Package org.datanucleus.store.mapped Description

This package provides classes for the management of datastores that are "mapped". That is, any datastore that needs information for classes/fields to be mapped into tables/columns. This type of datastore would be something like RDBMS, which uses all of the concepts provided, or also Google BigTable that supports some ORM concepts.
