通过分析数字科技馆对科普资料数字化的特殊要求,对科普资料形成层次关系,据此创建具有相同层次关系的实体类,最后由实体类驱动生成结构上与科普资料层次关系相一致的数据库,从而完成数字科技馆建模过程。这种开发方式符合面向对象的思维开发方式,并方便维护与更新。 By analyzing the special requirements of Digital Science and Technology Museum for the popularization of science popularization data, the hierarchical relationship between popular science popularization materials is formed, and entity classes with the same hierarchical relationship are created accordingly. Finally, entity databases are driven by the entity classes to be consistent with the hierarchy of science popularization data Digital Science and Technology Museum to complete the modeling process. This development method is in line with the development of object-oriented thinking, and easy to maintain and update.
