Triggers can be defined on a system catalog table (True or False)

  1. True

  2. False


Correct Option: B
Explanation:

A system catalog is a group of tables and views that incorporate important information about a database. It includes tables that contain information about schemas, tables, columns, users, and so forth. A database management system (DBMS) typically manages these system catalog tables, and they are used to maintain consistent and reliable database operations.

While it's technically possible to create triggers on regular tables in a database, system catalog tables are typically not allowed to have triggers. The system catalog tables are managed by the DBMS itself, and any modifications to these tables are tightly controlled to avoid inconsistency or corruption of the system catalog. Therefore, DBMSs usually restrict users from creating triggers on system catalog tables.

Let's go through each option to understand why it is correct or incorrect:

Option A) True - This option is incorrect because system catalog tables are managed by the DBMS, and it typically prevents users from creating triggers on these tables.

Option B) False - This option is correct because, as mentioned above, creating triggers on system catalog tables is usually not allowed.

The correct answer is B) False. This option is correct because creating triggers on system catalog tables is typically not permitted by the DBMS to prevent potential data inconsistencies or system corruption.
