The Arizona Experience
Arizona Department of Transportation Information Management and Architecture
The illustration shows the organization of Information Management and Architecture within the Arizona DOT. The architecture is broken into two major sections, "Day-to-Day Operational Management," and "Information Management."
"Day-to-Day Operational Management" includes five Systems: Pavement; Bridge; Financial; Project; and Other. These systems interrelate with three Data Stores: Transportation; Finance; and Driver/Motor Vehicle. Operational Management also includes Online Transaction Processing (Business Units Are Owners of Data).
"Information Management" consists of the Arizona Information Data Warehouse, which encompasses four Data Marts: Highway Performance; Transportation Asset; Highway Usage; and Human Resources, and a module that includes Business Intelligence; Data Mining; End-User Query; and GIS Capabilities. Information Management also includes Online Analytical Processing (Office of Information Technology Is Custodian of Information).
