Hiya.

I am pretty new to DNN.  I am a DBA by trade and want to change a lot of the User Schema.  Not a complete overhaul I suppose, just things like making the rowid a uniqueidentifier instead of the ever present webscriptable incrementable integer.  As well the solution I am building has other associations like Company that need association tables (users can belong to more than one company in my app).  So I am wondering if any has a UML map of how the user/membership api works.  I have been scoring thru the app and can't quite find the right bl or dal for everything I need.

Basically I would like to keep all the cool stuff like user roles, registration email, session info etc and add addiditional functionality.  Any help would be greatly appreatiated.

Thanks for the info and the quick response Cathal.  I will read through those docs.  I am however going to have to jury rig the providers becaue what I am building has a pretty elaborate database schema of its own.  Unfortunately the ProfilePropertyDefnition table et al will not work for me. 

Thanks Again,
