Solution
The correct answer is d.1,3,4.
Here's why:
-
Easy to use: Yes, MySQL views simplify the process of running queries. Instead of having to remember and type out a complicated query, you can save it as a view and refer to it later.
-
Fast data query: This is not necessarily true. Views in MySQL don't always improve query performance. In fact, in some cases, they can make queries slower.
-
Safe: Yes, views can provide an extra layer of security by restricting the data that certain users can see.
-
Data independence: Yes, views can provide a level of abstraction from the database schema. This means that you can change the schema without affecting the view.
