a message oriented middleware-based distributed query system

在三层结构中,中间层的实现是整个系统的核心.提出了一个基于消息中间件实现中间层的结构框架,能够以较少的花费实现一个分布式查询系统.中间层各个业务组件利用消息中间件通信,屏蔽了网络复杂性,实现异构平台的互操作,利用持久队列可以确保通信的可靠性,减轻了系统的开发工作和复杂度

a heterogeneous forms exchange platform for logistics enterprises

物流链企业之间存在着大量的电子表单交换需求,如订货单、发票等。这些表单主要以EXCEL表格、TXT文件、XML文件为载体。由于交互的企业之间使用的操作系统不一致、应用系统不一致、数据格式不一致,这些异构表单的交换已经成为物流企业数据交换的瓶颈。研究可扩展的异构表单交换平台架构、复杂表单的自动识别等技术,设计并实现一种面向物流企业的第三方异构表单交换平台。国家自然科学基金项目; 新疆大学SRT重点项目There are a large number of exchange requirements on electronic forms among enterprises in logistics chain,such as the orders, invoices,and so on. These forms mainly use EXCEL spreadsheet,TXT file and XML file as the carrier. Since the enterprises differ from each other in their operating systems and application systems used,which cause the incongruence in data formats,the exchange of heterogeneous forms has become the bottleneck of logistics enterprise data exchange. Therefore in this paper we study the architecture of scalable exchange platform for heterogeneous forms and the automatic identification technology for complex forms,and have designed and implemented a thirdparty logistics-oriented heterogeneous forms exchange platform
