DATABASE DEVELOPMENT WITH VSTS DATABASE EDITION By Chris Dahlberg ©2009 Aspect Software, Inc. All rights reserved. 1

2 “Legacy” Database Development  Difficult to implement change management Full database backups CREATE/ALTER scripts  Difficult for offline development  Difficult to integrate into ALM Lack of proper versioning tools Lack of formal testing tools

The Solution: Database Development Life Cycle  Database development in Visual Studio Include databases in Visual Studio solution  Source Code Control (SCC) Let the developer declare database schema The tools figure out how to create/modify the database  Simplified Deployment  Code Analysis  Refactoring  Unit Testing  Build automation

2008 Database Data Generation Plan  Creating Databound Data Generation Plans for large database schemas was a sizable upfront investment: Each field had to be configured to use sequential databound generators Each data bound generator required a connection to a database Could not easily include data from existing databases for all tables and then customize as needed

Database project types Database Project Available for SQL Server 2005 and SQL Server 2008 Defines a user database Supports all objects implemented by the respective SQL Server version Server Project Available for SQL Server 2005 and SQL Server 2008 Defines server-level objects and modifications to the SQL master database Examples of server-level objects are logins and custom error messages Data-tier Application Component Defines databases that will be deployed to SQL Server Utilities A DAC is a self-contained unit of management that defines and bundles database objects and SQL Server instance objects that are associated with the database and deployment requirements
