Honestly, not sure what is meant by this. Bottom up sounds more like reverse engineering, but not sure.

The top-down data modeling technique will teach you how to create an integrated Logical Data Model, which is fully normalized and populated with key business attributes. The bottom-up data modeling technique will teach you how to validate and map source data into your Logical Data Model, as well as how to find dirty data in the source files and transform it using formal Normalization rules.
