ReplyDeleteThe Extraction Structure is the Quantity of data fields to be transferred. The extraction structure contains the amount of fields that are offered by an extractor in the source system for the data loading process. And hence, one can say that you can filter or enhance the data ready for loading to the info cube.
E) An InfoCube consists of several InfoObjects and is structured according to the Star Schema. This means there is a (large) fact table that contains the key figures for the InfoCube, as well as several (smaller) dimension tables which surround it. The characteristics of the InfoCube are stored in these dimensions.
