摘要

软件服务被认为是软件工程的下一大步。不可避免地,服务供应商和服务客户端程序都需要维护。我们提出了一个服务架构,它的动机是将软件作为一种被使用的东西,而不是被拥有的东西。该体系结构用于展示如何实现软件的演化。它使用市场来逐步推动过程。我们总结了一种新的容错私有信息检索方案,以保护用户的隐私并确保服务提供,即使存在有意/无意的服务提供者错误(例如恶意故障)。在实际的分布式数据库上的实现只会带来适度的性能开销。

Software services and software maintenance
Software services are being promoted as the next big step forward in software engineering. Inevitably, both service vendor and service client programs will require maintenance. We present a service architecture that has been motivated by a long term vision for software as something which is used, not owned. This architecture is used to show how evolution of software can be achieved. It uses the marketplace to drive the process incrementally. We summarise a new fault-tolerant private information retrieval scheme for protecting users' privacy and ensuring service provision even in the presence of intentional/unintentional service provider faults (e.g. malicious failures). An implementation on a realistic distributed database suggests only a modest performance overhead.
