Avalanche Laboratory OÜ (Avalanche) is an IT consulting company. As a young company, we are still building our resumé. However, we don’t want to hide the great achievements that our employees have accomplished. If we speak about BI Data Warehouse projects, then here we have built data warehouses for Estonian Energy and Omniva (Estonian Post). As a result of mentioned projects, Business is able to make better data driven decisions. Additional complexity and value was gained through constant need to unify different production and operational units data in one consolidated model. Such approach provides best use of data, when final users receive a single point of truth with validated data.
