Multi-dimension Multimedia Retrieval Model Implementation Based on XML Database

Derived from the thought of data warehouse, data cube and XML, this paper presents a new database structure model which organizes the multimedia data in a multi-dimensional data cube based on XML Database. In this data cube of XML, clustered data are stored in instance table. A leading data corresponding are stored in dimension table. The relational model is helpful to construct data model, but it lacks flexibility, now the new data model can complement the defect of relational model. When querying, a leading data is gained from dimension table of XML, then receiving the multimedia data through XQuery.
