Final answer:
The term CRBMDS seems incorrect, but it is likely referring to a DBMS, which is software for creating and managing relational databases, enabling data entry, manipulation, and retrieval.
Step-by-step explanation:
The acronym CRBMDS mentioned in the question seems to be a typo or an incorrect term. However, based on the description provided, it appears the student is asking about a DBMS (Database Management System), which is a software program used to create and manage relational databases. A DBMS allows users to enter, manipulate, and retrieve data efficiently. For instance, popular relational DBMS software includes Microsoft SQL Server, Oracle Database, MySQL, and PostgreSQL, among others. These systems enable the creation of databases where data is stored in tables, with relationships between these tables defined, hence the term 'relational database'.
