysis of data requirements and data usage, is the most important design decision.
