An object-oriented database management system (OODBMS), sometimes shortened to ODBMS for object database management system), is a database management system (DBMS) that supports the modelling and creation of data as objects. This includes some kind of support for classes of objects and the inheritance of class properties and methods by subclasses and their objects. There is currently no widely agreed-upon standard for what constitutes an OODBMS, and OODBMS products are considered to be still in their infancy. In the meantime, the object-relational database management system (ORDBMS), the idea that object-oriented database concepts can be superimposed on relational databases, is more commonly encountered in available products. An object-oriented database interface standard is being developed by an industry group, the Object Data Management Group (ODMG). The Object Management Group (OMG) has already standardized an object-oriented data brokering interface between systems in a network. >From: "Matthew Patterson" <[EMAIL PROTECTED]> >Reply-To: <[EMAIL PROTECTED]> >To: "Mysql list" <[EMAIL PROTECTED]> >Subject: relational DBMS vs object-relational DBMS >Date: Wed, 24 Oct 2001 14:33:58 -0500 > >Everything that I have read describes MySQL as a Relational DataBase >Management System (RDBMS).
