Taking the mills as an example , it introduces the process of data modeling , analyzes the data depend-ence, presents the implementation of data constraints and programming of the user interface .This method pro-vides the solution for tools management and plays an important role in design and implementation of engineering database .%以立铣刀为例,从数据建模、数据依赖性分析以及约束条件的实现、用户界面编制等方面论述了刀具管理模块在工程数据库中的具体设计与实现方法。分析问题的思路以及采用的方法对于工程数据库的设计与实现具有参考意义。
