可维护性

Want those who improve software to be able to safeguard gender, alterability, design low coupling, tall cohesion with respect to what must let us, also must accomplish duty drive to design .

要提高软件的可维护性、可变更性，就必须让我们的设计低耦合、高内聚，也就必须做到职责驱动设计。

Mining design patterns from source code is a very important technology for improving the intelligibility and maintainability of software.

从系统源码中挖掘设计模式对软件的可理解性和可维护性具有重要意义。

Due to its high reusability and maintainability, component-based software has been the focus of software development in recent years.

基于构件的软件工程因其具有较高层次的可重用性和高度的可维护性，因而成为了近年来软件开发的热点。

That greatly improves the reusability and maintainability of the system.

这使得该系统的可复用性和可维护性也得到了很大的提高。

Version control is an important way to improve the maintainability of software.

版本控制是增强软件可维护性的重要方法，但目前常用的版本控制机制缺乏对需求的可追踪性支持。

Intelligent answering based on answer library realizes the automatic answer of user＇s questions based on nature language with the Chinese segmentation algorithm based on maximum matching method.

系统的实现基于J2EE三层架构体系，在中间层采用先进的MVC设计模式思想，实现页面显示与业务逻辑的分离，有效提高系统的可维护性、可扩展性和可复用性。

The qualities of the two systems in usability, maintainability and transportability, are fully guaranteed.

在各级测试的基础上，两个系统的质量如可用性、可维护性和可移植性等得到了充分的保证。

But most of these systems developed under Windows OS are stand-alone software using different database, therefore they have many shortcomings such as poor transportability, working inefficiency, bad scalability, bad maintainability, and etc.

但目前使用的科研管理系统大多是早期开发的Windows操作系统下的单机版软件，使用不同的后台数据库，普遍存在着可移植性差、工作效率低、可扩展性差、可维护性差以及部署麻烦等缺点。

In design of this text database, h**e adopted the design method of software, the clear show data are stored and adjusted after adopting tools such as the data flow diagram, procedure flow diagramed. Security system is stalwart, the maintainability, and expandability.

在本文数据库的设计过程中，采用了结构化设计方法，利用数据流程图、程序流程图等工具清晰的展示了数据存储及调用过程，保证了系统的健壮性，可维护性，可扩充性。

And then gives a framework of devloping E-Commerce system based on J2EE. The framework has multilayer architecture of J2EE, and reuses many functions of J2EE.

该框架采用了J2EE 的多层体系结构，并且尽量多的重用了现在J2EE 系统中的许多功能，可扩充性好，具有良好的移植性和可维护性。

This one mode pays close attention to network credence foundation of the businessman very much.
