Concept:
DBMS is one of the most fundamental terms in computer science and information technology. It refers to software that is specifically designed to create, organize, maintain, retrieve, update, and manage data stored in databases.
A Database Management System acts as an interface between users and databases, ensuring that data remains organized, secure, accurate, and easily accessible whenever required.
Step 1: Understanding the full form of DBMS.
The acronym DBMS expands as:
\[
\text{DBMS} = \text{Database Management System}
\]
It is a collection of programs that enables users to define, construct, manipulate, and control databases efficiently.
Step 2: Analyzing each option carefully.
• Database Manipulation System: Incorrect. Although data manipulation is one function performed within a DBMS, this is not the official expansion.
• Data Base Management System: Correct. This is the accepted expansion of DBMS and represents software used to manage databases.
• Database Management Science: Incorrect. The word "Science" is not part of the standard acronym.
• Drive Barrier Management System: Incorrect. This term has no relation to database technology.
Step 3: Conclusion.
Therefore, the correct expansion of DBMS is Data Base Management System.
