Abstract
To support efficient graph OLAP operations on information networks, we propose two significant intermediate infrastructures: InfoNetWarehouse and InfoNetCube. InfoNetWarehouse is designed with novelty to be the warehouse model for information networks, which provides topic-oriented, integrated, and multi-dimensional organizational solutions for Information networks. InfoNetCube is our proposed datacube implemention that serves the OLAP of information networks. We further integrate the two infrastructures with InfoNetOLAP module into a prototype called InfoNetOLAPer, which has the following noteworthy features: (1) The basic InfoNetWarehouse schema is well implemented based on SQL Server 2000, (2) InfoNetCube improves the efficiency of InfoNetOLAP by the pre-computation of InfoNetLattice, and (3) InfoNetOLAPer supports efficient I-OLAP and T-OLAP operations.
