									hai,
  i really confused waht does it mean data access layer and the business object  layer. I  want to know the difference between the two. And also i want to know, how the presentation layer communicates with the bussiness object layer and the data access layer, I mean how the presentation, business object and data access layer inter related.
  
  Thanks in advance.
