    The software that allows one or more persons to use, store, delete, modify and retrieve data that is stored in a database is a Data Base Management System (DBMS). Basic characteristics of DBMS are: Data Manipulation Language (DML), Data Definition Language (DDL), Data Base Manager. The author provides a schematic representation of a DBMS system and mentions its components i.e. entity set, attributes / keys, and relationship.
