MetaModel
· MetaModel is a library that encapsulates the differences and enhances
the capabilities of different datastores. Rich querying abilities are
offered to datastores that do not otherwise support advanced querying
and a unified view of the datastore structure is offered through a
single model of the schemas, tables, columns and relationships.
