Data Warehouse - definition

“A collection of data designed to support management decision making.

Data warehouses contain a wide variety of data that present a coherent picture of business conditions at a single point in time.

The term data warehousing generally refers to the combination of many different databases across an entire enterprise.”

Spatially-enabled databases are becoming increasingly widespread and are no longer the preserve of large, enterprise, geo-spatial data stores

Demand for information sharing across organisations and partnerships

Adoption of Standards for Open Geospatial Consortium, Inc.® (OGC) data standards and interfaces

Advances in database usability and network capability

GIS becoming more mainstream IT
