It's generally used as a black box. 
Zope developers typically don't interact directly with the ZODB the way that
a java developer might with an RDBMs. The low-level storage details
are mostly automatic, and therefore irrelevant to your needs.

Explore some instances in the ZMI and if that's not enough, Use The Source.

by exploring in the ZMI, by using the source if you want to know how an
object REALLY works, and / or by using the interactive debugger to 
explore things.
