Coherent Solutions delivers with best QA practices
The whole point of business intelligence is to use data to drive better decisions and outcomes. Thus, users and SMEs need to trust that the data is accurate and up-to-date. At Coherent Solutions we go to great lengths to assure that kind of quality in every data warehouse we build.
When talking about quality assurance in BI, creating test plans and cases comes immediately to mind – particularly for vulnerable bottlenecks like the ETL process. Every QA and developer knows these plans and cases must be created to validate and ensure accuracy of the ETL process at every stage of the project lifecycle. But we want to go deeper here to cover the logical concepts that are the cornerstones for delivering high quality data in a warehouse.
After successfully verifying, cleaning, integrating and aggregating the data it is ready to load into the data warehouse. At this stage we compare expectations with results through source-to-target testing. By applying our best QA practices at every stage, Coherent Solutions is able to assure the best results and highest level of trust to any BI system.
