Federated Database Set Up Greg Magsamen ITK478 SIA

Proposed Deliverables Federated Database and multiple heterogeneous databases and data sources (Excel, XML) accessed via the federated database. Sample SQL Statements via some SQL Query Tool or Reporting Tool. Possibly a program extracting data from data source (Net Beans, VS 2005 (.Net) Reporting Tool (Crystal or Business Objects)

Agenda Database Middleware Federated Systems DB2 and WFS Setup Demo Conclusions

Not Covered Complex situations Data Mappings, Function Mappings Various types of data sources

Purpose Discover the Architecture What software do I need? How do I set it up? Is this easy, difficult? How viable for a real world implementation?

Database Oriented Middleware What is Database Oriented Middleware? An interface to an application The ability to convert the application language into something understandable to the target database The ability to send a query to a database over the network The ability to process a query on the target database The ability to move a response set back over the network to the requesting application The ability to convert a response set into a format understandable by the requesting application
