In contrast to a normal disk storage, Ecrion BI tools use an In-Memory Database to provide the most efficient and powerful way to build and utilize your dashboards. By utilizing an In-Memory Database, the BI Architect can query, perform calculations, and other manipulations at higher speeds. When opening your dashboard, you will need to select the In-Memory Database configured in your setup of the BI Server.
When setting up or opening a Dashboard, you can always reference the In-Memory Database you are connected to by selecting Data Source button in the Home Tab in the Ribbon.
