A system and method are described for automating navigations in systems with measurement data that are structured as a multidimensional database (MDDB). The navigation includes an Automated Navigation Engine that uses external representations of a dimension selection function and a cube selection function to guide MDDB navigations. The method consists of the steps: (1) select the MDDB dimension that has the largest dimension selection score; (2) if this score is too small, terminate the method; (3) otherwise, select the cube with the largest cube selection score. These steps are performed repeatedly until (2) applies. Navigations can be performed for data mining, problem isolation, trending analysis, etc.
