Oak Enterprises Data Warehouse Certification
Why perform a Data Warehouse Certification?
What good is a data warehouse if the data is no good? The quality and transfer of data must be accurate and complete - or else you jeopardize user acceptance. Once the data warehouse data is perceived as unreliable, it is next-to-impossible to reverse this opinion. Users simply stop using the data warehouse. Your investment becomes virtually worthless.
To ensure against this, take the extra time and effort to certify the data warehouse upfront.
What is an Oak Enterprises' Data Warehouse Certification?
The Oak Enterprises' Data Warehouse Certification process verifies that the data warehouse is capturing the correct information and that the resulting output is accurate and complete. Done before the data warehouse is actually implemented, certification is a critical step involving analysis of both the data and the processes that extract the data from the various sources throughout the organization.
Oak Enterprises' Data Warehouse Certification also confirms that both the initial "baseline" data and all subsequent refreshes (imports) of the data are correct.
The end result is a data warehouse that is accurate, complete and stable. User acceptance is assured, as is your return on investment (ROI).
Oak Enterprises' Approach and Methodology
Oak Enterprises works collaboratively with your business and IT personnel to conduct the data warehouse certification. Depending on the internal resources available, Oak could complete the entire certification process or simply develop the certification process project plan for you to carry out. This process includes:
- Content Certification
Analyzing the content of the populated data warehouse for accuracy and comprehensiveness. At least two test cycles are conducted - one after the initial conversion of historical data and a second after a subsequent refresh.
- Process Validation
Verifying the reliability of the processes that extract, transform and load the data warehouse from its data sources.
- Data Quality Verification
Examining the quality of the data being moved into the data warehouse.
The end result is a quality data warehouse with high user acceptance - plus the elimination of costly rework after the data warehouse has moved into production.
