Overview of SQL Server 2008 Major Enhancements from SQL Server 2008 to SQL Server 2008 R2

SQL Server 2008 is a very powerful tool of Microsoft. SQL Server 2008 comes up with many enhancements in Security, Availability, Performance, Management, Storage, Programmability, BI( Business Intelligence ) and SSRS (Reporting Services) .

New Editions 2 new premium editions to meet the needs of large scale datacenters and data warehouses New R2 Technologies Application and Multi-Server Management Managed Self-Service Business Intelligence Master Data Services StreamInsight Complex Event Processing Technology

New R2 Solutions PowerPivot for SharePoint PowerPivot for Excel Parallel Data Warehouse Fast Track Data Warehouse

Building on the momentum of SQL Server 2008, “R2” improves IT efficiency by reducing the time and cost of developing and managing applications Empowers end users to make better decisions through Self-Service Business Intelligence and enables organizations to scale with confidence by providing high levels of reliability, security and scalability for business critical applications.

Report Builder 3.0 with support for geospatial visualization Application and Multi-server Management - SMP scale up with support for up to 256 logical processors. This CTP provides the first opportunity to explore some of the features of SQL Server 2008 R2 and see how it all comes together to enhance performance and scalability, enable self-service BI and improve IT and developer efficiency.

SQL Server 2008 R2 comes up with two new feature in scalability and performance enhancements: Support for More Than 64 CPUs- The number of CPU cores that a server can use for database operations been increased from 64 to 512. Unicode Compression-Unicode data that is stored in nvarchar(n) and nchar(n) columns is now compressed by using an implementation of the standard Compression Scheme for Unicode(SCSU) algorithm.

Datacenter Designed to deliver a high-performing data platform that provides the highest levels of scalability for large application workloads, virtualization and consolidation Key features new to Datacenter: Application and Multi-Server Management for enrolling, gaining insights and managing over 25 instances

High-scale complex event processing with SQL Server StreamInsight Supports more processors and up to 256 logical processors for highest levels of scale Supports memory limits up to OS maximum

SQL Server 2008 R2 Parallel Data Warehouse is a highly scalable data warehouse appliance-based solution

Key features new to Parallel Data Warehouse: 10s to 100s TBs enabled by MPP architecture Advanced data warehousing capabilities like Star Join Queries and Change Data Capture Integration with SSIS, SSRS, and SSAS Supports industry standard data warehousing hub and spoke architecture and parallel database copy

 Pre-configured For Each SQL Server Instance On Each Compute Node.  Drives Configured As RAID1 To Avoid Appliance Failover for a Single Drive Failure  IBM Compute Nodes Will Have 1 Lun (1 RAID1 Pair)  Dell Compute Nodes Will Have 2 Lun’s (2 RAID1 Pairs)  HP Compute Nodes Will Have 3 Luns’s (3 RAID1 Pairs)  Tempdb:  Sort-work Area For Data Loading Into Clustered Index Tables  Spill Area For Hash Joins Not Fitting Into Memory

Pre-configured 4 RAID10 Pairs for Primary User Data 1 RAID10 Pair for Database Logs 2 LUN’s Are Spread Across Each RAID Pair User Databases Are Separate Physical SQLServer Databases Staging Database (Optional) Used for Loading and to Minimize Fragmentation

You can implement it simply when creating table: With (Data_Compression=ROW) or after creating table: Alter Table [Name] REBUILD WITH(Data_Compression=ROW)

SQL Server 2008 R2 introduces the SQL Server Utility for managing multiple instances of the SQL Server Database Engine. In SQL Server Management Studio, organizations will gain insights into their growing applications and SQL Server instances

Consolidation management Use a new explorer in SQL Server Management Studio to access the central management for multi-server management and at-a-glance dashboard views Improve service levels Set policies to define desired utilization thresholds across target servers or applications within a new central management point. Identify issues with instances and applications

It also introduces a unit of management called a data-tier application that provides an application-based view for managing the data-tier objects in the SQL Server Utility or stand-alone instances of the Database Engine. R2 makes it easier for DBAs to move databases around from server to server in much the same way virtualization admins move guest OS’s around between physical hosts.

SQL Server 2008 R2 still has the same concept of databases, but it’s added a new level above databases called Data-Tier Applications, abbreviated DAC The DAC includes the database schema plus some server-level objects required in order to support the database, like logins. The DAC does not include the data inside your database.

For deployment best practices, you should have any necessary data (configuration tables, basic lookup tables) already scripted out as part of your deployment strategy. With the DAC approach, it makes sense to put these scripts inside the database as objects. For example, you might have a stored procedure called usp_deploy that populates all of the necessary configuration tables via insert statements.

Developers create and update their database schema, stored procedures, functions, etc. inside Visual Studio, packaging them into DAC Packs, and handing them to the database administrator.

SQL Server installs by creating sysprep-ed images of SQL Server standalone instances that can be copied and quickly installed on target systems. Enables rapid provisioning and configuration using prepared images stored in VHDMart for Hyper-V deployments.

SQL Server 2008 Sysprep accomplishes the install in two phases behind the scenes: prepare and configure. In SQL Server 2008 R2, two new SQL Server setup actions are exposed to the users: PrepareImage (also referred to as “prepare”) and CompleteImage (also referred to as “complete” or “configure”).

SQL Server PrepareImage takes about 30 minutes for Engine and RS components, whereas CompleteImage takes a few minutes. Windows SysPrep process can be run in between the two steps to create Windows OS image and deploy to target computers, but is not a required step. These two steps can be run back-to-back on the same computer. Sysprep will be able to save on the average an estimated 30 minutes per install.

Empower your business units and users to create and share BI solutions through familiar and intuitive tools SQL Server PowerPivot Add-in for Excel(formerly known as "Gemini) SharePoint 2010 based Operations Dashboard SQL Server Reporting Services Report Builder 3.0 Rich visualization of geospatial data

So, what is PowerPivot then? New client and server components for self- service, managed BI Client component lights up Excel 2010 Huge data capacities and mash-ups In-memory SSAS data model Server component lights up in SharePoint 2010 Integrated SSAS service to handle data models Excel Services used to render spreadsheets

PowerPivot client tool Add-in for Excel 2010 Provides SSAS engine, PowerPivot UI Creates in-memory database model Gather data for analysis Load & Prepare Data option Connect to data sources (lots of options) Import data into PowerPivot tab Select columns, filter data as needed

Describe how data is related Inform PowerPivot of data relationships Supports basic PK-FK type relationships Create basic data model Use expressions (DAX) to add calculations Includes many Excel functions Expressions based on columns, not cells

Use pivot-tables and pivot-charts Updated task pane for selecting data Data elements grouped by PowerPivot tab Use as dimensions or measures as appropriate New and updated visualizations Slicers (excellent!) Sparklines (excellent!) Improved icon sets, data bar formatting Improved chart options and performance

Master Data Services helps enterprises standardize the data people rely on to make critical business decisions. With Master Data Services, IT organizations can centrally manage critical data assets companywide and across diverse systems, enable more people to securely manage master data directly, and ensure the integrity of information over time.

Master Data Services is a Master Data Management application that consists of the following components and tools Master Data Services Configuration Manager, Master Data Manager Master Data Services Web service

Master data hub that provides central management of master data entities and hierarchies and collections Thin-client stewardship portal that provides secure, role-based Web access to master data Versioning of all data entities and hierarchies Human workflow that notifies assigned owners by e-mail of business rule violations

Flexible and extensible business rules that safeguard the quality of data entered in the master data hub Support for a broad range of hierarchy and attribute management strategies and requirements Comprehensive role-based security model that enables fine-grained, secure access to master data

Models are the highest level of data organization in Master Data Services Entities Attributes and attribute groups Hierarchies (derived and explicit) Collections

Data volumes are exploding with event data streaming from sources such as RFID, sensors and web logs The size and frequency of the data make it challenging to store for data mining and analysis. The ability to monitor, analyze and take business decisions in near real-time
