Object Relational Database

"C++ Object Databases" is the indispensable guide and reference to programming with C++ object databases. With this book, you will gain a thorough knowledge of the underlying modeling concepts, interfaces, and architectures. To ease the transition to object database programming, comparisons with relational databases and SQL are provided, including contrasts with the object facilities planned for SQL3. Object databases uniquely support an object-oriented data model that is shared by the database and the application, and their tight integration with an object programming language allows developers to realize increased productivity. OQL provides excellent declarative query access to objects, supporting the same object model used by the application. C++ is currently the dominant language supported by object databases and therefore is the basis for this book. As most object database vendors now support ODMG interfaces in their products, a working knowledge of the topics herein is essential to object database programmers. The author is uniquely qualified to present this material. He serves as the ODMG C++ Editor and has been co-editor of three ODMG books, covering releases 1.1, 1.2, and 2.0.

There are currently two 'camps' for database development -- relational, which is predominant and object, which is growing. There are many that feel the relational model is stronger, more proven but that the object model offers greater options. This book is a proposal for the future direction of data and database management systems (DBMSs). Building off Codd's relational model of data, the book presents a formal definition of an abstract model of data and can be considered as a blueprint for the design of a DBMS and a database language. This offers a rock-solid foundation for integrating relational and object technologies, a foundation that is evolutionary, not revolutionary.

Object-relational database - An object-relational database (ORD) or object-relational database management system (ORDBMS) is a relational database management system that allows developers to integrate the database with their own custom data types and methods. The term object-relational database is sometimes used to describe external software products running over traditional DBMSs to provide similar features; these systems are more correctly referred to as object-relational mapping systems.

Comparison of object-relational database management systems - The following tables compare general and technical information for a number of object-relational database management systems. Please see the individual products' articles for further information.

Object-Relational impedance mismatch - The Object-Relational Impedance Mismatch refers to a set of conceptual and technical difficulties which are often encountered when a relational database is being used by a program written in an object-oriented programming language or style; particularly when objects and/or class definitions are mapped in a straightforward way to database tables and/or relational schemata. This practice has been recommended and documented by some object-oriented literature as a way to use databases in object-oriented programs.
