动态升级在MIS系统中的实现与应用

Implementation and application of dynamic upgrade technique in MIS

目前困扰MIS系统发展的一大问题是没有成型的自动升级技术,所有客户端的升级只能通过手工操作。从工程角度出发,提出实用的动态升级技术,采用shell技术和文件压缩技术,解决了管理信息系统客户端维护中可升级性和可维护性差的问题。论述了动态升级技术的抽象模型和结构、在动态升级过程中的文件传输和压缩以及主处理流程。给出动态升级客户端FTP的实现方法,以及在文件传输过程中压缩、解压缩算法的实现。

At present what hampers the development of MIS is that no formed dynamic upgrade technique and all the client upgradings must be done by hands. The practical dynamic upgrade technique was proposed from the view of engineering by using shell technology and file compressing technique, and the problem of bad upgrading and modification in client maintenance in MIS was resolved, The abstract model and structure of dynamic upgrade technique, file transfer and compressing and main flowchart were explained. It shows the implementation in client dynamic upgrading and the implementation of compression and decompression algorithm in file transfer.
