 SQL Server 2008 Analysis Services introduces a set of new, innovative Best Practice Design Alerts that provide automatic notification of potential design issues early in the development process, which reduces wasted time caused by design mistakes and facilitates a faster development process.

Scalable Infrastructure

 Analysis Services can scale to support databases of many terabytes

in size with many thousands of users

 SQL Server 2008 Analysis Services provides Dynamic Management Views similar to those available to the database engine

 AS can improve query performance by orders of magnitude and therefore allow a finer granularity of analysis.

Superior Performance

 SQL Server provides attribute-based hierarchies that avoid the need for any duplication and improve performance and scalability.

 SQL Server 2008 Analysis Services allows writeback data to be

stored in MOLAP format resulting in significantly better performance for query and writeback operations.

 AS prevent users from overloading the relational database by

providing a high performance, transparent, synchronized aggregate cache.

MS SQL Server 2008

Extend Solutions with Comprehensive Analytics

 Analysis Services takes the analytical platform to a new level offering more advanced features than those traditionally related to OLAP This enables organizations to accommodate multiple analytical needs within one solution offering so much more than a traditional OLAP platform In this effort, the

Unified Dimensional Model (UDM) plays a central role, providing extensive analytical capabilities

Central Manageability of Key Enterprise Metrics

MS SQL Server 2008

Unified Dimensional Model

 The UDM was a new concept for Analysis Services that was introduced with the release of SQL Server 2005 The UDM provides an intermediate logical layer between the physical relational database used as the data source and the proprietary cube and dimension structures that are used to resolve user queries

 In this way, you can think of the UDM as the centerpiece of the OLAP

solution

Central Manageability of Key Enterprise Metrics

 In SQL Server 2008 Analysis Services enterprise wide Key Performance Indicators (KPI’s) can be centrally stored and managed

 This provides a central repository for users to access key enterprise metrics through a variety of applications including Microsoft Office

PerformancePoint Server 2007, Microsoft Office Excel 2007, Microsoft

Office SharePoint Services 2007, and Microsoft SQL Server Reporting

Services

 However, many questions asked by business users cannot be

answered by this sort of analysis as they are not looking for the

results of what has happened, but instead they are looking for

predictions of what might happen

Predictive Analysis

Microsoft SQL Server Data Mining Add-Ins for Office 2007:

The Data Mining Add-Ins for Office 2007 empowers end users to perform advanced analysis directly in Microsoft Excel and Microsoft Visio

There are three individual components:

 Data Mining Client for Excel enables you to create and manage an entire Analysis Services data mining project from within Excel 2007

 Table Analysis Tools for Excel enables you to use the powerful Analysis Services data mining capabilities to analyze data stored in Excel spreadsheets

 Data Mining Templates for Visio enables you to render decision trees, regression trees, cluster diagrams, and dependency nets in Visio diagrams.

2 Reporting Service

 Microsoft SQL Server 2008 Reporting Services provides a complete based platform that is designed to support a wide variety of reporting needs including managed enterprise reporting, ad-hoc reporting, embedded

server-reporting, and web based reporting to enable organizations to deliver

relevant information where needed across the entire enterprise

 Reporting Services 2008 provides the tools and features necessary to

author a variety of richly formatted reports from a wide range of data

sources and provides a comprehensive set of familiar tools used to manage and secure an enterprise reporting solution

 SQL Server 2008 Integration Services meets the challenges of cleansing, transforming, and mapping multiple data sources with large volumes into a useful format

 New features improve its ability to scale up and improve

performance while speeding development and lowering the TCO

Integration Scenarios

to “close the loop,” (i.e., to

analyze, and take action on new data) increases as well These traditional ELT architectures (as opposed to value-added ETL processes that occur prior to loading) impose severe

restrictions on the ability of

systems to respond to emerging business needs

Application of SSIS Beyond Traditional ETL

SSIS, the Integration Platform

SSIS, the Integration Platform

SSIS for data transfer operations

 SQL Server 2008 Integration Services has an improved wizard that uses ADO.NET, has an improved user interface,

performs automatic

data type conversions,

and is more scalable

than previous versions.

MS SQL Server 2008

SSIS for data warehouse loading

 SQL Server 2008 includes support for Change Data Capture (CDC).

 SSIS can consume data from (and load data into) a variety of

sources including managed (ADO.NET), OLE DB, ODBC, flat file, Microsoft Office Excel®, and XML by using a specialized set of

components called adapters

Figure 3 shows an

example of such a flow

 Figure 5 shows the data flow that

is generated by this Wizard

MS SQL Server 2008

SSIS and Data Quality

 One of the key features of SSIS, as well as its ability to integrate data, is its ability

to integrate different technologies to manipulate the data This has allowed SSIS

to include innovative “fuzzy logic”–based data cleansing components

 SSIS deeply integrates with the data mining functionality in Analysis Services Data mining abstracts out the patterns in a dataset and encapsulates them in a mining model

 Support for complex data routing in SSIS helps you to not only identify

anomalous data, but also to automatically correct it and replace it with better

values This enables “closed loop” cleansing scenarios

 Figure 6 shows

an example of a closed loop

cleansing data flow.

a data source in the Report

Wizard.

SSIS, the Integration Platform

 SSIS goes beyond being an ETL tool not only in terms of enabling nontraditional scenarios, but also in being a true platform for data integration SSIS is part of the SQL Server Business Intelligence (BI) platform that enables the development of end-to-end BI

applications

Scripting

Integrated development platform

 SQL Server Integration Services, Analysis Services, and Reporting Services all use a common Microsoft Visual Studio® based

development environment called the SQL Server Business

Intelligence (BI) Development Studio BI Development Studio

provides an integrated development environment (IDE) for BI

application development
