摘要
概念建模是提高需求分析质量的重要技术。针对分布式多媒体信息系统概念建模面临的系统的异构性、海量数据和格式的差异性、时空的不一致性问题,本文介绍了信息系统常见概念建模方法,包括结构化概念建模、面向对象概念建模和本体概念建模,在此基础上,采用基于UML的面向对象概念建模法对分布式多媒体网络教学系统概念模型进行描述和表达,并建立了UML类图到本体模型的转换。
Conceptual modeling is the important technology to improve the quality of demand analysis.There are problems in the distributed multimedia information system,which include heterogeneity,different forma of mass data and time-space inconsistency.This paper introduces some common conceptual modeling methods such as structured conceptual modeling,object-oriented conceptual modeling and ontology conceptual modeling,then describes and represents the concept model of the distributed multimedia internet teaching system using UML class diagram,and establishes the translation of UML class diagram to ontology model.
