In SQL (Structured Query Language), a VIEW is a virtual table that represents the result of a stored query or a predefined SELECT statement. Essentially, a VIEW is a way to save and reuse complex queries without having to rewrite the entire query each time you want to access the same data.

A VIEW can be created using the CREATE VIEW statement, which consists of the following components:

- CREATE VIEW: The keywords used to define a new VIEW.
view_name: The name assigned to the new VIEW.
- AS: The keyword used to connect the VIEW name with the SELECT statement.
- SELECT statement: The SQL query that defines the data you want to store in the VIEW.
For example, if you have a database of employees and you want to create a VIEW that only shows the first name, last name, and salary of employees, you would write:

Code:
```
CREATE VIEW Employee_Summary AS
SELECT first_name, last_name, salary
FROM Employees;
```

Once the VIEW is created, you can query it just like you would query a regular table. For example:

Code:
```
SELECT * FROM Employee_Summary;
```

It's important to note that a VIEW does not store the actual data; it only stores the SQL query that retrieves the data. When you query a VIEW, the underlying query is executed, and the result is computed based on the current data in the underlying tables. This means that any changes in the underlying data will be reflected in the VIEW.
