摘要：A large variety of Web-based applications demand access and integration of up-to-date information from multiple distributed and heterogeneous information systems. Data-Sharing Environments(DSE) contribute to the achievement of information superiority which will enable decision dominance. The goal of DSE is to help data interaction between distributed and heterogeneous information sources. One challenge in Data Sharing is how to select the right data at the right time and right cost. We call this problem as quality of service(QoS) guarantee in DSE. In this paper, we model the problem and present an efficient mechanism to deal with QoS guarantee in DSE
