object database - Computer Definition
A database that is managed by an object-oriented database management system (ODBMS). Object databases are closely aligned with a particular object-oriented programming language and enable the data in the objects to be persistently stored without requiring conversion to a relational database (see O-R mapping). A fair amount of tedious code is eliminated, and the object data are stored much faster. Complex Structures Object databases are also suited for applications that are not necessarily based on an object model, but use a large number of in-memory indexes that are difficult to store in a relational database. Object databases may be used for real-time applications whereby they can extend memory beyond the operating system's own virtual memory limit. Object Vs. Relational Examples of object-oriented databases are ObjectStore (www.ignitetech.com) and Versant Object Database (www.versant.com). Relational databases have also added object-oriented features; for example, UniSQL was one of the first products to support both structures. See universal server, ODMG and object-oriented programming.
