Data Warehouse
Data Warehouse
What is a Data Warehouse, and why should you use one?
A data warehouse is where you store data from multiple data sources to be used for historical and
trend analysis reporting. It acts as a central repository for many subject areas and contains the
“single version of truth”. It is NOT to be used for OLTP applications.
What a Data Warehouse isn't:
A data warehouse is not a copy of a source database with the name prefixed with “DW”.
It is not a copy of multiple tables (i.e. customer) from various sources systems unioned together in a view.
It is not a dumping ground for tables from various sources with not much design put into it.

Data Maturity Model
Reasons to leverage the power of a Data Warehouse:
- Reduce stress on production system
- Optimized for read access, sequential disk scans
- Integrate many sources of data
- Keep historical records (no need to save hardcopy reports)
- Restructure/rename tables and fields, model data
- Protect against source system upgrades
- Use Master Data Management, including hierarchies
- No IT involvement needed for users to create reports
- Improve data quality and plugs holes in source systems
- Easy to create BI solutions on top of it (i.e. SSAS Cubes)
- Restructure/rename tables and fields, model data
