摘要: Peer-to-peer (P2P) computing offers new opportunities for building highly distributed data systems. Unlike client-server computing, P2P can operate without central coordination and offer important advantages such as a very dynamic environment where peers join leave the network at any time; direct fast communication between peers, scale up to large number of peers. However, most deployed systems have severe limitations: file-level sharing, read-only access, simple search poor scaling. In this paper, we discuss issues providing high-level management services (schema, queries, replication, availability, etc.) in system. This implies revisiting database technology major ways. We illustrate how address some these APPA system under development Atlas group.
