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.”

What’s required ?

“Collection of data” Oracle, PostGIS, SQLServer

“Wide variety of data” OGC Simple features specification Oracle – SDO_Geometry

“Systems to extract data ….. flexible access to the data” Intranet/Internet browser based access

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

Drivers for spatial data warehousing?

GeognoSIS

• Is a Windows service: ‘a Windows service is a long-running executable that performs specific functions and which is designed not to require user intervention’ (Wikipedia)

• Responds to requests from application code

• Does not necessarily need to render a map

• Can distribute mapping data using Web Services
