Hi,
DTO Layer
class EmpDTO
{
// variables declares
}
DA Layer
class EmpDAL
{
public void AddEmp(EmpDTO DTO)
{
// body of method
}
}
BA Layer
Class EmpBAL
{
EmpDAL DAL=new EmpDAL();
public void AddEmp(EmpDTO DTO)
{
DAL.AddEmp(DTO);
}
}
like the above architecture,in many articles Business layer contains only calling the DAL methods only
but in explanation saying it is use to write business logic
i want to know for what we use business layer
we can write any logic here, if so how to write
please give me nice sample code how we can use the architecture in real time projects
thanks in advance
waiting for reply....
