    Hi Lawrence,

    There is same discussion thred here under Performance section.

    Okay, First we will see what is BMP and What is CMP.

    In CMP, the contaier is responsible for the Persitence related Handling. The programmer need not to worry about the persistence related code. He can simply focus on the Business logic.

    In BMP, the programmer has to write all the persisitence related code. Definitely if programmer is well worse with database programming and he can write efficient code, BMP can be efficiet.

    Other than this BMP is not giving any advantage. Yes, if you have requirement to map more than one Table to one entity bean you have to go for BMP.

    But see, if the requirement is not like that, Than definitely we should go CMP only. After all it is well tested code. If you have specific queried please let me know.
