Fuzzy MDX queries for taking into account the ambiguity in querying the baccalaureate data warehouse

The decision maker tends to use natural language terms when interrogating a data warehouse, hence the need to integrate these terms into the data warehouse interrogation systems. In this article, we present a panorama of the work that has dealt with the treatment of ambiguity in decision-making queries and propose a solution that uses fuzzy logic and allows the interrogation of the data warehouse with terms derived from the language using fuzzy MDX queries.
