Flexible data integration on the Internet: current trends and issues

Tamer Özsu

The emergence of the Internet as a fundamental communication medium brings new opportunities and challenges to data management. Internet-based applications require re-examination of basic assumptions about the way we manage distributed data. In this talk, we focus on how data integration is affected by these requirements. The applications that are built on the Internet do not lend themselves to static and restrictive integration architectures that have so far been developed. There is a need for more flexibility in the way component systems (data sources, applications, etc) can join and leave federated systems. There is a need for more sophisticated algorithms for data management that can take into account this flexibility and its consequences. These consequences require query processing techniques that can tolerate inconsistencies in data sources as well as fault-tolerant querying when components may disappear from the federation. The talk covers the issues and discusses some of the alternatives that can be followed. Clique no link abaixo para buscar o texto completo deste trabalho na Web: Buscar na Web
