[OSM-talk] Combining OSM data and my own data (CC-BY 4.0 license)

Essentially the OSM derived parts need to remain ODbL licensed, 
depending on the granularity of the "enriching" this might or might not 
effect the whole or just the OSM derived part of your database.

The later would not cause issues with most licenses, as they typically 
support a "collection" concept which allows separate licensing of the 
constituent parts (as the ODbL does), but CC BY 4.0 is viral^2 for 
databases and contains clauses that are substantially stricter than 
anything in the ODbL, so if you are publishing in the EU the answer is 
likely that it wont work.

and the other guidelines for more information.
