describes how to perform asynchronous database operations using an api that is modeled after the asynchronous model used by the . net framework 描述如何使用api执行异步数据库操作,该api在.netframework所使用的异步模型之后建模。
in the more complex asynchronous model, your application does not block while waiting for requests and each request is processed in its own execution thread 在更复杂的异步模型中,应用程序在等待请求时不阻止,并且每个请求在其各自的执行线程中处理。
mobile agent, which has lots of advantages in distributive computing or mobile computing ( for example, the use of mobile agent may decrease the amount of communication, and communicate by asynchronous model . ), 而源自于人工智能的移动agent是人工智能技术与网络技术相结合的产物,其在分布式计算或网络计算中有许多特有的优势。
finally, a prototype named ecws ( electronic cooperative work system ) is implemented . it is an internet-based system for geographically dispersed teams to collaborate over the internet in both synchronous and asynchronous models for the purpose of integration in design and manufacturing 最后,本文综合运用上述研究成果,成功设计,开发了一个支持协同产品开发的系统原型ecws(electroniccooperativeworksystem)。
basing on the model of architecture, we design a based-on mobile agent information-searching environment . the traditional search-engine searches information online by a method based on client / server, and keeps gigantic information in server information warehouse; it also completely relies on network s performance, and it does not support transmitting information by asynchronous model . so we request a personalized intelligent information-searching system 绝大多数传统搜索引擎都是基于客户服务器模型的在线搜索模式,并且在服务器后端维持着预定义、海量的信息数据库,这种结构对信启、数据库和网络存在过多的依赖,并且搜索引擎不支持结果的异步传送,因此迫切需要一种个性化、智能化的新型信息发现系统。
