  1. Development Life Cycle using Visual Studio Team Edition for DB Professionals Richard FennellEngineering DirectorSQLBits II Birmingham 1st March 2008

  2. Agenda • Why do we need DB Pro.? • What is Visual Studio Team System • DB Pro. Features • Project Life-cycle • Testing • Deployment • Power Tools

  3. 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

  4. Excel Project Team System Web Access Operations, QA and Help Desk Non-Microsoft Developer Visual Studio Team SystemApplication Life Cycle Management (ALM) Solution

  5. 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.

  6. DB Pro provides support for the fulldatabase lifecycle

  7. 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

  8. DBPro Features • Database Unit Testing • Leverages the existing Test Project Infrastructure • Supports data generation • Build and Deployment • MSBuild and Team Build integration

  9. 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

  10. 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

  11. Roles in a DB Project Writes Tests Writes DB Code Refactors Runs Tests Checks In Works with other developers to integrate Creates New DB Project Reverse Engineers DB to Project Creates Data Generation Plan Reviews Changes Compares Updates to Production Builds Deploy Package Deploys to Production Manage Develop Deploy DB Administrator DB Developer DB Administrator

  13.

  16. demo DB Life Cycle

  17. So what DBs did I end up with? VS Dev DB Live DB Local Test DB Live production DB You may also have a test 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)

  18. 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.....

  19. demo Data Generation

  20. 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

  21. 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

  22. 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

  23. 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
