基于框架的数据模型的研究

Research on Frame-based Data Model

城市地下管网管理信息系统是研究地下管线和地上相关目标的存储、检索、统计等工作的，这一系统中有关地上、地下目标的关系相当复杂，因而不适宜用传统的数据模型处理。该文把人工智能中的框架思想引入数据库，提出了基于框架的数据模型，给出了目标描述框架和目标定义框架的定义，并应用这一数据模型实现了地下管网管理信息系统。

Underground pipeline management information system studies the storage, retrieval, statistics of underground pipeline and its relative object on ground,the relationship between ground object and underground object is complicated,and thus it can't be processed using the traditional data model.In this paper, the idea of frame in artificial intelligence is introduced into database, a data model named frame-based is studied and the concepts related to this data model such as object description frame,object definition frame are defined,and underground pipeline management information system is realized using this data model.
