It is a database designed to store objects. Now isn't that helpful. :-) An object database is tightly coupled to an object oriented programming language and allows you to persist object instances between invocations of a program. Most implementations are for C++, Java, Smalltalk and recently Python though never at the same time. They are good for some specialized applications that are difficult or impossible to map to a relational model but are not a good general data storage mechanism because of the intimate coupling with a particular programming language and difficulty in querying. There is a standard from the ODMG http://www.odmg.org that helps on the interoperablity front but object database popularity is rapidly declining. Most object database vendors are now trying to turn their products into XML databases.
