| Abstract: |
| Objective To solve the issue of the construction of multidimensional data model in the implementation of equipment support data warehouse. Methods This paper summarized multidimensional data modeling methods in recent years, optimized the ontology-based multidimensional data modeling method and put forward a new method of establishing multidimensional data model-" ontology-AHP" construction method. Results This method conveniently extracted the dimension and indexes for the data model from the large equipment support system and simplified the construction process of multidimensional data modeling. Conclusion It provided strong support for the implementation of equipment support data warehouse. |
