基于Service Broker的异步分布式系统的设计与实现

A distributed asynchronous computing framework based on Service Broker

针对当前电子商务面临的海量数据处理和高吞吐量的需求,设计了一个异步计算的分布式系统。该系统使用SQL Service Broker作为分布节点间异步通信的载体,采用面向服务的数据库设计理念,使用NT Service作为逻辑处理单元,由Web ervice进行发布,完成了基于Internet分布式异步计算。在此基础上实现了简单的订单系统,证明了系统的可行性。

With the increasing needs for processing massive amount of information and high throughput in e-business systems,this paper presents a design of a distributed asynchronized computing framework. The framework takes SQL Service Broker as information carrier among distributed nodes,and NT Service as logical unit. Referring to Service Oriented Database Architecture,applications are encapsulated and published by Web Service. An simple order system based on this framework shows the design can be implemented well.
