• New database option – CONTAINMENT • Only option supported in Denali is PARTIAL meaning, non-enforaced containment • Partially contained databases solve problems related to: • Logins: Database Users with passwords or mapped directly to Windows principles • System Collation: Temp tables use the database’s collation • sys.dm_db_uncontained_entities will display all potential containment breachesTobias Ternstrom @Pass Summit 2010 –http://sqlpass.eventpoint.com/topic/details/DBA346M

FileTable• A merging of the FILESTREAM and HierarchyID• Can store files and folders• FileTables are accessed via windows share• Created table has predefined schemaCREATE TABLE DocumentStore AS FileTableWITH FileTable_Directory Document FILESTREAM_ON FILESTREAMGroup1;

SEQUENCE• Generates a predicatble number of values• Global• Can be ascending, descending, minimum, maximum and cycle• Supports getting a range via sp_sequence_get_range

Several improvements over existing HA/DR• Multi-database failover• Multiple secondaries• Mirrors can be queried• Group databases to allow them to failover together• Needs Server 2008 R2 with Failover Clustering

Availability Group • Defines the high availability requirements • Databases, Replicas, Availability Mode, Failover Mode etc. Availability Replica • SQL Server Instances that are part of the availability group which hosts the physical copy of the database • Role: Primary, Secondary, Resolving Availability Database • SQL Server database that is part of an availability group • This can be a regular database or contained databaseGopal Askok @Pass Summit 2010 –http://sqlpass.eventpoint.com/topic/details/DBA351M

• Cloud-based SQL Server monitoring tool• Can monitor SQL Server 2008 and up• This secure cloud service will help DBAs to • Proactively avoid problems ongoing monitoring and alerting of configuration from the cloud • Reduce downtime and improve performance proactive scanning for known configuration issues and comparison with best practices • Resolve issues faster ability to get a current view of your configuration, changes that have been made, and use the most up to date solutions to solve them

• Web based tool that is used to cleanse data• Rules based on a user defined knowledge base• SSIS component• Zoomixs Accelerator software combines semantic and linguistic analysis with machine learning to classify, match and standardize complex corporate data

Knowledge • Creating and managing the Data Quality Management Knowledge Bases (DQKBs) & Reference • Exploration and integration with 3rd party reference data Data Cleansing & • Correction, de-duplication and standardization of the data Matching • Tools to monitor and control data qualityAdministration processesDenise Draper @Pass Summit 2010 - http://sqlpass.eventpoint.com/topic/details/BIA283M

A DQKB contains Data domains – containing all information related to a specific data type (name, city, state, postcode, id number…). Each domain stores all identified values, rules and 3rd party reference data that are relevant to this data domain. Matching policy – a set of rules that defines the matching computationDomains can originate from one of two sources Pre-Packaged Knowledge – a set of out-of-the-box data domains that will enable organizations an easy to use friction free starting point for their DQ work User-Generated Knowledge - organizations will be able to build and manage the DQKB knowledge from samples of their business data, or by the data steward using the DQS client.Denise Draper @Pass Summit 2010http://sqlpass.eventpoint.com/topic/details/BIA283M

The cleansing process classifies data into 4categories• Correct• Corrected• Not Corrected• Auto SuggestedCompleteness Accuracy Conformity Consistency

Integration Services catalog is the centralstorage and administration point forIntegration Services projects, packages,parameters, and environmentsThere is only one catalog, a user databasenamed SSISDB, on an instance of SQLServer

Enabling CLR IntegrationCreate Catalog dialog box you will be askedto supply a password. This password isused to create a database master key. Thedatabase master key is used to encryptsensitive data in the catalog.Sensitive Parameter Value EncryptionOperations CleanupProject Version Cleanup

• PowerPivot in SQL Server• An index is created across columns instead of rows• Can give a massive query performance increase• Read only• Reduced IO• Compressed• Not a NoSQL implementation / alternative

Denali introduces a new type of index called thecolumnstore.This new type of index is built up on the valuesacross columns instead of traditional row basedindexes.As data tends to be less unique across a column itallows the columnstore to efficiently compress andstore data.

The columnstore is currently read-only, however itcan be updated via dropping and recreating theindex, or switching in a partition. Due to the ability to compress and keep the indexin memory the Columnstore can give massive(10x, 100x, 1000x…) increase in speed towarehouse queriesNot all queries can benefit and some can regress.In general typical star join queries found in a DataWarehouse when only a portion of the columnsare selected will get the biggest benefit.

• Analysis Services is perceived to be “too complicated”• Can be in either one of two modes • VertiPaq engine is used to store data locally in Relational tables • Real-time• Uses Column Store for huge performance gains• DAX expression language• Does not replace UDM• Can author in Excel or BIDS (VS 2010)• Can be hosted by Analysis Services

Web-based reporting experience that offersrich visualization to let you project the storyabout your data to end users and otherbusiness users

New data visualization experience coming inthe SQL "Denali".Project Crescent allows business users tomanage data and show information visualize, interact and report on data using highly interactive visualizations, animations and smart queryingMost exciting features is its integration withPowerPoint

• Self service BI / ad-hoc reporting• Based on BISM• Hosted in SharePoint 2010 with SSRS and SSAS integration• Easily export to PowerPoint

Through a feature called Storyboarding,users can embed reports in PowerPoint andmanipulate the live data during apresentationThe first public CTP for Project “Crescent” iscurrently planned for the first half ofcalendar year 2011

When to use what? • Depends on the complexity of the app • Use UDM for multidimensional modeling, complex calculations, scoped assignments, calc members, custom rollups, etc. • For everything else, BISM offers a simpler and high performance alternative Existing BI solutions • Stick with UDM… • Consider BISM if you’re planning a major solution upgrade • Migration from UDM to BISM will require some redesign BISM and UDM are available side-by-side • Instance level choiceChris Webb @Pass Summit 2010 - http://sqlpass.eventpoint.com/topic/details/BIA412
