2 AGENDA Let s demystify BI The business case for business intelligence To OLAP or not to OLAP BI Tools you may already have Data storage to drive decision support Information analysis Distributing Intelligent information How we can help

3 LET S DEMYSTIFYBI What is Business Intelligence(BI)? BI is an umbrella term to describe concepts and methods to improve business decision making by using fact-based support systems Technologies and practices which help business better understand commercial information Provides historical, current, and predictive views of business operations Aims to support better business decision-making by providing relevant, accurate and accessible information

4 LET S DEMYSTIFYBI OLAP stands for online analytical process: Uses a database which is structured in such a way to optimise analysis of business information Tool which utilises a multidimensional data model, allowing for complex analytical and ad-hoc queries with a rapid execution time OLTP stands for Online transactional process: Use a database which is structured for effective transactional processing. Systems that facilitate and manage transaction-oriented applications, typically for data entry and retrieval transaction processing, such as legacy ERP systems.

5 LET S DEMYSTIFYBI What is a Data Warehouse? Provides data storage which is structured and organised for the flow of data from operational systems to decision support environments. What is a Datamart? Typically a subsection of an data warehouse or organizational data store, usually oriented to a specific purpose or major data subject, that may be distributed to support business needs.

6 LET S DEMYSTIFYBI What is multidimensional analysis? Provides useful insight into your information by providing multiple perspectives within a hierarchical structure. Is a data analysis process that groups data into two basic categories: data dimensions and measurements. Dimensions are grouped information structured in levels. Measures are data values of statistical interest Collection of dimensions and measures is called cube US Canada Mexico [1997] [1998] [1999]

7 DATA STORAGE TO DRIVE DECISION SUPPORT Using Multidimensional analysis 4.Filtering 1.Multidimensional analysis Demonstration 3.Dragging and Dropping 2.Slicing and Dicing

8 THE BUSINESS CASE FOR BUSINESS INTELLIGENCE Increase Decision Making Ability Structure information in a more intuitive and meaningful way Provides a consistent view of your information. Empowerment Of Users by BI analysis tools rather than static reports Increase data reach Store historical information

9 IMPLEMENTING BI Storage OLTP sources but you limited Using a Data warehouse database as a central source for all business information Then a big technological, skills and cost leap.. Store information in a OLAP multidimensional tool Data Analysis Microsoft Excel 2007 provides excellent BI analysis features Distribution Microsoft Sharepoint Server 2007 and Excel services

10 TO OLAP OR NOT TO OLAP!!! Using a OLAP multidimensional tool such as Microsoft Analysis Services ( included in Microsoft SQL 2000) means BI becomes expensive: Disadvantages: Requires unique skills which are not widely available Develop a dimensional data architecture Advantages: Advance BI technologies such as data mining and predictive analysis available Delivers rapid analysis of large volumes of information

11 TO OLAP OR NOT TO OLAP!!! Use a data warehouse with BI analysis tools. Disadvantages: Aggregation of measures will happen on client and will be slower and there is a limit to volume of information to analysis. It s as fast as a crystal report and handles a couple of 100,000 s reasonably comfortably Advanced BI techniques not available Advantages: Microsoft SQL skills widely available A data warehouse is scalable up to a multidimensional tool

12 BI TOOLS YOU MAY ALREADY HAVE Tool BI functionality type Factors Microsoft SQL Sever 2000 Storage Used with Fourth Shift V7.11-V7.4 Microsoft SQL skillsare widely available Microsoft SQL Sever 2005 Storage Used with Fourth Shift V7.4+ Microsoft Analysis services 2000(DTS) Storage Specific set of skills Microsoft Analysis services 2005(SSIS) Storage Microsoft Excel 2003 Analysis Limited BI analysis functionality Microsoft Excel 2007 Analysis Sharepoint Services Distribution Comes with Windows Server 2003 Sharepoint Server 2007 Distribution

13 DATA STORAGE TO DRIVE DECISION SUPPORT Using a Fourth Shift database(oltp) directly Technical Fourth Shift business foundation views phase 1+2 Business foundation views phase 2 is important for historical data analysis Use data view templates for help building your own business SQL data view Use import and export wizards to get you going with DTS Use SQL OLE DB service provider to provide information to client Can use SQL non-clustered indexes to optimise performance with care Best practise Build a business SQL data view library using the business foundation views Relatively simple to utilise information from other data sources and systems Using inbuilt SQL data connection service providers it is almost seamless to use Microsoft office products with Microsoft SQL Server Considerations Fourth Shift is a OLTP system and locking and performance issues will prohibit scalability Limited ability to improve performance using optimisation techniques Complex queries are slow to execute It is adventurous to fully document your business data view library removing confusion and stops re-creation of views

14 DATA STORAGE TO DRIVE DECISION SUPPORT Using the Fourth Shift SQL database directly 1.Fourth Shift business foundation views Demonstration 3.Using SQL connection providers with Microsoft office products 2.Importing data into SQL from other sources

15 DATA STORAGE TO DRIVE DECISION SUPPORT Creating your own Data Warehouse database Technical Use SQL Data transformation services for the ETL process (use import\export wizard initially) Information can transferred at regular intervals throughout the day SQL record changes can be picked by using the version field on every Fourth Shift table Fourth Shift Update, delete and insert transactions can be identified and replicated in business information database Same process can be utilised with Fourth Shift history Best Practise Use your business data view library Define the structure of your business information database using some OLAP principals Use information from other sources Information can be updated at regular intervals for example every 5 minutes emulating real-time Can be used for all you business analysis required including multidimensional analysis, reporting and ad-hoc information requests Considerations A solution for locking, performance and scalability issues of using Fourth Shift directly Use all SQL database design techniques to optimise data retrieval such as indexing and links Fully documenting your business information database will stop confusion and recreation of database objects

16 DATA STORAGE TO DRIVE DECISION SUPPORT Using Microsoft SQL Analysis service 2000 Establish a database using dimension architecture which utilises your data warehouse BI Accelerator dramatically speeds up the process of creating a multidimensional cube in Microsoft Analysis services Griff & Jones have developed a product which interfaces between Fourth Shift( or data warehouse) and the Microsoft BI Accelerator tool.
