Which of the following is NOT a function of a DBMS?a) Data Retrievalb) Data Manipulationc) Data Encryptiond) Data Storage

To determine which option is NOT a function of a Database Management System (DBMS), we should first understand what functions a typical DBMS performs.

1. Data Retrieval: A DBMS provides the capability to retrieve data from the database. This is a primary function, allowing users to access stored information.

2. Data Manipulation: DBMS enables users to manipulate data through operations such as insertion, updating, and deletion. This function is essential for maintaining the database.

3. Data Storage: A DBMS stores data in an organized manner, making it a fundamental function of the system.

4. Data Encryption: While security and management of data might involve encryption, it is not a core function of a DBMS itself. Encryption is often handled at a different layer or service.

Conclusion

Based on this analysis, the correct answer is:

c) Data Encryption is NOT a core function of a DBMS.
