In one embodiment, the present invention includes, a method comprising receiving a first query in an online analytic processor (OLAP) executing on one or more computers, the OLAP generating and comprising a model specifying a graph defining a plurality of nodes and a plurality of tiers, each node corresponding to a different operation on data. A second query is generated by the OLAP.
