Introduction to Object-Relational Database Development

 

 

This book describes the Object-Relational Database Management Systems (ORDBMS) technology implemented in the INFORMIX Dynamic Server (IDS) product, and explains how to use it. This first chapter introduces the basic ideas behind object-relational, or extensible, DBMSs. It is intended as a road map to guide readers in their own exploration of the material. We begin with a little historical background explaining the motivation behind an ORDBMS product such as IDS. At this early stage of the book, it is enough to say that ORDBMS technology significantly changes the way you should think about using a database. In contrast with the more byte-oriented Relational DataBase Management System (RDBMS) technology, an object-relational database organizes the data and behavior of business objects within an abstract data model. Object-Relational query statements deal with objects personal name, part, code, polygon and video, instead of INTEGER, VARCHAR or DECIMAL data values. [via]
