For a uniform distribution, the reference aggregate function should be g = COU N T and for a constant distribution g −1 (er , enew , eold ) = enew . The following example illustrates how disaggregation works: we distribute a new article quantity of 384 to all sales facts in Germany for the year 2010. The input M O contains all 5 dimensions Article, Location, SellDate, Price and Quantity and is not restricted. The parameters for the disaggregation are: α−1 Article , Germany, 2010, P rice, Quantity , g −1 , g, enew = 384, t = 5, r = 5] (M O) = M O The distribution function g −1 is the standard function explained in the previous section and the reference aggregate function g is SU M .

Mappable markers (D2) are mapped to real data (either manually or in an automated fashion, depending on source’s metadata), now becoming mapped markers (D3: mapped marker); Step 3. Each grain-goal related to a chosen goal (D1) having all of its markers mapped (D3) will become satisfied (D5: satisﬁed grain-goal); Step 4. Once all satisﬁed grain-goals (D5) are found, the corresponding rationale AND/OR decomposition-trees are read to deliver satisfied goals (D6: satisﬁed goal) from the set of chosen goals (D1).
