CASE STUDY 4 – A Heterogeneous Federation of Databases
Exploiting the Architecture of Objectivity/DB
Objectivity/DB provides a Single Logical View by storing objects within databases in a Federated Database. The Objectivity/DB Storage Manager currently manages and structures all of the databases. However, it would be feasible to add a Legacy DBMS Gateway to the architecture. This gateway could use ODBC, or possibly middleware such as Oracle’s Toplink, to service requests made by the Object Manager.
The advantages of this approach are:
- Data remains under the control of the existing systems.
- Object Oriented applications use a single API to access heterogeneous data sources.
- Frequently traversed objects and relationships can be repre sented by proxies within Objectivity/DB. This eliminates the cost of expensive join operations.
Coupling Objectivity/DB with a parallel, RAM-based data mining tool could significantly speed up complex searches across large datasets, effectively solving the “Needle in a haystack” problem.
