This paper introduces how to use the Unified Modeling Language to design the relation database, merging the process of designing database and the process of designing the whole software, providing a new and recommendable method for database designing. 介绍了如何应用统一建模语言来设计关系数据库,该方法把设计数据库的过程与设计整个软件的过程结合起来,提出了一种可值得参考的数据库设计新方法。
Then go through with overall design, applying three-layer application architecture, object-oriented methods, unified authentication and authorization management to design the database of comprehensive underground pipe network construction and underground pipeline management and analysis system in detail. 然后进行系统总体设计,采用三层应用体系结构、面向对象方法、统一认证与授权管理,对地下管网综合数据库建设和地下管线管理与分析系统进行详细设计。
The Unified Design Thought of the Foundational Topographic and Cadastral Database 一体化基础地形地籍数据库的设计思想
Combined with the database requirements for expansibility in ship power electric simulation training system, UML ( Unified Modeling Language ) is used to design and implement the database. 结合船舶动力电力仿真训练系统数据库对扩展性的要求,采用UML(统一建模语言)对系统数据库进行了设计并实现。
Based on the key technology, Unified Modeling Language ( UML ) is used to design the model of RTDB. The general Real-Time database model can define the information of table and field and can describe the relation of tables by setting the key words of table. 在此基础上采用通用模型语言(UML)设计了通用实时数据库的存储模型,实现灵活地对实时数据库的表、字段信息定义以及通过对表的主键的设置,实现表的关系的定义。
