How To Use Office 2000 Features In Data Warehousing Michael L. Flakus Senior Consultant BEST Consulting

Session Prerequisites  This session assumes that you understand the fundamentals of:  Basic knowledge of Office 2000  Basic knowledge of Microsoft ® SQL Server ™ 7.0  This is a level 200 session

What You Will Learn Today  Using Excel 2000 PivotTable and PivotChart to access Multi-Dimensional data  Using PivotTable and Chart Office Web Components (OWC) to access Multi- Dimensional data  Overview of Microsoft SQL Server OLAP services and functionality

Definition Of Terms  OLTP – On-Line Transaction Processing  OLAP – On-Line Analytical Processing  OWC – Office Web Components  OLAP Cube  OLAP.cub file  MDX – Multi-Dimensional Extensions

Data Warehouse Framework Source: Microsoft SQL Server 7.0 Data Warehousing Framework

Software And Components  Office 2000  Excel PivotTable and PivotChart  Office Web Components (OWC) PivotTable and Chart  Excel Microsoft Query  Used to create or open connection to data source  An optional Microsoft Office component  Internet Explorer (IE) 4.01 or greater (OWC do not work with Netscape Navigator)

Software Installation Tip  Include Microsoft Query in standard Office 2000 installation for users who will be creating or opening database connections

OLAP Data Source Options  OLAP Service Provider  Microsoft OLAP Provider  Third-party OLAP Provider (conform to OLE-DB for OLAP standard and be Office compatible) OLE DB for OLAP Web Site:  Offline Cube files (.cub)

About Offline Cube Files  Offline cubes files (.cub) from OLAP data  Can be created using Excel  Include as subset or all data  Allow users to continue working with data when disconnected from network  Can be updated when reconnected  Generally, provide slower performance  Do not include calculated measures  May not be supported by third-party OLAP providers

Creating A Data Source  To connect to OLAP data, you create a data source using Microsoft Query  Microsoft Query is invoked either;  While using the PivotTable and PivotChart wizard  Or, directly from the Excel 2000 menu

Today’s Demo Scenarios  Northwind sales representatives need to analyze company sales data  The Northwind IT department needs to broadly, easily, and securely provide access to the OLAP database  Overview of the process used to create an OLAP database

Demo 1  Scenario – Northwind sales representatives need to analyze company sales data  Solution – Provide interactive tools that allow users to view and explore OLAP data

PivotTable Options – OLAP  Note “Save data with table layout” is not available  Enabling “Refresh on open” is suggested  Disable “Save password”

PivotTable Options – Non-OLAP  For best performance, leave these two Excel PivotTable Options to default values as follows:  “Save table with data layout” enabled  “Refresh on open” disabled  Consider disabling “Save password”

Windows NT ® Integrated Security  OLAP uses only Windows NT integrated security  Offline.cub files do not have this protection

Best Practices  OLAP Data sources provide best performance for large or frequently refreshed data sets  Selecting and linking data in an OLAP data Source is not required  Offline Cube files do not use Windows NT Security

Pop Quiz  What is Microsoft Query used for?  Why do OLAP data sources generally provide better performance with large or frequently accessed data sets? A: Connecting to an OLAP data cube A: They use a client / server architecture and return only the selected data

OWC PivotTable And Chart

Office Web Components  Office Web Components (OWC) – OWC are included in Office 2000 and behave similarly to other office applications, but operate in an internet environment These components include:  The Spreadsheet Component  The Data Source Component  The Chart Component  The PivotTable Component

Demo 2  Scenario – Interest in Northwind’s OLAP data has grown within the company; The IT department needs to broadly, easily, and securely provide access to the OLAP database  Solution – Use the Web to distribute PivotTable and Chart views of OLAP data

OWC And Office 2000  No technical dependency  Office 2000 does not need to be installed before deploying OWC  Can coexist with Office 95 and 97  OWC components are licensed with Office 2000  Compatible with Office  Can be deployed before Office 2000

OWC Component Install  Create an Office 2000 Install Image using setup.exe /a or the ORK that installs the OWC  Set Codebase Attribute to MSOWC.CAB to call the Web installer control  For more information see Chapter 12 of Programming Microsoft Office 2000 Web Components by Dave Stearns (MS Press, 1999)

Pop Quiz  How are Office Web Components Licensed?  Which components are used to access OLAP data? A: With Office 2000 A: PivotTable and Chart  Do the component require Office 2000 to be installed on the workstation? A: No, they can be installed independently

Demo 3  Scenario – Produce OLAP multi-dimensional database from OLTP data source  Solution – Provide tools to enable the creation of multi-dimensional databases

OLAP Database Backup And Recovery  The entire database can be backed up with standard file server backup routines  OLAP Add-in Package allows the backing up and restoring of individual OLAP database

Best Practices  Clearly communicate to users the structure, origin, and content of the source data  Learn techniques to improve build and viewing performance  OLAP Services: Performance Implications of the Architecture

Pop Quiz  What does OLAP represent? A: Online Analytical Processing  What happens in the back room of the process? A: Data is extracted, transformed, and loaded into a multi-dimensional schema  What happens in the front room of the process? A: Data is presented in a secure manner to the end-user for analysis

Why OLAP Services And Office 2000? Intelligent aggregations  Significantly smaller databases for same performance  Faster initial and incremental load times Flexible storage architecture  Supports MOLAP, ROLAP, and HOLAP equally well  Application requirements determine storage Ease-of- mgmt  Lower TCO  Broader accessibility of data warehousing PivotTableService  Client-side cache - improves performance  Client/server architecture for Excel PivotTables
