PLSQL logic to insert master detail records

Question

Hi All
I have a requirement where I need to do the following.
1: Have a headers and details table for some data that I need to insert
2: Transactions need atomicity...ie If the header record fails then the details should still be inserted , but with an Error flag
3: Needs good error handling
I'm trying to come up with some logic like so
1: Have a header cursor and a details cursor
2: Have the lines for loop inside the headers for loop and then do the inserts
3: If an exception is thrown for one record it should not error out the other records(this can be done with a begin end block)
Does anyone have a better idea for this...Is it an efficient way of developing header- detail inserts?
If someone has an example that I can go over I would appreciate that or a basic algorithm would do too..
Thanks

3: Needs good error handlingGood error handling is specific to the expected error and is defined by the specific business requirements.
