We have implemented Soft Real-Time DBMS prototype called ZDBMS. Using this prototype we have investigated performance for commonly used policies EDF, LSF and for new transaction handling policy SPF oriented for using in cases when transactions have different static priorities. The results represent these policies performance for equal sets of experiments. 1(More)
This paper describes how materialized views could be used in distributed Real-Time Database Management System. We provide algorithm for dynamic materialized views building and cost evaluation. The main difference of provided method is that we take into account temporal properties of base relations and data manipulation operations. Experimental part provides(More)
