9 Data Warehousing – Definition 1 Accepted definition: ‘Subject Oriented, Integrated, Non-volatile, and Time Variant Collection of Data in Support of Management’s Decisions’. Bill Inmon ‘Building a Data Warehouse’, 2nd edition, wiley 1996.

10 Data Warehousing – Definition 2 My definition: ‘A Data Warehouse is the enterprise single point of access to its data’

11 Data Mart – Definition A Data Mart is a project that uses Data Warehousing techniques, but covers only a selected part of the enterprise data  Examples:  Accounting Data Mart  Sales Data Mart

15 Dimensional Modelling A design method that is  Not entity-relationship modelling  Not normalised  Easily understood by users  More efficient for BI

16 Dimensional Modelling Example Consultants submit timesheets, showing the number of hours, the rate and their expenses per project per day. Managers (AD) are responsible for projects and consultants.

20 OLAP On-Line Analytical Processing  A data presentation method that allows the users to interactively change the criteria, the level and the contents  Usually based on a multi-dimensional model  Allows for drill-down, drill-up and drill-across

22 OLAP Methods  ROLAP  MOLAP  HOLAP  Relational OLAP (Business objects)  Multi-dimensional OLAP (Hyperion)  Hybrid OLAP (Cognos)

23 OLAP DEMO

24 Data Mining - Definition A method for automatically deducing knowledge from data:  Patterns, clusters, rules, decision trees etc’

27 The BI Assimilation Lifecycle Time ComplexityComplexity Bulk Reports Exceptio n Reports OLAP Alerts n months

28 Balanced Scorecard A method of organisational performance measurement. Performance of an organisation from four perspectives:  Customer perspective (how do customers see us?)  Internal capabilities perspective (what must we excel at?)  Innovation and learning perspective (can we continue to improve and create value?)  Financial perspective (how do our owners/shareholders see us?)

29 Information Quality Information is Data in context. Information Quality is Data Quality in context with meaning. The ability to trust the information  Data Quality  Reliable and repeatable testing  Metadata

30 Main Challenges in Business Intelligence Business intelligence projects are  User-oriented  Large  “Complex simplicity”  Continuously evolving  Require deep technical and business knowledge  Stretch all limits:  Time, storage capacity, CPU, machine communications, human communication, human perception, and teamwork.  Data Quality

31 What’s Happening in the BI world?  BI is becoming a norm  Mature, off-the-shelf tools  Combine structured and non-structured data  A small number of main players  New uses (Data Webhouse)  Real-time  Hosted BI  Open Source BI
