Using persistent objects to encapsulate multi-dimension data entities in a warehousing environment

A framework is explored for using persistent objects to encapsulate multidimensional entities in a data warehousing environment so that programmability can be promoted. An extension of ODL and OQL are used to support object oriented OLAP and meta business knowledge expression. This framework is applied to WEIR, a prototype project of data warehousing and knowledge discovery in data warehousing in our laboratory.
