datamapper

Let's say I have a data mapper function that aggregates multiple tables and generates an object instance from that data. The mapper has a typical save() method which delegates to update/insert.

When the mapper executes save - ideally it isolates object fields that have been modified, thus preventing the code from blanket bombing the database.

How would you go about this?
