| Summary: | Data Warehouse has become a very important tool for data
analysis but the conversion from Operational Database to Data Warehouse
is very complex. This paper presents a new method to design a
data warehouse multidimensional model based on supply driven framework.
We propose a semi-automatic tool using lexical ontology as the
knowledge domain. The tool is able to identify fact and dimensional
tables using the knowledge domain. Once fact table is identified, the
following step is to generate Data Warehouse multidimensional model
with minimal user interaction. The feasibility of the proposed method is
demonstrated by a prototype using WordNet as knowledge domain. |
