In 3 tier architechure we used,
- Data Access Layer (DAL)
- Business Logic Layer (BLL)
- Presentation Layer
Data Access Layer contains all basic methods which we have to need like data set, data bind, data access from db etc.
You can refer following links to know more about data access layer and 3-tier architecture. It might helps you,
