2. False

Answer 1

option 1,The BEFORE trigger in a database management system can be used to access system-updated field values and affect changes in other records.

Step-by-step explanation:

The statement is True. The BEFORE trigger in a database management system can be used to access system-updated field values and affect changes in other records. A trigger is a set of actions that are automatically executed or fired in response to a specified event or condition.

For example, let's consider a scenario where we have an Orders table and a Products table in a database. When a new order is inserted into the Orders table, a BEFORE trigger can be used to update the stock quantity of the corresponding product in the Products table. The trigger can access the system-updated field values (such as the quantity ordered) and modify other records (such as reducing the stock quantity).

This is a powerful feature provided by database management systems to automate and maintain data integrity.Triggers can be used to enforce business rules, perform calculations, validate data, and more.
