Updating olap dimensions

Even when data is manipulated it remains easy to access and continues to constitute a compact database format. Multidimensional structure is quite popular for analytical databases that use online analytical processing (OLAP) applications.Analytical databases use these databases because of their ability to deliver answers to complex business queries swiftly.Follow these steps to enter a new drill-through table in SAS OLAP Cube Studio.OLAP tools enable users to analyze multidimensional data interactively from multiple perspectives.

Because usually there are many aggregations that can be calculated, often only a predetermined number are fully calculated; the remainder are solved on demand.Each measure can be thought of as having a set of labels, or meta-data associated with it.A dimension is what describes these labels; it provides information about the measure.Aggregations are built from the fact table by changing the granularity on specific dimensions and aggregating up data along these dimensions.The number of possible aggregations is determined by every possible combination of dimension granularities.MOLAP (multi-dimensional online analytical processing) is the classic form of OLAP and is sometimes referred to as just OLAP.
