The task was to extract data from the Access tables of an operational management control software (budget, standard costs, performance variances, actual costs) to transfer it to an SQL Cube hosted on an Azure server (applying a set of management rules to qualify the basic information) and produce PowerBI-type reports securely accessible by clients. Johan carried out this mission perfectly.
