You can leverage the power of db2 as well as remote data sources , and gain from the transparency , heterogeneity , high function , autonomy , extensibility , and optimization features that such a federated system enables 您可以利用db2和远程数据源的威力，从联邦系统所支持的透明性、异构性、高功能、自治性、可扩展性以及一些优化特性中受益。
It is because of the distributed , opened and heterogeneous of internet . at the same time , it makes users more and more difficult get information well and truly , i . e . " rich data poor information " Www资源的迅速膨胀固然得益于其内在的分布性、开放性和异构性，但也正是这一点，使得用户在网上迅速、准确地获得所需信息变得越来越困难。
This model divides the network into reasonable domains , to scale down the whole networks ; and it utilizes the diversity of node , to make the network that is made up by the interface nodes more comparatively stable 该模型将网络划分成适当大小的域,降低网络的整体规模;并利用节点的异构性,使接口节点组成的非结构化网络处于相对稳定状态。
Using the interface users do n ' t need to consider the problem about model heterogeneity , data extracting and combination , etc . . the problem of data integration is one of the ad hoc old problems in database community 数据集成平台的作用是提供一个访问异构数据源的统一接口，使开发人员不必考虑数据模型的异构性、数据抽取、数据合成等问题。
With the fast development of software technology and internet , the traditional two - tier client / server structure cannot meet the requirement of distributing , expansibility and heterogeneity in enterprise computing 随着软件技术和internet的迅猛发展，企业信息系统原有的c s结构越来越不能满足企业计算在分布性、可扩展性和异构性等方面的要求。
We improve the design of the generic component model and component wrappers , meanwhile , we implement two kinds of component wrappers . generic component model and component wrappers are important aspects of the composition model 构件包装器的主要功能是屏蔽构件的异构性，以一致的方式表示构件及其特征，类属构件模型提供了构件包装器接口的定义。
With the development of the computer and network technology , there are high degree of heterogeneous environments in the hardware platforms , operating systems and software development environments of distributed object computing system 随着计算机及网络技术的飞速发展，使得分布实时系统中硬件平台、操作系统、软件开发环境均存在很大程度的异构性。
Combined with the design and development of client evaluation subsystem of crm , this thesis brings forward web service solution to the problem of data distribution and plat heterogeneity , which would be faced when the crm system is developed 本文结合crm客户评价分系统的设计与开发，提出用webservice解决crm系统发展将要面临的数据分布性和平台异构性问题。
Agent technology has characters of self - determination , asynchronous operations , society nature , communication and isomerism , it will be the most appropriate technology to achieve parallel multitask 近年来兴起的agent技术具有自主性、异步并行性、交互性、通讯性和异构性等行为特性，由于这些优点， agent成为在实时控制系统中实现并行多任务的最佳技术手段。
And on the flat roof on higher layer , it communicates with the sub ? ystems through the sub - system interface . the standard components on the lower layer are visible and unheterogeneous to the higher layer , and thus shielding the heterogeneity 这样，对于上层来说，这些标准化的泛子系统是可见的，无异构的，从而屏蔽了子系统的异构性，从而可以在上层集成平台完成集成工作。
