Every week you can watch Mark as he builds out a Data Access Layer in Python. This library, called docbridge, is an attempt to build a Pythonic framework that takes into account the various patterns that are used when designing document models with MongoDB.

Paul Done's principles of evolvability (link below) state that you should only update the data that you know about, which means updating documents field-by-field, not overwriting. This is actually one of the big benefits of MongoDB! This week we'll look at how we can track changes to a data access object, and then write those back to the database.
