A view is a virtual table. Every view has a query attached to it. (The query is a SELECT statement that identifies the columns and rows of the table(s) the view uses.)
SQL> CREATE OR REPLACE VIEW myView (First_Name, Last_Name) AS
select First_Name,Last_Name
from Employee
where Salary > 2000;
View created.
SQL> drop view myView;
View dropped.
