摘要
目的:探索场景分析方法在公共卫生概念模型构建中的应用。方法:应用场景分析概念和功能,对公共卫生业务活动各要素进行归类、特化与泛化,探索公共卫生概念模型框架,并应用公共卫生业务实例验证其有效性。结果构建了公共卫生领域信息活动场景,初步形成了公共卫生概念模型框架。结论:场景分析是公共卫生概念建模过程中抽象业务活动、提取模型类及类关联的有效方法。
Objective： To explore the application of scenario analysis in public health conceptual data modeling. Methods： By describing the basic concepts and functions of scenario analysis, and taking the public health conceptual data modeling in China as an example, we rearranged the elements within public health process by classification, generalization and specialization to form the conceptual model framework. Results： Based on the scenario analysis, the public health conceptual data model framework was formed. Conclusions Scenario analysis was a valid and easy-handled method for data generalization, class and class association extraction in conceptual data modeling.
