When using two different data sources such as Google analytics and Adobe analytics from separate datalakes, would the user need to create 2 separate entities in the business model (one for Google and one for Adobe)?

No. With Timbr a user can map multiple tables from multiple data sources to the same concept. Therefore, users can leave their data wherever it is and just use Timbr’s data mapping tool to conveniently map data from the various data sources to the ontology model.
