基于DXQ的分布式XML数据服务中心框架

Framework of distributed XML data service center based on DXQ

为了省却企业数据集成中复杂中间件的开发,提出了一个分布式XML数据服务中心的框架。讨论了在分布式XML/XQuery查询处理和XML数据集成中面临的问题,基于这些问题,阐述了目前最新的研究进展和相关技术。通过比较,采用了相对较为先进的DXQ语言和Galax引擎来处理分布式XML查询,并结合面向服务架构(SOA)方便了XML数据服务的增加和获取,同时采用动态负载均衡的技术来平衡整个框架的负载。

In order to dispense with the complex middleware in enterprise data integration,a framework of a multi-node XML data service center is presented.Firstly,the problems are described,which distributed XML query processing and XML data integration.Then,based on these problems,the latest research progress and solutions of distributed XQuery processing is reviewed.Through com-parison,DXQ language and Galax XQuery engine is adopted to do the distributed XML query processing.The framework also utilizes service oriented architecture to ease XML data service adding and requesting and dynamic load balancing techniques to balance the load between the server nodes.
