Answer: Option D
Solution (By Examveda Team)
In MySQL, a "VIEW" is like a special kind of shortcut. It lets you create a simplified way to look at data from one or more tables without actually changing the original tables.Think of it like this: You have a big, complicated recipe book with many recipes. A VIEW is like a smaller recipe book that pulls together only the recipes you use most often, making it easier to find what you need.
Here's how VIEWS are helpful:
Option C: To simplify complexity of database design
- VIEWS can make complex queries easier to understand and use. You can create a VIEW that combines data from multiple tables in a way that makes sense for a specific task.
Option B: To hide the complexity of the database
- VIEWS can hide the underlying structure of the database from users. This is useful for security or for making the database easier to work with.
Option A: To hide columns from the users
- While you can choose which columns to include in a VIEW, it's not specifically about hiding columns.
Option D: All of the mentioned
- This is the best answer! VIEWS are designed to simplify database design, hide complexity, and provide easier ways to access specific data.
