object-oriented database


e> (OODB) A system offering ef="module.php?name=Lexikon&file=search&eid=1&query=DBMS">DBMS facilities in an ef="module.php?name=Lexikon&file=search&eid=1&query=object-oriented programming">object-oriented programming environment. Data is stored as ef="module.php?name=Lexikon&file=search&eid=1&query=objects">objects and can be interpreted only using the ef="module.php?name=Lexikon&file=search&eid=1&query=method">methods specified by its ef="module.php?name=Lexikon&file=search&eid=1&query=class">class. The relationship between similar objects is preserved (ef="module.php?name=Lexikon&file=search&eid=1&query=inheritance">inheritance) as are references between objects. Queries can be faster because ef="module.php?name=Lexikon&file=search&eid=1&query=joins">joins are often not needed (as in a ef="module.php?name=Lexikon&file=search&eid=1&query=relational database">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 ef="module.php?name=Lexikon&file=search&eid=1&query=type system">type system can be used to model ef="module.php?name=Lexikon&file=search&eid=1&query=data structures">data structures and the relationship between the different data items. ef="module.php?name=Lexikon&file=search&eid=1&query=Multimedia">Multimedia ef="module.php?name=Lexikon&file=search&eid=1&query=applications">applications are facilitated because the ef="module.php?name=Lexikon&file=search&eid=1&query=class">class ef="module.php?name=Lexikon&file=search&eid=1&query=method">methods associated with the data are responsible for its correct interpretation. OODBs typically provide better support for ef="module.php?name=Lexikon&file=search&eid=1&query=versioning">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 ef="module.php?name=Lexikon&file=search&eid=1&query=triggers">triggers and ef="module.php?name=Lexikon&file=search&eid=1&query=constraints">constraints which are the basis of ef="module.php?name=Lexikon&file=search&eid=1&query=active databases">active databases. Most, if not all, object-oriented ef="module.php?name=Lexikon&file=search&eid=1&query=application programs">application programs that have database needs will benefit from using an OODB. ef="module.php?name=Lexikon&file=search&eid=1&query=Ode">Ode is an example of an OODB built on ef="module.php?name=Lexikon&file=search&eid=1&query=C++">C++.
