Our code was realized adequately reduplicate using and greatly reduce the exploitation time and work force due to we use the MVC model to explore.

由于本系统采用了MVC系统架构模式进行开发，在开发过程中代码实现了充分的重用，可分层次同时开发，极大地减低了开发时间和工作量。

To in boat letter this kinds of situation, not divide stage course project and for setting up on the each period of stage there aren't thought , stage of control goal, this text has proposed the control goal model of the quality of stage of course of development based on milestone innovativly, model this divide course that information system develop into feasibility analyse , encode , integrate , is it wait for 9 stages to test, and has confirmed the control goal of quality for each stage , has set up two milestones of quality control , navigate letter course stage that information system develop row , is it have achievement may be examined each period of stage to make, a quality goal is controlled , avoid developing the transparency of course and quality control defect not high of visuality like this.

针对中航信的这种情况，受工程项目对过程进行阶段划分并为每个阶段设立阶段控制目标的思想启发，本文创新性地提出了基于里程碑的开发过程阶段质量控制目标模型，该模型将信息系统开发的过程划分为可行性分析、编码、集成、测试等9个阶段，并为每个阶段确定了质量控制目标，设立了两个质量管理的里程碑，将中航信信息系统开发的过程阶段划，使每个阶段都有成果可以检验，都有质量目标进行控制，这样就避免了开发过程透明度和可视性不高的质量管理缺陷。

It contains information system empolders background, system analysis, system design,system put in practice and system vindecates all lifecycle.

它涵盖了信息系统的开发背景、系统分析、系统设计、系统实施、以及系统维护的信息系统开发的整个生命周期。

On the basis for discussing the support environment,developingmethods and tools of the Web application systems,this paper presents a proto-type system of a Java-electronic shopping system, which can provide a frame-work of a Java-based electronic shopping system or electronic commerce systemfor reference.

在研讨Web应用系统支持环境，开发方法及工具的同时，本文采用Java开发了一个网上购物的原型系统，旨在对网上电子商务及网上购物等Web应用系统的研究开发和应用提供一定的参考作用。

Based on the analysis of the embedded system and embedded software development process and memory management, we researched the unitary requirement and particular requirement for memory management module of embedded software development platform. Then the infrastructure of communication industry oriented embedded software development platform had been described, and the design ideas of memory management module of embedded software development platform had been put up: kernel data section management, process stack and data section management , UB section management , high mapping address management and specific implementing code to realize the application, release, protection, leak detection, system information providing of memory.

本文在分析了嵌入式系统及嵌入式软件开发过程及其内存管理的特点的基础上，研究嵌入式软件开发平台的整体需求和对内存管理模块的具体需求；描述了面向通信行业的嵌入式软件开发平台的整体结构，具体提出了嵌入式软件开发平台内存管理模块的设计思想：核心数据区管理+进程堆栈与数据区管理+UB区管理+高端映射地址的管理，和具体实现代码来实现内存申请与释放、内存保护、内存泄漏检查、提供系统内存信息等功能。

The system is base on Spring by integrating Struts and Hibernate.First,the paper explained for using Spring and advantage of using Spring;next,analyse system's function,devide function module,choose development tool and implementation technical,design database module on the base of user's demand and system environmental;then,make implementation details for the modules of system,emphatically expound some technical,like use of Spring Ioc and AOP,certification model of licence,document manage base on Jacob and dynamic function calls;last,test the system and give advice to improve the defects.

本系统是基于Spring框架构建的J2EE系统，并整合了Struts和Hibernate框架，文章首先论述了采用Spring框架开发的理由和采用该框架的好处；其次根据用户需求和系统使用环境，对系统功能进行分析，划分出各个功能模块，确定了开发工具和实现技术，并设计出数据库模型；然后对系统各模块进行详细设计，着重阐述了Spring IoC和AOP的使用、许可证认证模式、基于Jacob的文档处理和函数的动态调用等关键技术；最后对系统进行功能测试，并提出对一些不足之处的改进思路。

An engineering framework system to supp...

PDM层提供了有效的集成信息环境；开发工具层由许多单独的产品开发软件组成，这些软件封装在 PDM系统中；根据建立的过程模型，过程管理层仿真和控制产品开发过程，并在工程框架系统中有效地实现了产品和开发过程集成

Following these, the paper use the idea of the rapid development of the control and scheduling system and three developed tools in Desktop FMS. The application verifies the feasibility and availability to shorten the development time, reduce costs, and improve the reconfigurations of the control and scheduling system.
