1. An Investigation into Database Farming for Improved Performance Presented by: Supervisor: Russell Yong Prof Peter Wentworth

2. Quick Recap Databases used in major corporations require: Expensive software (Oracle, IBM, SAP) Tremendous amounts of hardware is needed to produce acceptable performance levels

3. Quick Recap Use a less expensive hardware and software (SQL Server 2000) Use tried and tested techniques (Back-end server farming) To produce a high-performance web-service (Disconnected data model)

4. Dataset http requests Web-server Farm of databasesWeb service Disconnected Clients

5. Problems Course Work.NET’s Threading Problem Queries are hard coded Demonstration <-.NET ‘gods’ Demonstration

6. Progression Queries from multiple sources simultaneously (Generic class) Time saving (primitive timing) Elegant recovery from exceptions

7. Where to from here? Implement as a web service Get hold of a big enough test database – perhaps with performance issues User definable queries

8. Where to from here? Decide on a query strategy Start performance tests Benchmarks Investigate various performance enhancing configurations
