| Abstract: | Metadata management system is the core of construction and management and maintenance and use data warehouse system. The keys of metadata management lie in the construction a comprehensive and extended metadata model which describes all kinds of metadata. This paper presents a General Metadata Model(GMM) which can support management and maintenance of data warehouse effectively, such as management of the user view, personalized service, incremental refreshment, data lineage tracing, etc. |
