Transcript Executive Summary

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
Federated Systems
DB2 / Web Sphere Federated DB
 Why DB2?
 Other choices? Oracle?
 http://www.oracle.com/technology/products/middlewa
re/index.html
 SQL Server?
Web Sphere Federated Server
Setup of Federation Database
Special Interest Activity Federated
Server Setup
 Wrappers
 User mappings
 Nicknames
Special Interest Activity Setup
 IBM DB2-C
 IBM DB2 EE (Extended Edition)
 IBM Web Sphere Federated Server
 Federated Object Setup
Final Architecture
Data Sources for the Special
Interest Activity
 SQL Server, Oracle, DB2
 Excel
 XML
Setting up Each Data Source
 SQL Server
 Oracle
 DB2
 Excel
 XML
Wrappers
Outcome of Object Usage
 Querying Tool - Command Center
 SQL Statements - Command Center of DB2
 Program to ITK478
 Crystal Reporting
 Uses Views
Demo
 VPN over wireless may be slow
 Review what’s been done
 Add another data source
Demo
 Program Source
 Crystal Problem
Learning Curve
 Product selection
 Database access
 File access
 Focused on simple tasks
 Viable system up and running
 Simple data source
 Many more issues and components would come into
play for a ‘real-world’ system and were not addressed
in this SIA
