  2. CMP with Multiple tables[ Go to top ]

    If you are refering to using one CMP bean for multiple tables, it is unfortunately a vendor specific OR mapping. I am aware of BEA, but I am sure that others have as well.

    Using Container Managed Relationships is the way to go for multi-table access.

  3. Use BMP instead...[ Go to top ]

    1. As a general rule of thumb, use BMP.
    2. You may use a O/R mapping tool like TopLink too.
  4. Use a view[ Go to top ]

    Using a database view might help..
