1. June 14, 2006 1 Show Me the (DMH) Data How the Missouri Department of Mental Health is moving toward true Data Warehousing

2. June 14, 20062 Step 1 – Baseline 1994 situation Most DMH data on mainframe Used DB2 for “new” system. Older systems IMS or flat file processing systems Reporting only by IT staff using AS-IST Lots of “greenbar” Each report costs MF cycles

3. June 14, 20063 Step 2 – DMH Data Repository Began in 1994 with failed attempt to move new production Client Tracking System from MF/DB2 to AIX/Oracle. Gave report writers access to copy of production Over next 4 years added copies of transactional data from most core systems; later SAM II Added common identifiers to link between systems Now have 900 GB in 2629 tables, 900+ users Very successful compared to reporting against Tx systems on different platforms and databases

6. June 14, 20066 Challenges Building DW as part of development project Changes in database Lack of realistic data Lack of informed customer input Prioritization Need “some of everything” to start Prioritizing dimensional marts Inexperience with DW technologies Time and money (what’s new?)

7. June 14, 2006 7 Show Me the (Children’s) Data How the State of Missouri is moving toward an interagency Children’s Services Data Warehouse.
