There are quite a few OODBMS companies with products on or just coming
on the market.  Here are the ones that I know of:

	Object Design
	Objectivity
	Ontologic
	Servio Logic
	Versant Object Technology
	Xidak

Most, if not all of them, offer C++ interfaces to their databases.
Most also have C interfaces, but the C interfaces generally are not 
as powerful (easy to use) as the C++ interfaces.  The various companies
give different tradeoffs (efficiency, transparency, languages supported,
size of databases, number of databases open at the same time, heterogenity,
distribution, locking, transaction model, schema definition, schema
modification, ...).
