Can anyone help me..... Please
Recently I was working in my BSc final year project about a Retail Solution using c# (Distributed System). I am using DAO and Facade and I have implemented 4 DAO, those are
1. Global DAO for user verifications
2. System Admin DAO for system admin operation
3. Warehouse DAO for Warehouse Operation.
3. Local Store DAO for local Store Operation.
But the problem is someone told me that, the way I have implemented my DAO class in not correct. But she also did not tell me which one is correct. If I implement different DAO for some individual role that what is the problem. Because those client application might not run in one computer can be different places
Please help me .
