Object Relational Database System:
Relational databases have the following limitations:
- Reusability of structure is not possible.
- A specific interface cannot be determined.
- Maintenance of the database has to be done on a continuous basis.
- Data is drawn from a limited set of data types.
In order to overcome these limitations, the concept of Object Relational Database Management System (ORDBMS) was introduced. The ORDBMS is a relational database that is object oriented on the front end. Applications interface with this database as if data is stored in the form of objects. The system converts these objects of information into data tables, which contain rows and columns, and then handles the data as in a relational database. After retrieving the data, it is reassembled back into complex objects. The ORDBMS was developed with the objective of enabling software developers to view problems from an enhanced level of data abstraction.
The ORDBMS enables the software developers to incorporate their customized data types and methods into the database. These databases support both object and relational models, thus enabling the reusability of the structure. It also provides a well-defined interface for applications. Data modeling and querying also become easier as the ORDBMS uses complex data types. The main advantage of the ORDBMS is that the programmer need not write any code for converting object data between RDBMS and object database as software for conversion is available.
Oracle 8 is an example of an ORDBMS. It enables objects to be defined as reusable software codes which are location independent and can perform a specific task on any application environment. This requires very little change to the code.
