【摘要】 随着信息技术的发展,信息化对于企业生产效率的提高,正发挥着越来越大的作用。物流企业在信息化浪潮面前,也纷纷进行信息管理系统构建以增强自身在日益激烈的行业竞争中的竞争力。但是,现实情况是,对于我国众多的新兴中小物流企业,一方面面临着生存压力,一方面受市场拓展的牵制,对于物流信息管理系统构建难以保证足够的人力物力。然而,这些企业同样迫切需要物流信息管理系统来提高企业运行管理效率,降低成本,增强企业竞争力。鉴于此,本文基于Microsoft成熟的.NET平台,利用ASP.NET、WCF(Windows Communication Foundation)、Entity Framework等开发技术,设计实现了轻量化SOA架构(Service-Oriented Architecture,面向服务架构)的物流信息管理系统。利用SOA松散耦合、灵活性好、扩展性强的特点,为中小物流企业构建低成本、高效率、能随着企业发展而不断完善的物流信息管理系统,满足企业现实需求。文章首先对SOA架构的含义、组成以及优势进行了研究分析,然后对实现SOA架构的核心技术WCF框架进行了详尽的阐述,并对该框架中的关键技术进行了研究,为系统的设计实现做好了理论准备。文章还结合SOA系统不同实际应用场景,对系统中潜在的安全问题和安全需求进行分析,研究介绍了提高系统安全性的相关安全协议和安全技术。在技术准备的基础上,通过对中小物流企业业务需求的分析研究,对系统架构层次和功能进行了详细的设计,并针对系统各层级给出了具体实现。其中,将业务针对SOA架构的要求进行服务化,并针对不同的业务形式特点,区分基础服务、Windows服务和移动扩展服务进行详细的实现阐述。最后,在系统基本架构功能实现和安全性分析的基础上,根据系统特点从存储安全、访问控制、数据传输的角度出发,利用成熟技术,按照系统开销与安全强度最优化的原则,提出了安全解决方案并进行实现,提高本系统的安全系数。更多还原

【Abstract】 With the development of information technology, information technology is playing a more important role in improving the efficiency of enterprises. In the face of the wave of the information technology, logistics enterprises have also constructed the information management systems to enhance themselves in increasingly fierce industrial competition. However, in reality, owing to new small and medium-sized logistics enterprises not only have to face the pressure of surviving, but also are stuck with market expanding, it is difficult to make sure there are adequate human and material resources for constructing logistics information management system. While these enterprises also have an urgent need for logistics information system to improve efficiency of enterprise business operation and management, reduce costs and enhance the competitiveness of enterprises.As said above, this thesis is based on the mature platform of Microsoft’s.NET, we design and implement logistics information management system in lightweight SOA architecture(Service-Oriented Architecture) with utilizing the technology of ASP.NET, WCF(Windows Communication Foundation) and Entity Framework. With the help of features like loose coupling, good flexibility and strong expansibility, we can construct a logistics information management system which has low cost, high efficiency for small and medium-sized logistics enterprises to meet the practical needs of the enterprises, and this system will improve itself as the development of enterprises.First, we analyze the meaning and structure and advantages of SOA architecture, then expounds the core technology for implementing the SOA architecture--WCF framework, meanwhile, regard the research of key technology in the framework as preparation of designing and implementing the system.According to the different application scenarios of SOA systems in practice, we also analyze the potential security problems and security needs of SOA systems, study and present relevant security protocols and security technologies applied to improve system security.On the basis of the technical preparations, by analyzing the business needs of small and medium-sized enterprises, we design the system architecture and functions in detail and give a concrete implementation for each level of the system. The business should be service-oriented based on the architecture of SOA, what’s more, aims at different characteristics of business and distinguishes basic services, Windows services and mobile extension service, and expounds the implement of the triple services.Finally, on the foundation of implementing the basic architecture function and security analysis, we think of system characteristic and stand on the perspective of storage security, access control, data transmission, make use of mature technology, following the principle of optimal system consuming and security degree, put forward a security solution and implement in practice to improve the security factor of the system.更多还原
