Based on the previously proposed 2PE scheme, this paper proposes a new scheme called a 2-Phase Multiple Query Evaluation (2PME). The proposed scheme extends the 2PE scheme in a way that enables multiple multiway join continuous queries to be more efficiently processed. It constructs a global execution plan that clusters a common sub-query walk (SQW) shared by more than two queries. Each cluster is executed only one time instead of being executed repeatedly for every related query.
