摘要
为了支持企业历史信息等与时间特征相关的建模,提出了包括日历对象、时间属性域类型、时间戳等在内的基本元模型。利用这些基本元模型,建模者可以在现有企业模型的基础上实现基于时间特征的时态化扩展建模,从而提高企业模型及其应用系统的弹性。
To support the modeling of time-related information such as historical information, an enterprise temporal modeling was proposed, involving calendar objects, time attribute domain types, and timestamps. With these concepts and their meta-models, model designers can build temporal enterprise models based on the current snapshot models so as to increase the flexibility of models and information systems.
