Which statement best defines the difference between a regular view and a temporary view?

1. Regular view is permanent, temporary view does not persist and is session scoped.

2. There is no difference between both types of views.

3. Regular view is associated with a specific database, temporary view is system-wide.

4. Regular view requires user permissions, temporary view does not.

The correct answer is: Regular view is permanent, temporary view does not persist and is session scoped.

The statement accurately captures the fundamental distinction between a regular view and a temporary view in database management systems. A regular view is indeed a permanent database object that is stored within the database schema, maintaining its definition even after the user session ends. This allows users to reference the view just like a table and access its data without needing to redefine it. On the other hand, a temporary view is designed for a more transient scope. It exists only for the duration of a user's session or until it is explicitly dropped. This session scoping means that once the session ends, the temporary view ceases to exist, reducing overhead and allowing for dynamic data manipulation within a given session without affecting the broader database structure. The other options do not accurately reflect the nature of the views in question. While regular views indeed require user permissions for access, it is not the sole distinguishing factor compared to temporary views. Additionally, the claim that a temporary view is system-wide is misleading; it is actually scoped to the session that created it. Understanding these differences can help you make informed choices regarding data access and management in various scenarios.
