Datawarehouse Testing




Business Intelligence (BI) is becoming lifeline of business today with more and more leaders relying on accurate sourcing and representation of data to take business critical decisions. This requires data warehouses and business intelligence applications which can answer exactly the types of questions that users would like to pose against real-time data.

CresTech’s BI and Data warehouse testing solutions focus on testing complex business rules and transformation built using ETL logic. Using our suite of propriety utilities like DDF (Data Differential Framework) and FDF (File Differential framework), we test schema changes, data integrity and transformation logics across all phases of data acquisition, ETL, OLAP and reporting. We have worked with industry standard solutions like Microstartgy, Oracle BI, Informatica, Cognos amongst others

Our suite of BI and Data warehouse testing solutions include:

ETL, OLAP and Reports testing: Right from testing Extraction logic, transformation rules, data loading quality and integrity to validating all the OLAP cube dimensions across measures and measure groups to testing reports (drill throughdrill down) we test BI implementation end to end
