14、atform and turn business insight into effective actions.2007 Microsoft Office System IntegrationThe SQL Server 2008 BI platform reaches information workers through the following 2007Office System components:Microsoft Office Excel. Microsoft Office Excel 2007 is a powerful spreadsheet application tha

15、t you can use as an interface for OLAP analysis, data mining, and report rendering. Through deep integration between SQL Server 2008 and Excel 2007, you can: Enhance the end users ability to access and analyze data from SQL Server2008 Analysis Services. With Excel2007, end users can browse data that

16、 is stored in multidimensional OLAP cubes in Analysis Services. Excel2007 enables users to easily build Microsoft PivotTable dynamic views to “slice and dice” data any way they wish through the tools that are already installed on most desktop computers. Gain more value from your Excel implementation

17、 by using the tight integration between Excel and Analysis Services that enables end users to easily use the Analysis Services features, such as translations, Key Performance Indicators (KPIs), calculated members, named sets, and the server actions in Excel that turn Excel into an analytical client.

18、 Make predictive analysis available to everyone and enable non-technical users to harness the highly sophisticated data mining algorithms of SQL Server2005 Analysis Services within the familiar environment of Office. Designed with the end user in mind, Data Mining Add-Ins for Office2007 empowers end

PerformancePoint Server is an integrated performance

26、 management application that employees can use to monitor, analyze, and plan business activities based on the analytical data provided by SQL Server2008.This white paper shows how SQL Server2008 and its integration with the 2007Office System can help you unify business intelligence data storage and

27、access, build and manage sophisticated BI solutions, and extend the reach of those solutions to all of your employees.Unifying Data Storage and AccessMost organizations have multiple business systems, each with its own dedicated data store. Although you can often generate reports from individual app

28、lications and perform analysis on the data they contain, you can only achieve complete and consistent insight into the business by consolidating disparate data throughout the enterprise to create a central source of business data for reporting and analysis.Consolidating Corporate Data for Analysis a

29、nd ReportingSQL Server 2008 supports two common approaches to unifying business data for analysis and reporting: Data warehouse. A data warehouse is a dedicated data store for enterprise-wide data, which is populated and synchronized with business data from disparate data sources throughout the ente

30、rprise. The key advantage of this approach is that you can design the data warehouse for optimal analytical and reporting performance with no impact on the performance of the line-of-business applications from which the data originates. Another advantage is that you can clean and consolidate data th

31、at comes from multiple sources into a single consistent version of the truth.Data source abstraction. SQL Server2008 Analysis Services enables the creation of data source views to provide an abstraction layer over one or more data sources. You can then use the data source view as a single source for

32、 Analysis Services, Integration Services, and Reporting Services. With a data source view, the data is retrieved from the underlying source systems when analysis occurs or a report is generated. This enables real-time analysis of the data in your business applications. Additionally, the data source

33、view through its added layer of abstraction can be used to create friendly names to replace long or cryptic table names.These approaches are shown in the following illustration. With SQL Server2008, you can use either one or a combination of the two.Work with All of Your Data the Way You WanttoRegar

34、dless of which approach you take to unify your business data, SQL Server2008 builds on its strong legacy of support for both relational and non-relational data by providing data types that enable developers and administrators to efficiently store and manage unstructured data such as documents and im

35、ages, so you can store, manage, and analyze data in the format that best suits your business.SQL Server 2008 includes enhanced support for XML data storage as well as a FILESTREAM data type that enables large binary data to be stored in the file system yet remain an integral part of the database wit

36、h transactional consistency. Additionally, restrictions on the size of user-defined data types have been removed, which makes it possible to exceed the 8-KB limit imposed in earlier releases of SQLServer. Support for spatial and location data types makes it possible to store and analyze geographical

37、 data that conforms to industry standards.Integrate All Enterprise Data SourcesSQL Server 2008 data source views enable integration of data and access to data that originates from heterogeneous enterprise-wide data stores, such as SQLServer, Oracle, DB2, and Teradata. These views also provide an OLA

38、P store of enterprise scale; the breadth of support for diverse data sources in SQLServer Integration Services means that you can extract data from all kinds of existing business applications. Therefore, unifying the data in all of your enterprise data sources is easy to accomplish, regardless of wh

39、ether you want to build an abstraction layer through a data source view or use an ETL process to synchronize a dedicated data warehouse for analysis and reporting.Additionally, through support for Web services and the Microsoft .NET Framework, SQL Server2008 supports interoperability with multiple p

40、latforms, applications, and programming languages, so you can maximize your investment in new and existing systems by integrating and connecting your disparate data sources. Support for existing and emerging open standards, such as HTTP, XML, SOAP, XQuery, and XSD, further facilitate communication a

41、cross your extended enterprise systems.Data Warehouse PerformanceSQL Server 2008 provides a comprehensive and scalable data warehouse platform that enables your organization to integrate data into the data warehouse faster so you can scale and manage growing volumes of data and users.Optimize ETL Pr

42、ocessesData warehouses are usually populated and updated with data from source systems through an ETL process. After the initial load of data into the data warehouse, periodic refreshes of new and changed data from the source systems are performed to ensure that the data warehouse is up-to-date.SQL

43、Server Integration Services provides a comprehensive platform that you can use to extract data from diverse source systems, make any required transformations to the data or its structure and format, and then load the transformed data into the data warehouse. Performing lookups to match records from

44、source systems to existing records in the data warehouse is a common operation in ETL processes, and in SQL Server2008 the performance of lookups has been significantly improved so that these operations scale to extremely large tables.To help track data changes and ensure data warehouse consistency,

45、 SQL Server2008 introduces change data capture functionality to log updates in change tables, which makes it easy to identify rows that have been modified and to determine the details of the modification and its cause.Manage Hardware Resources EfficientlyThrough support for data compression, SQL Ser

46、ver2008 enables you to store your data more effectively and reduce storage costs. In addition, the compression significantly improves performance for large input/output bound workloads. SQL Server2008 also provides native support out-of-the-box for backup compression. Additionally, the VARDECIMAL da

47、ta type and new sparse columns in SQL Server2008 help you get the most efficiency from your disk storage resources by reducing the amount of space that is required for the large tables that contain the predominantly numeric or NULL values that are often found in data warehouses.In addition to effici

48、encies in data storage, SQL Server2008 supports dynamic allocation of Address Windowing Extensions (AWE) mapped memory that supports up to 64gigabytes of memory with Windows Server2003, Datacenter Edition, and 2terabytes with the 64-bit edition, to support large data warehouse environments.SQL Server2008 also introduces Resource Governor, which enables administrators to define resource limits and priorities for different workloads, so that concurrent workloads can provide consistent performance
