Introduction

Data platform vision in SQL Server 2008 will help organizations to create next generation data driven applications.

Key areas supporting the data platform vision: Mission-critical enterprise data platform Dynamic development Relational data Business intelligence

Enhancements in SQL Server Management Studio improve performance and help to develop applications faster.


Data Platform Vision 1-3

Data platform is: Secure Manageable Reliable for creating critical applications



Data Platform Vision



SQL Server 2008 targets four major areas:

Enterprise Data Platform

Dynamic Development

Pervasive Business Insight

Beyond Relational Data


Location Intelligence

Spatial data capabilities help in building location-aware applications, such as applications for Global Positioning System (GPS) devices.


Spatial Data Types

geometry geography

Used to create objects representing a flat plane with x and y coordinates for points traced on edgesof polygons, lines, and so forth

Uses latitude and longitude angles to find the points on the earth

SQL Server 2008 introduces spatial data types, using which developers can easily develop location-aware applications in SQL.


Support for any type of data 1-3

SQL Server 2008 is capable of handling and storing data from diverse sources

SQL Server 2008

Data Source 1

Data Source 4Data Source 2

Data Source 3XMLADO.NET

Files CollectionsSpatial Data

. . .



FILESTREAM data Used for storing Binary Large Objects (BLOBs) in the

form of files

Integrated Full-Text Search Helps in faster searching of documents and textual

data

Provides advantages over alternatives such as LIKE predicate with wildcards or custom-built solutions



Large User-Defined Types (UDTs) Used for storing spatial data like geometry and geography objects

If SqlUserDefinedTypeAttribute.MaxByteSize is set to -1, the UDT can store data upto 2 GB, otherwise cannot exceed the size specified in MaxByteSize property.


Occasionally Connected Systems

SQL Server and .NET Framework 3.5 help to develop cache-based and notification-based applications.

Databases are accessible in mobile applications and then synchronized seamlessly with the server whenever reconnected.


Pervasive Insight

Enhancements to SQL Server Analysis Services, Integration Services, Reporting Services, and data warehousing.

SQL Server 2008 has driven business intelligence (BI) in organizations by providing enhancements in data warehousing such as:

Improvements in SQL Server Integration Services (SSIS) Block Computations Scalable Reporting Internet Report Deployment Manage the Reporting Infrastructure


Analysis Services

Improved multidimensional query performance

Enhancements contribute to improved data analysis, Online Analytical Processing (OLAP)

Multidimensional expression queries - used to query multidimensional objects and return multidimensional cellsets

Enhancements in SQL Server Analysis Services: Attribute Relationship Design MOLAP Write back Block Computation Star Join Query Optimization


Integration Services

Plays an important role in Extract, Transform, and Load (ETL) operations

Consists of 28 control flow tasks and 11 maintenance plans in SQL Server 2008

Some of these tasks are: Container Tasks Data Preparation Tasks SQL Tasks Maintenance Tasks


Reporting Services

Enhancements to improve visualization and delivery of data, simplify deployment and configuration of reports

Some enhanced features are: Managed Reporting Ad-Hoc Reporting Report Designer Report Builder Compelling Reports


Enhancements in Management Studio

The new IntelliSense feature of SQL Server 2008 is comprised of following characteristics: Speeds up application development by providing

syntax and online references in the code Monitors code typed in the code editor region and

prompts with the syntax help Saves time for the developer because it provides

syntax help, word completion, and so forth Can be activated or deactivated from the menu by

selecting Query -> IntelliSense option


Multi-Server Query

Enables to query multiple servers from one query window

Procedure: Each server must be registered in the SQL Server

Management Studio local servers group After all servers are registered, right-click on the group and

choose new query option When multiple servers are connected, the confirmation is

displayed at the bottom of window There can be a mixture of SQL Server 2000, SQL

Server 2005, and SQL Server 2008 within a local servers group


Query Editor Regions

Help to simplify working with large amount of Transact-SQL code Is applicable only to multi-line statements Is new in SQL Server Management Studio Can be collapsed as well as expanded by clicking the ‘-’ or ‘+’ sign

besides them Regions defined by following hierarchy:

From first GO command to next GO command Statements between BEGIN – END, BEGIN TRY – END TRY, BEGIN CATCH – END CATCH

Multi-line statements


Advanced Object Explorer

Object Explorer Details option:

Enables to view several details about database and server objects

Presents information about all the objects in the server in a tabular format

Sorting, filtering can be done on the columns


Search Feature

New feature introduced in Object Explorer Details window

Enables you to search server and database objects

Can search for different types of objects, such as tables, stored procedures, and so forth

The searched result is displayed in the same window as Object Explorer Details

Everything displayed in the Object Explorer details screen can be copied and pasted to Excel without any formatting issue


Activity Monitor

Feature that gives information about SQL Server processes

Many changes implemented in Activity Monitor of SQL Server 2008

Represented as a tabbed structure


Overview

Is the first tab in the Activity Monitor Is expanded by default Comprises of a pane showing the graphical

display of instance information such as processor time, waiting tasks, database I/O, and batch requests


Processes

Displays information for active user connections Information displayed can be rearranged, sorted,

or filtered


Resource Waits

Displays information about waits for resources for the SQL Server instance, including wait time and wait category


Data File I/O

Displays I/O activity for relational database files within the Database Engine

Includes both the system and user databases


Resource Expensive Query

Shows information about the most expensive queries over the last 30 seconds


Summary

SQL Server 2008 includes several new features and architectural enhancements.

Enterprise data platform, support for beyond relational data, and changes in SQL Server Analysis Services are some of the new features and architectural enhancements.

Enhancements have also been made to SQL Server Integration Services and SQL Server Reporting Services.

The enhancements in SQL Server 2008 Management Studio include IntelliSense support, Query Editor regions, Multi-Server query, Object Explorer Details, and Activity Monitor.
