I have 3 layers 1) Client 2)Business Access Layer 3) DataAccessLayer
Client interacts with Business Access Layers which return Datasets and Integer values
Business Access Layer Just has a Reference added in bin and on top (Using Namespace.DAL) and it requests the respective functions from DAL Layer. Client interacts with BAL only.
BAL Layer has all functions as Public / DAL Layer has all functions as public
Should I chang the DAL layer functions to protected Friend etc( BAL doesnot inherit from DAL Again)
It only has reference of DAL DLL
