1. Executive Information Systems and The Data Warehouse

2. EIS-The Promise  EIS is one of the most potent forms of computing  Through EIS, the executive analyst can pinpoint problems and detect trends that are of vital importance to management.  EIS processing is designed to help the executive make decisions.  Some of the typical uses of EIS are :  Trend analysis and detection  Key ratio indicator measurement and tracking  Drill-down analysis  Problem monitoring  Competitive analysis  Key performance Indicator monitoring

3. A Simple Example

4. Drill-Down Anaysis Example 1 Example 2

5. Supporting the Drill-Down Process  How to supporting the drill down process ?

6. The Data Warehouse as a Basis for EIS  With a data warehouse, the EIS analyst does not have to worry about the :  Searching for the definitive source of data  Creating special extract programs from existing systems  Dealing with unintegrated data  Compiling and linking detailded and summary data and the linkage between the two  Finding an appropriate time basis of data  Management constantly changing its mind about what needs to be looked at next

7. Where to turn  The EIS function uses the following  The data warehouse for a readily available supply of summary data  The structure of the data warehouse to support the drill-down process  Data warehouse meta data for the DSS analyst to plan how the EIS system is built  The historical content of the data warehouse to support the trend analysis that management wishes to see  The integrated data found throughout the data warehouse to look at data across the corporation

8. Event Mapping  What is event mapping ?  Why using event mapping ?  Example

9. Detailed data and EIS  Is so wrong with keeping all the detail in the world around when building a DSS/EIS environment ?  Keep only summary data in the EIS
