What’s R2 CTP 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.

This public preview offers the opportunity to experience early, pre-release feature capabilities including: - Application and Multi-server Management - SMP scale up with support for up to 256 logical processors.- Report Builder 3.0 with support for geospatial visualization

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.

Scalability & Performance Enhancements

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.

Contd…

How Unicode Compression affects Data Storage

You can implement it simply when creating table: with(Data_Compression=ROW)

or after creating table: Alter Table [Name] REBUILD WITH(Data_Compression=ROW)

demo..

Locale Compression Percent

English 50%

German 50%

Hindi 50%

Turkish 48%

Vietnamese 39%

Japanese 15%

Manageability Enhancements

SQL Server 2008 R2 introduces the SQL Server Utility for managing multiple instances of the SQL Server Database Engine. 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.

Here are some features enhancements in manageability :

SQL Server utility

Data-Tier Application

SQL Server PowerShell Provider

SQL Server Utility Creating a SQL Server UCP: Install a

single instance of SQL Server 2008 R2 database engine and then promote it to be the UCP.

Enroll Instances in UCP Setting Central Policies Using the Utility Explorer to display a

dashboard, for all enrolled instances.

Data-Tier Application

A DAC defines all of the Database Engine schema and instance objects, such as tables, views, and logins, required to support the application. The DAC operates as a single unit of management through the development, deployment, and management lifecycle of the associated application. The DAC also contains policies that define the deployment prerequisites for the DAC.

Create a DAC package :- You can create a DAC package by simply expand database tree go to database then tasks and click on “Extract Data Tier Application”.

Deploy a DAC Package :- Again in SSMS expand Management tab then go to Data-Tier Applications right click on it and choose “Deploy Data-Tier application”.

SQL Server PowerShell Provider

SQL Server 2008 R2 introduces new SQLSERVER:\Utility and SQLSERVER:\DAC folders to support the SQL Server Utility and data-tier applications in PowerShell scripts.

What’s New In Reporting Services

Report Builder 3.0 Map & Spatial Data Visualization ATOM Data Feeds Report Manager RDL Expression Language Enhancements

Report Builder 3.0

It provides a better preview experience.

Dataset results are cached when connected to a report server, which speeds up making layout changes and previewing the new report.

Maps & Spatial Data Visualization

Report designer provides a Map Wizard & Map Layer Wizard to add maps & map layers to your report.

Maps can integrate ESRI shape files, as well as directly integrate with Bing Maps.

DEMO

Atom Data Feeds

Reports are now also available in the ATOM standard complaint format that can be consumed by GEMINI and other tools.

You can export a production report as a data feed or you can create a report whose primary purpose is provide data, in the form of data feeds, to applications.

Report Manager

Report Manager has been updated in this release to provide a better user experience, and an improved look and feel.

Allowing more room for Report Viewer when rendering reports.

An updated Report Viewer toolbar, which includes some updates to the toolbar controls, as well as the ability to export report data to an Atom service document and data feeds.

RDL Expression Language Enhancements

Enhancements in RDL

Direct Geo Spatial Data Three Lookup Functions

- Lookup Function- LookupSet Function- Multilookup Function

Contd..

Lookup Function - This is a much awaited function developers looking for. This gives you the opportunity to join 2 datasets . Here the syntax for Lookup Functions

=Lookup(Source_exp, destination_exp, result_exp, Dataset)

Ex : We have two datasets “A” and “B” Then we have to get Name field from dataset “B” where id filed of dataset “A” matches storeid filed of dataset “B”. So here we can achieve it..

=Lookup(Fields!ID.Value, Fields!StoreId.Value, Fields!Name.Value, “B")

Multiple lookup Functions :- Returns the set of first-match values for the specified set of names from a dataset that contains name/value pairs.- Same as lookup Function but use in this type of scenarios :

Ex: If we have a comma separated column “custlist” in a dataset and on other dataset we have “custid” with “custname” and we want “custname” on basis of custid then we do some thing like this

=Join(MultiLookup(Split(Fields!custlist.Value,","), Fields!custid.Value,Fields!custname.Value,“DsNm")), ", ")

Lookup Set Function- It returns a set of matching values for the specified name from a dataset that contain name/value pair.

Lookup(source_expression, destination_expression, result_expression, dataset)
