The National Institute of Corrections specifically
identified Oakland County’s Criminal Justice Data
Warehouse as one of its most effective tools for
maintaining jail efficiencies

How did we help Oakland County manage these problems?
Built a complete data warehouse from the ground up, including
everything from concept, to construction and testing, to
implementation
Built in three phases based on subject area
Constructed a wide-range of reports based on business-user
requirements
– Many reports sent out automatically via email
Trained Oakland County’s staff to understand and query the
data themselves on a limited basis (power users)

Key Concept—Data Quality
Direct correlation between data quality and report quality
Integration of data between subject areas typically relies on one
field
Bad data in that field = no data integration
