Agenda
• Why do we need DB Pro.?• What is Visual Studio Team System• DB Pro. Features
– Project Life-cycle– Testing– Deployment– Power Tools
• The Future
blackmarble
Pain points in DB development
• What is the ‘correct DB schema’?• How do we version control it?• How do I know the impact of a change?• How do we publish a DB?• Where do we get test data from?• How do we test it anyway?
• There has been no ‘Microsoft standard’ way to manage the DB – until now

Is DB Testing Valid?
• You have to ask how useful it is to test at the raw data layer?
• Usually more effective to test the DB via the data access layer or as part of integration testing
blackmarble
MSBuild
• All the key DB tasks can be scripted
• Database operations can become part of a scheduled build
• However this can all get a bit complex and DBPro MSBuild tasks are a bit idiosyncratic.
• Check the web for examples
blackmarble
The Future
• Developer & Database Team Editions merged
• Database Schema Providers– Publicly extensible in Visual Studio 2010
– Quest Software announced that they will offer a Database Schema Provider (DSP) for Oracle
– Partnership with IBM provides DB2 support
• Contextual Project Feature Extensibility– Publicly extensible in Visual Studio 2010
blackmarble
Summary
• Visual Studio Team Edition for Database Professionals make SQL development part of the project mainstream.
• Team System coupled with integrated version control helps to mitigate risks associated with DB schema change
• Build integration provides for quality tracking and improvement
• Process reduces last minute problems and the need to rollback changes out of production
