E. read only semantic. With planning new facts will be created or existing facts are manipulated. Therefore, the novel operators for planning must support this. From the list of basic planning functions shown in Section 3 not all require a separate operator. Similar to the original model, where typical OLAP operators like roll-up and The Planning OLAP Model - A Multidimensional Model 19 drill down are expressed in terms of the basic aggregation formation operator, we only need a few basic operators to keep the extended algebra simple and minimal.

The set of facts is the same, too, because the disaggregation operator does not introduce new facts. It only maps the facts for the target dimension to new values. The set of dimensions is again taken from the original M O, but the target dimension Dimt changes in the sense that intuitively the new dimension values are calculated based on the new sum and the fractions of the given reference dimension Dimr .
