This mrp system also uses distributed architecture . the logic part of program is deployed in the application server , which makes the mrp system have rapid response . openness and meet the requirement of group corporation 本文从mrp系统的建模、 mrp系统的体系结构和mrp系统的实现三个方面来讨论如何使mpr系统满足上述要求。
The more applications evolve into networks of interacting components and services , the more important it becomes to consider the potential performance issues that typically arise from such distributed architectures 交互式组件和服务网络中包括越多的应用程序，就越需要考虑潜在的性能问题，这通常是由分布式体系结构而引起的。
In such environment , the related tasks are executed at speed and we can monitor the running tasks . the background the wms ' s change from the c / s architecture to web - based , browser / server distributed architecture 在这种技术背景下，由最初的c s体系结构的集中式工作流管理系统也逐渐向基于web ，构架于browser server体系结构的分布式工作流管理系统转化。
In chapter two , the two popular distributed architectures - corba and com / dcom are compared . the limitation of com / dcom and the robust of corba are clarified . then the mutual complementarities of the corba and java are given 第二章对两种分布式系统规范com dcom和corba进行了比较详细的比较，阐明了com dcom分布式规范的局限性以及采用corba规范的鲁棒性。
The message and agent service is correspondence service layer of the system , which is the concrete realization of distributed architecture . and we propose message object model based jms and the realization of the two kinds of message mechanism 消息和代理服务是整个系统的通信服务层,是分布式体系的具体实现,在此我们提出了基于jms的消息对象模型及两种消息机制的实现。
Now , the web techno1ogy is used wide1y , and the web - - based three - - tier distributed architecture , i . e . three - - tier b / s architecture , has the advantages which are the disadvantages in cl ient / server mentioned above 而基于web的三层分布式应用正好克服了传统网络管理体系结构的不足之处，这种三层b s结构的网络管理体系具有使用简单，软硬件要求低，便于移动管理的特点。
In simple terms , the grid is a distributed system for sharing resources , while an soa is a distributed architecture most concerned with service interoperability , easy integration , and simple , extensible , secure access 使用简单的术语来说，网格是一个共享资源的分布式系统，而soa则是一个分布式体系结构，后者最关注的是服务的相互操作能力、易于集成、简单性、可扩展性以及安全访问的特性。
Firstly this paper discusses confine of conventional distribute processing of logistics , then set forth several current popular distribute architecture and techniques , and analyse its " good qualities and shortcoming and operation of one another 本论文首先论述了传统的物流信息系统分布式处理的局限性，阐述了现在流行的几种分布式体系结构及其技术，分析比较了它们的优缺点和互操作性。
In this paper , after the analysis of limitations of systems in which conventional c / s pattern is adopted , j2ee model and features of multi - layer distributed architecture are discussed in detail . the key technologies of j2ee are also researched , which are used in the final system 本文在对传统的c s模式的局限性进行分析后，讨论了多层分布式结构技术的特点和j2ee模型，并对系统设计中的一些关键技术进行了研究。
It can take advantages of dicom rt to perform qa / qc between different institutes there is no doubt that the trend not only in radiation therapy , but also in medical information has increasingly moved toward digital and distributed architecture Pacs （ picturearchivingandcommunicationsystems ）的应用发展和数字化医院的建立势在必行。现代医疗体系要体现“以病人为中心”的指导思想必须从加强管理、提高医疗质量着手。
