object-oriented database
     
         (OODB) A system offering {DBMS} facilities in an
        {object-oriented programming} environment.  Data is stored as
        {objects} and can be interpreted only using the {method}s
        specified by its {class}.  The relationship between similar
        objects is preserved ({inheritance}) as are references between
        objects.  Queries can be faster because {joins} are often not
        needed (as in a {relational database}).  This is because an
        object can be retrieved directly without a search, by
        following its object id.
     
        The same programming language can be used for both data
        definition and data manipulation.  The full power of the
        database programming language's {type system} can be used to
        model {data structures} and the relationship between the
        different data items.
     
        {Multimedia} {applications} are facilitated because the
        {class} {method}s associated with the data are responsible for
        its correct interpretation.
     
        OODBs typically provide better support for {versioning}.  An
        object can be viewed as the set of all its versions.  Also,
        object versions can be treated as full fledged objects.  OODBs
        also provide systematic support for {triggers} and
        {constraints} which are the basis of {active databases}.
        Most, if not all, object-oriented {application programs} that
        have database needs will benefit from using an OODB.
     
        {Ode} is an example of an OODB built on {C++}.
