Abstract: Data warehousing is emerging as one of the hottest areas of growth
in global business and the critical component and tool for business
intelligence. In the data warehouse environment, the level of summarization
plays an important role. Some Data Warehouse applications, directly account for
the uncertainty and vagueness often associated with time-series and
enterprise-wide decision making. In this paper, we enhance the concept of
summarization using fuzzy technology, keeping in view the time-series and
enterprise-wide data. This enhancement, which extends the aggregation process
used in data warehouse, provides insightful information intelligently and
allows greater facility for modeling human decision making.
Keywords: data warehouse, fuzzy sets, membership function, summarization
