【摘要】 介绍一个典型的赤潮监测网络的数据库建模和系统实现,重点是数据库的逻辑建模,以及ERA模型在逻辑建模中的应用。在建模过程中,应用了数据库规范化理论,减少了冗余数据,提高了系统的可维护性。最后,简要说明了建立在数据库建模基础上的赤潮监测网络的系统实现。更多还原

【Abstract】 This paper introduces a database modeling of a red tide Monitoring Network. It focuses on the application of ERA model in logical modeling. The theory of normalization is used to reduce the redundant data of the database and promote the maintenance of the system. Finally, it gives a brief direction about system realization based on database modeling.更多还原
