What is a Data Warehouse?

The Ohio Human Services Data Warehouse (OHSDW) involves the consolidation of multiple data sources into one centralized database to report a regional and statewide picture of homelessness. Ohio's data warehouse will begin with a collaboration of homeless Continuums of Care and their respective Homeless Management Information Systems (HMIS). Additionally, this collaborative expects to expand to include cross-system data sources necessary to develop a holistic picture of homelessness in Ohio while furnishing reliable, comprehensive data.
