Data Tier Applications (DAC)

• Defines all of the Database Engine schema and instance objects

• A single unit of management • Simplifies development, deployment, and management

lifecycle• Contains policies that define the deployment

Performance Enhancements

T-SQL Performance Enhancements

MERGE and GROUPING SETS improvementsLess scans through table

Table-valued parameters improvementsLess round trips to database

Improvements for data warehouse queriesEarlier predicate filteringMultiple bitmap iterators per query

Plan Guide ImprovementsEasier to create plan guidesPlan guides on DML statements

Also: Object reference tracking makes schema and procedural code versioning less error-prone

Better T-SQL

Other Data type enhancements

Better Data types

Entity Framework

What is EF?Object/Relational Mapping (ORM) framework

How to use EFissue queries using LINQthen retrieve and manipulate data as strongly typed objectsLINQ to Entities provides IntelliSense and compile-time syntax validation for writing queries against a conceptual model

Why use EF?enables you to work with relational data as domain-specific objects eliminates the need for most of the data access plumbing code that you previously wrote

•New or Improved Dynamic Management Views --sys.dm_exec_query_stats --additional columns (long-running queries)--new DMVs and XEvents on select performance counters are introduced to monitor OS configurations/resource conditions related to the SQL Server instance

•Improved FORCESEEK index hint & New FORCESCAN query hint --syntax modified w/optional parameters allowing it to control the access method on the index even further--FORCESCAN complements the FORCESEEK hint allowing specifying ‘scan’ as the access method to the index

•Improved DACPAC - (DAC Fx) improved database upgrades: --(DAC) Framework v1.1 and DAC upgrade wizard enable the new in-place upgrade service --New in-place upgrade service will upgrade the schema for an existing database in SQL Azure and the versions of SQL Server supported by DAC

•New Disk space control for PowerPivot: --Introduces two new configuration settings that let you determine how long cached data stays in the system
