Enrico Franconi, Gabriel Kuper, Andrei Lopatenko, Luciano Serafini

摘要:

在本文中,我们给出了一个强大的对等数据库系统的逻辑和计算特性。我们首先定义了一个精确的模型理论语义的对等系统,它允许本地不一致处理。然后,我们将一般的计算性质的问题回答这样一个对等系统的查询。最后,我们设计紧密的复杂性界限和分布式程序的问题,回答查询在一些相关的特殊情况下。

英文摘要:

In this paper we give a robust logical and computational characterisation of peer-to-peer database systems. We first define a pre- cise model-theoretic semantics of a peer-to-peer system, which allows for local inconsistency handling. We then characterise the general computa- tional properties for the problem of answering queries to such a peer-to- peer system. Finally, we devise tight complexity bounds and distributed procedures for the problem of answering queries in few relevant special cases.
