The fourth chapter is the design and realization of the system using object - oriented method and introduces the usage of the design pattern in this paper 第四章阐述了按照面向对象的方法对系统进行的需求分析与设计，并介绍了设计模式在系统实现中的应用。
Because the object - oriented method simulate the world from internal structure of objects , its developing procession fit the system practicality need better 因为面向对象方法从内部结构模拟世界，更符合人类认知世界的过程，其开发过程更符合系统的实际需求。
The paper put forwards one kind of system modeling procedure by deploying cmm software procedure , applying object - oriented method and using uml modeling language 本文提出了一种应用cmm软件过程、运用面向对象的方法、使用uml建模语言进行系统建模的过程。
Etc . mechanical cad system developed with structure method has bad readability , expansion and maintenance , development , object - oriented method provide a new software developing method 采用结构化方法开发的机械cad系统可读性、可扩充性、可维护性都很差。
The object - oriented method based on uml is more available to enhance the expansion and maintenance compared with structure method and common object - oriented method 相对于结构化方法和一般面向对象方法，基于uml的面向对象方法更能提高机械cad系统的可扩充性、可维护性等。
Design the process of mechanism kinematic simulation . build the scene of kinematic simulation and relize the visualization of simulation by object - oriented method 设计了机构运动仿真的系统流程，运用面向对象的设计方法，建立了运动仿真场景，实现机构运动过程的可视化。
The article firstly constructs the calculation model by object - oriented method , and then presents basic part and multiple optical part algorithms 该文利用面向对象分析方法构造出对象关联模型，建立了一种光路计算的关键算法模型，它由基本算法模型和多光学零件的算法模型组成。
Road environment , traffic environment , traffic control and each model are constructed with object - oriented method . this paper concludes the achievements of traffic simulation models 在系统建立过程中运用面向对象的方法描述道路环境、交通环境、交通管制及仿真单体模型等。
But these custom object - oriented methods of any type are reusable , while procedural code , especially that using jdbc , has to be hand - crafted to optimize it to the scenario 这些自定义的面向对象的方法都是可重用的，而流程化的代码，特别是使用jdbc ，将不得不针对场景来手工编写。
The object - oriented methods were briefly introduced first in the paper , and then the author explained how to analyze and design a lab management system by using the kind of methods 摘要首先对面向对象方法进行简单介绍，然后说明怎么使用这一方法来分析和设计一个实验室管理系统。
