Object Database Models

Object databases are designed to help unite database and application programming by ensuring that the database uses the same type system as the application program. This aims to avoid the overhead of impedance mismatch.

Impedence mismatch refers to converting information between its representation in the database [rows in tables] and its representation in the application program [objects].

Object Programming

Object programming uses techniques, such as encapsulation and polymorphism, for storing objects in a database. Some products approach this from the application programming end, others from the database end, by defining an object-oriented data model for the database, and defining a database programming language that allows full programming capabilities as well as traditional query facilities.
