Business Space Design for the Multi-dimensional on Line Data Analysis System

MOLDA (Multi dimensional On Line Data Analysis) is an OLAP system model, designed and developed by the author for the development of several business analysis projects. This paper introduces the design methodology of the "business space", which is the key technique for the development of the OLAP system based on MOLDA model. "Index dimension", "classification dimension", "time dimension" as well as "multi dimension data cube" and "concept layering" design are discussed in the paper.
