Through serial port on PC, VB program exchange data with peripheral devices to collecting data and control equips, the event driven and query communication is briefly introduced by examples. 利用PC机提供的串行端口，可用VB编写的程序与外界设备交换数据，达到数据采集和设备控制的目的，以实例形式介绍了事件驱动和轮询两种通讯处理方式。
CIMS adopt JMS publish / subscribe system as message middleware, realized the asynchronous communication among Agents, because of the Agent character of event driven and the advantage of event communication mode, CIMS adopt the communication mechanism based on event. CIMS使用JMS的发布/订阅系统作为消息中间件，实现了多Agent之间的异步通信。鉴于Agent的事件驱动特性以及事件通信模式的优越性，CIMS采用基于事件的通信机制。
It is based on an event driven based object oriented model. It's components include an interface object model, a process control model and a communication model between user applications. This framework supports static / dynamic customization, thus satisfying End User Adaptibility. 该框架基于一种事件驱动的对象模型，包含界面对象模型、系统流程控制模型以及应用程序间的通讯模型，支持用户对界面的静态／动态定制，满足最终用户可修改性（EndUserAdaptability）。
In synchronization system we developed, the change event of a database system can be captured real timely based on the data driven rules of Event Condition Action, and the consistency among heterogeneous database systems are maintained by the cooperation of some communication agents. 采用事件-条件-动作的数据驱动机制实现数据库变更事件的实时获取，通过多个通讯代理协同工作完成异构数据库间的数据一致性维护。
For the asynchronous communication, a Message Driven Bean ( MDB ), called Event Service MDB, is installed and retrieves the events using JMS mechanisms. 对于异步通信，将安装名为事件服务MDB的消息驱动的Bean（MessageDrivenBean，MDB），并使用JMS机制检索事件。
