Another issue is the selection problems. If you need to retrieve lots of records, say 1000 records, you will then have 1000 objects. Even though you can avoid this by using home business methods (finder or selector methods), you will then need to know about EJB-QL. In addition, if the records for display required other tables' values, performing a join or more joins makes the performance much more slower!
