Agenda

• What is DAC• Live demo• Utility Control Point• Q&A• Summary

Challenges

Development

• No uniform DB project system and workflow

Deployment

• DBAs and Developers work in silos

• Time consuming and error prone

Management

• Difficult to centrally control the environment

InvestmentsDevelopment

• Data-tier Application project• Integrated editor, debugger,

IntelliSense, policy designer• Static code analysis, build

service

Deployment

• Easier to deploy and upgrade Data-tier Apps from VS and SSMS

Management

• Manage @ Scale: SQL Server Control Point

• Visualize resource utilization at the instance & application level

Concepts - Data-tier Application Project

• New project type in VS 2010; Leverages Database project system code base

• First class T-SQL/DAC development experience in Visual Studio

Concepts• .dacpac = unit of deployment

(data-tier application + developer intent)

• Data-tier Application Component• Improves collaboration

between developer and DBA• Moves developers from a

procedural model to a declarative model

• V1 is targeted at small apps
