MQM: a Multi-dimensional QoS Model for Navigating Web Services
With the rapidly development of Web,there are more and more Web services available for users to choose from.So,it is necessary to provide a query mechanism for users to search by QoS(Quality of service).However,the existing QoS management models couldn′t support query requirements,such as dynamic query,well.What's more,the query performance is also need to be improved.Therefore,we proposed a new Web service management model ——MQM(Multi-dimensional QoS Model),and introduced the approaches and algorithms of modeling it.MQM manages QoS data by multi-dimensional data model,which supports query and OLAP operations.Experiments show that MQM ensures users retrieve the services they need by QoS more accurately and faster,and it is a good solution to the problems of traditional models,such as cannot determine the intuitive query ranges,cannot adjust the query range dynamically,query performance is poor.
