Which of the following correctly describe the sequence of the DBMS operational process?

database

  1. User issues request -> DBMS retrieves relevant mappings and executes the request DBMS intercepts the request DBMS presents the request to the user.

  2. User issues request -> DBMS intercepts the request DBMS retrieves relevant mappings and executes the request DBMS presents the request to the user.

  3. User issues request -> DBMS retrieves relevant mappings and executes the request DBMS presents the request to the user DBMS intercepts the request.

  4. None of the above

Correct Option: B
Explanation:

In a DBMS operational process, the correct sequence is typically as follows:

User issues request -> DBMS intercepts the request -> DBMS retrieves relevant mappings and executes the request -> DBMS presents the request to the user.

Let's go through each option and determine if it matches the correct sequence:

A. User issues request -> DBMS retrieves relevant mappings and executes the request -> DBMS intercepts the request -> DBMS presents the request to the user.

This option does not match the correct sequence. The DBMS intercepts the request before retrieving relevant mappings and executing the request.

B. User issues request -> DBMS intercepts the request -> DBMS retrieves relevant mappings and executes the request -> DBMS presents the request to the user.

This option matches the correct sequence. The DBMS intercepts the request first, followed by retrieving relevant mappings, executing the request, and presenting the request to the user.

C. User issues request -> DBMS retrieves relevant mappings and executes the request -> DBMS presents the request to the user -> DBMS intercepts the request.

This option does not match the correct sequence. The DBMS intercepts the request after retrieving relevant mappings and executing the request.

Therefore, the correct answer is:

B. User issues request -> DBMS intercepts the request -> DBMS retrieves relevant mappings and executes the request -> DBMS presents the request to the user.

None of the above options match the correct sequence.
