Answer / yasi
Simple view derives data from only one table and contains NO functions or groups of data. And can perform DML operation through the view
Complex view derives data from many tables and contains functions or groups of data, It does not always allow DML operations through the view

Answer / siva kumari
A view which is created by only one table is called simple
view.A view which is created by more than one table (joins
and subquires) is called complex view.
we can not use any group by functions in simple view but we
can use group by function in complex view.
we can perform DML through simple views but we can not
always perform DML through complex view.

Answer / binod
A simple view is the one which is functioned on the single
table.whereas, a complex view is one that's functioned on
multiple table.
Simple view doesn't contains or consists function ,but
complex view contains functions.
In simple view we can't use groups of data but in case of
complex view it allows the group of function
DML operation is perform through simple view ,on the other
hand it is not allowed in case of complex

Answer / ketaki
simple view only contain a single base table, simple view does not contain group by, distinct , pseudocolumn like rownum, simple view does not contain columns defined by expressions , simple view does not contain not null columns from base tables.On such view DML can be performed.
Complex view can be based on more than one table , it can contain group by, distinct , pseudocolumn like rownum, columns defined by expressions can be included in complex views , not null columns that are not selected by simple view can be included in complex view, on such view we can not perform DML operations.
