Here are few differences between simple and complex views.

1. A Simple view selects from one table. A Complex view selects from one or more tables.
2. A Simple view does not contain functions but Complex views contain functions.
3. You can perform DML through Simple views but you cannot always perform DML through Complex views.

Basically a simple and complex views can be differentiated based on the relations, functions and groups of data not by number of tables in the views.

Ex: We can not apply Insert, Delete and Update on a complex view directly, Let us say we have column returning the count in a view.
The same can be possible on a simple view.
