Looks like you are missing your Model-Class here.

Have:
1. Model class project - has all the object classes in it (your so called expected table structure)
2. Data Access Layer - Refer Model class DLL to use the object model
3. Business Logic Layer - Refer DAL dll & Model class DLL
4. Presentation Layer - Refer BLL & Model class DLL

This way, your architecure would be supporting the need and provide you layer system .
