Multidimensional information is pervasive in many computer applications including time series, spatial information, data warehousing, and visual data. While semistructured data or XML is becoming more and more popular for information integration and exchange, not much research work has been done in the design and implementation of semistructured database system to manage multidimensional information efficiently. In this paper, dimension operators have been defined based on a multidimensional logic which we call ML(ω). It can be used in applications such as multidimensional spreadsheets and multidimensional databases usually found in decision suport systems and data warehouses. Finally, a multidimensional XML database system has been prototyped and described in detail. Technologies such as XSL are used to transform or visualise data from different dimensions.
