Techopedia Explains Object-Relational Database Management System

Object relational database management systems provide a middle ground between relational and object-oriented databases. In an ORDBMS, data is manipulated using queries in a query language. These systems bridge the gap between conceptual data modeling techniques such as entity relationship diagrams and object relational mapping using classes and inheritance. ORDBMSs also support data model extensions with custom data types and methods. This allows developers to raise the abstraction levels at which problem domains are viewed.
