Hi i want to develop an application in asp.net using 3 tier architecture .
i know that there are three layers
- Data layer
- Business Layer
- Data Access Layer
- Business Logic Layer
- Presentation Layer
I am confused between Data Access Layer and Business Logic Layer.
In data access layer we develop the property classes and main class function which returns datasets, datatables and data reader to Presentation layer.
what is the use of Business Logic Layer ? what actually we do in Business logic Layer ?? we can pass data directly from data access layer to presentation layer ?? can anyone give any small example to understand ??
