【摘要】 提出了软件系统中的可变数据编码问题，给出了数据编码的树形结构的例子．并提出了数据编码的外码、内码、定码的概念．为使软件系统不受数据编码变动的影响从而具有适应性、可维护性，还提出了可变数据编码管理系统用于辅助编码维护；并论述了其原理、功能和接口．更多还原

【Abstract】 The problem of variable data code in software,the example of tree structure of data code and concepts of outer code,inside code and fixed code are presented in this paper. In order to make software unaffected by the changing of data code and thus to have adaptability,maintainability,th variable data code management system is proposed to maintain data code. It’s principle, functions and interface are discussed.更多还原
