This paper proposes a multidimensional schema
management approach by focusing on the dimension
version update to support the multiple versions query
in OLAP application. The evolution support of the
multidimensional database (MDB) is based on the
schema versioning concept. We introduce the Direct
Access Versioning (DAV) technique to minimize cost of
schema version creation of the MDB schema
appearing in data warehouse (DW) systems. The
technique maintains the change of dimension data by
retaining only the changed class of dimensions in a
supporting dimension version (SDV) which will be
available for an immediate construction of any schema
version. Thus, the efficiency of schema version
construction is significantly improved since no
dynamic dimension instance conversion is required.
