Hi Dipa A view is a virtual table based on the result-set of an SQL statement. A view contains rows and columns just like a real table. The fields in a view are fields from one or more real tables in the database. Watch given below video link for better understanding. https://www.youtube.com/watch?v=VQpmOmZO2mo We can create and drop view using below commands. Create Command CREATE VIEW view_name AS SELECT column1 column2column3 column4 FROM table_name WHERE condition; Drop Command DROP VIEW view_name;

Views can join and simplify multiple tables into a single virtual table. For example if the table consists of employee's name gender Id salary column respectively. I want to give access to my accountant team about the employee details whose salary more than 50000 without exposing the salary details. I can create the view with the required details and then the access can be given to the accountant team. Not need to create seperate table for this. CREATE View Employeelist AS SELECT NAME GENDER FROM [assignment].[dbo].[EMPLOYEE] WHERE SALARY>40000
