Agenda Overview

Tools to develop Data Tier ApplicationsData Application ComponentsWhere do we put the DACWhat’s in the Data Tier ApplicationComparing DACs with Database projectsLimitations of object supported in V1DAC and UCP’sDemo’s (SSMS & Visual Studio 2010)Q&A

Tools to Develop Data Tier Applications

You will need the following items

SQL Server 2008 R2

DAC Projects in Pro+ SKUs

Data-Tier Application Components

Single file filename.dacpac

Combines logical & Physical objects along with deployment policies

Simpler deployment options Install / Uninstall

/Upgrade Repair (in future release) filename.dacpa

c

Policies

Logical

Physical

Where do we put the DAC

Data-tier applications are deployed to a database instance (or multiple instances)

SQL Server 2008 R2

But otherwise are the same as other user Databases

What’s in the Data-Tier Application

.dacpacs are a zip file, containing multiple XML files

Database object definitionsServer-selection policiesApplication properties (versions, App name…)Instance-level objects (logins, users...)pre & post-deployment scripts

Current version has limitations of objects supported

DAC vs Database Projects?

Database projects and Data-tier Application projects can operate side by side

Database Projects Data-Tier Application Projects

Target applications Mission or business critical Departmental sized (< 20GB)

SQL Server object types

All SQL Server objects Only certain SQL Server objects currently supported in Version 1

Database support SQL Server 2005, 2008 & 2008 R2 and third-party databases

SQL Server 2008 R2 (Supported on SQL Server 2008 SP2)

Upgrade(schema + data)

Deploy generates SQL scripts;data stays in place

Upgrade is automated;data is migrated (Dependent)

Before .dacpacs development was done in various different methodsSometimes this is a database project, below is a quick comparison of the differences where a database project or DAC are the most suitable method

DAC V1 Limitations (Objects Not Supported)

Objects marked for deprecation(Including defaults, rules and numbered stored procedures)

CLR objects and data types (Spatial, Geography, Geometry, Hierarchy ID data types, SQL assemblies, CLR stored procedures and functions)

User-defined aggregates and user-defined (CLR) types

Partition schemes and partition functions

XML schema collections, XML indexes and spatial indexes

Service broker objects Filestream columns

Symmetric keys, asymmetric keys, certificates

DDL triggers Application roles Full-text catalog objects Extended stored procedures Encrypted objects

(Encrypted stored procedures, views, functions, and triggers)

Objects containing cross-database dependencies and linked server references

Extended properties Synonyms

DACPAC & UCP’S

DBA

SQL Server Management Studio

Install the .dacpac & monitor it’s usage via a UCP

Utility Explorer content has useful Videos to help you with UCP’s

DEMO TIMESeveral demo’s now will follow in SSMS & Visual Studio 2010 to illustrate the concepts

• Demo 1 SSMS Extracting a Database as .dacpac

• Demo 2 Visual Studio 2010 - DACPAC project

• Demo 3 SSMS Installing / Upgrading DAC databases

Latest News - (SQL Server 2008 SP2) Released 29th Sept 2010

SQL Server 2008 R2 Application and Multi-Server Management Compatibility with SQL Server 2008.

SQL Server 2008 Instance Management.With SP2 applied, an instance of the SQL Server 2008 Database Engine can be enrolled with a SQL Server 2008 R2 Utility Control Point as a managed instance of SQL Server.

Data-tier Application (DAC) Support.Instances of the SQL Server 2008 Database Engine support all DAC operations delivered in SQL Server 2008 R2 after SP2 has been applied.

You can deploy, upgrade, register, extract, and delete DACs. SP2 does not upgrade the SQL Server 2008 client tools to support DACs.

You must use the SQL Server 2008 R2 client tools, such as SQL Server Management Studio, to perform DAC operations.

Action steps give useful insight to how a DAC upgrade is performed

Creating a new version of the Database and renaming previous versions
