Should I do this with Java Code or Stored Procs ? (for best performance)

Question

Hi All,
I need to decide where should I implement my business logic, in Java code or Stored procs.
Here is the requirement :
- One Order has 70 products (Order_Table )
- Can be duplicate products, so I have to do summarize / grouping by product
- For every product, I have to check, if it is entitled for a Bonus product, then I have to Insert one to Bonus_Table.
- This is done when/after the transaction is SAVED (COMMIT)
The question is, which one has better PERFORMANCE :
(1) Create a rowsetIterator on the Order details (70 products) and call a stored procedure to do the logic for every single product (so that the Insert to Bonus_Table done in stored proc). means the stored proc will be called 70 times.
OR
(2) After the transaction is COMMITted, call the stored procs ONCE to do the logic for all the products at once.
OR
(3) I do all the logic with Java Code within ADF
Given the requirement above, which approach is most efficient / best performance ?
Thank you very much,
xtanto

Problem with this is that you ask 100 people and you probably get 100 different answers. ;o)
Many would say that you push as much business logic into the database with your data; others might say you only put data in your database and your business logic is kept on the application server.
In reality your would probably have a mix of both and your decision would probably be influenced by your own background ...
Can't be more precise than that.
