Development Life Cycle using Visual Studio Team Edition for DB
Professionals
Richard FennellEngineering Director
SQLBits II Birmingham 1st March 2008
Agenda
• Why do we need DB Pro.?• What is Visual Studio Team System• DB Pro. Features
– Project Life-cycle– Testing– Deployment– Power Tools
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 standard way to manage the DB – until now

Visual Studio for Database Professionals
• Was known as ‘DataDude’ in beta phase• Came out in 2006, a year after the main VS
2005 release.• New release VS 2008 is really more of a
service pack than a major release.
DB Pro provides support for the fulldatabase lifecycle
DBPro Features• Incorporates the Database Professional into the
software development lifecycle • Provides a foundation for change management
and process integration• Exposes database schema as individual script files• Provides a set of essential tools
– Version Control via Visual Studio supported providers– Rename Refactoring– Schema Comparison Tools– Data Comparison Tools
DBPro Features
• Database Unit Testing– Leverages the existing Test Project Infrastructure – Supports data generation
• Build and Deployment– MSBuild and Team Build integration
Power Tools
• Power Tools add additional features that didn’t make the product release cycle– Dependency Viewer – New Refactorings– Data Generation Wizard– MSBuild Tasks – T-SQL Static Code Analysis – Schema Manager API
Team Foundation Server Integration
• As a member of the Visual Studio Team System family, DBPro is integrated with all of the team features
• TFS provides– Team project with prescriptive guidance– Version control management– Work Item tracking– Team Build integration

DB Life CycleDB Life Cycle
So what DBs did I end up with?
Live DB VS Dev DB Local Test DB
Live production DB
You may also have atest or staging DB
DB Created by Visual Studio
Used by IDE for design time validation
Developers Test DB
Used for sandbox testing
(might be shared)
Data Generation
• Shipped with the product– Data-bound, Regular Expression, Random Number
• Available as a Power Tool– File-bound and a Wizard tools to ease the process
• Codeplex – DbProGenerators– Lorem Ipsum, soon XML bound, Word bound and
web search bound
• Plus what you write yourself.....

Testing in DB Pro
• Firstly remember that can test any CLR code before loading it into SQL Server
• DBPro adds database tests that can be used to test any stored procedure, function, trigger or DB object
• A single test project can contain a variety of test types
• Can be used to auto generate test stubs
Is DB Testing Valid?
• But 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
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
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
