Hooks are implemented so you can interact with the "flow" of data within 
TYPO3.

Imagine something like this:
Data is entered by a user, the "SAVE" button is clicked and after that 
the "new" form is rendered.

Here you have at least two hooks you can "hook" into that flow.
a) before the data was actually stored in the database. Useful to 
validate things.
b) after the data was stored in the database. Useful when you need IDs 
of newly created records.

Check this out:

And also this might help you finding the hook you want to use:
processDatamap_afterDatabaseOperations()
