A view logically represents subsets of data from one or more tables. You can restrict a user’s access to data in a table by using views. A view does not have a structure of its own and is stored as a SELECT statement in the database. Views are of two types, simple and complex: • Simple view: Retrieves data from only one table and contains no functions or group data. You can  perform DML operations through a simple view. • Complex view: Retrieves data from multiple tables or contains functions or group data. A complex  view does not always allow you to perform DML operations. Creating Simple View You create a simple view based on only one table. In other words, the SELECT statement of the view  retrieves data from only one table.
