Management dashboards and control centres of a company are now the nucleus of corporate decision-making. Increasingly large data streams are having an ever greater influence on these systems – the more source systems, the greater the susceptibility to errors. However, the company’s KPIs are one of the decisive factors for processes, products and jobs, which is why they should under no circumstances be based on incorrect or missing input. Therefore, the correctness of the ETL processes and thus verified data streams within the business intelligence systems and data warehouses are of utmost importance. This is because the data is often extracted from a wealth of heterogeneous source systems and formats, transported and converted into comprehensible, well-prepared and, above all, correct reports and analyses. We can verify these processes with the help of our test methods within your compliance regulation and ensure that your business analyses are always of the highest quality.
