This paper proposes a temporal version mapping concept and a SQL query rewriting technique to support the OLAP query analysis in multidimensional database (MDB) systems modeled on multiversion schema. Based on our proposed model, an integration solution of MDB schema change and multiversion OLAP query analysis performed over the changed database schema are taken into account. In addition, we present the system design and implementation of our prototype system to demonstrate our research idea.
