DBIS-Toolkit: Adaptable Middleware For Large Scale Data Delivery

摘要

The proliferation of the Internet and intranets, advances in wireless and satellite networks, and the availability of asymmetric, high-bandwidth links to the home, have fueled the development of a wide range of new "dissemination-based" applications. These applications involve the timely distribution of data to a large set of consumers, and include stock and sports tickers, traffic information systems, electronic personalized newspapers, and entertainment delivery. Dissemination-oriented applications have special characteristics that render traditional client-server data management approaches ineffective. These include: tremendous scale, significant overlap in user data needs, and asymmetric data flow from sources to consumers.
