Object-Relational database model

While some database vendors have put enforce to bring to the market pure Object-Oriented databases, existed vendors of mature RDBMS products also have try integrate Object features into their Relational databases. As result was born another data model - Object/Relational.

Object/relational database management systems (ORDBMSs) add new object storage capabilities to the relational systems at the core of modern information systems. These new facilities integrate management of traditional fielded data, complex objects such as time-series and geospatial data and diverse binary media such as audio, video, images, and applets.

As an evolutionary technology, the object/relational (OR) approach has inherited the robust transaction- and performance-management features of its relational ancestor and the flexibility of its object-oriented brothers.

Database designers can work with familiar tabular structures while assimilating new object-management possibilities.
