Check out the Data Warehouse Audit service. Our Business Intelligence Specialists will present our standards for conducting data warehouse audits. During a standard audit, we can conduct a quick and accurate analysis of the current state of the Data Warehouse or prepare a list of steps to be taken before migrating or implementing a new Data Warehouse on the Azure platform. The detailed scope of the audit is determined individually, but usually covers key, permanent areas:

  • analysis and evaluation of the architecture of the Data Warehouse layers,
  • business needs coverage analysis,
  • analysis of the correctness and optimality of the Data Warehouse model,
  • verification of the processes supplying the Data Warehouse,
  • assessment of the adequacy and optimization of the selected ETL and BI tools available on the Azure platform.

We will share with you our best practices, and proven implementation methodologies, based on many years of experience in the Business Intelligence department.
