摘要
本文从系统不同的处理任务出发,化分了 MIS-MMS 的逻辑结构。以矿井测量子系统为例,对系统的数据流程和各职能模块间的控制关系进行了详尽的阐述,并对建库实体模型进行了规范化处理,减少了数据冗余。
In this paper,the logical structure of MIS-MMS is divided according to different procc ss missions.According to the cxamplc of undcrground survcy,the data flow of system and control relationship of every functional module are expounded and the entity models for base generation is normally processed,therefore,redundant data are decreased.
