非连接C/S计算模式数据同步解决方案

A Scheme of Data Synchronization Using the Non connecting C/S Calculating Model

非连接客户机 /服务器计算模式是一种较为常见的体系结构。其具体特点是系统中各客户机离线运行 ,只是在合适的时刻进行远程数据的同步。同步要求包括两个方面 ,一是工作站业务数据送入服务器外 ,二是借助于服务器将有关业务数据传送给其它客户机。本文以一个实际的非连接客户机 /服务器系统设计为依托 ,较为祥细地介绍了利用“电子通知对象”进行数据同步的一种解决方案。通过对国内相关资料的检索证实该方案属于技术创新 ,并且现实系统运行正常、良好 。

Non connecting client/server calculating model is a general system structure. The feature of the structure is that every client computer runs out of line. Only at the suitable time will it synchronize with remote data. The synchronization requires two parts: one is that the vocational data of the workstation will be sent to the server, the other part is that the corresponding data will be sent to the other client computers by the server. This paper introduces a practical scheme of data synchronization by using `electronic notice object' after the design of a practical client/server system.It is proved that the system runs normally and is an innovation.
