Question
Q1. Consider the following fact table about sales: Product Time Drinks Bread $20000 $25000 $35000 $10000 $10000 $10000 July August Sept $15000 $15000 Oct $20000 Nov $20000 Suppose the Time dimension hierarchy has three levels: month → quarter → all, and the Product dimension has two levels: item → all. July and August belong to the summer quarter, and Sept and Oct and Nov belong to the fall quarter. (a) List all derived cells that involve quarters, together with their total dollar values. (b) Give an example of drill down involving two cells (list both the "from" cell and the "to" cell). (c) Give an example of roll up involving two cells (list both the "from" cell and the "to" cell). Q2. Use the fact table in Q1 to illustrate what is meant by “the sum() measure is distributive", what is meant by "the avg() measure is not distributive", what is meant by "avg() is algebraic", and what is meant by “the median() measure is not algebraic".
