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).
