Submitted by admin on Thu, 2007-03-08 11:57
Any organization that uses the Oracle relational database management system (RDBMS) these days needs to use multiple databases. There are many reasons to use more than a single database in a distributed database system:
- Different databases may be associated with particular business functions, such as manufacturing or human resources.
- Databases may be aligned with geographical boundaries, such as a behemoth database at a headquarters site and smaller databases at regional offices.
- Two different databases may be required to access the same data in different ways, such as an order entry database whose transactions are aggregated and analyzed in a data warehouse.
- A busy Internet commerce site may create multiple copies of the same database to attain horizontal scalability.
- A copy of a production database may be created to serve as a development test bed.
