本系统的设计题目来自于镇江国恩电脑公司。为了能够让计算机的销售等脱离手工的操作，让公司各部门能够更高效的运转，资源能够更为合理的利用。公司要求系统实现库存管理、销售管理、系统维护等功能。在公司编程人员及指导老师的帮助下，我选择了原型法，利用Powerbuilder 8.0作为开发工具，在Windows Server 2000 + SQL Server 2000 平台上来开发该信息系统。经过一段时间的实习与调查，首先我建立了一个简单的初始模型，然后根据公司不断提出的新要求和建议，对模型进行反复的修正，最终迭代出满足系统各方用户的模型，形成了完整的计算机销售管理系统。
This system is a typical application of management information system（MIS）,which mainly used to deal with the problem of the sales and inventory management in the small company selling PC. It needs to build up the database and application to develop this system.
The design title of this system comes from Zhenjiang guoen computer company .In order to help businessman to out of hand making, make good use of the resource and make working more efficiently, the system must have the sales and inventory management. In this system specialization book , the introduction detailedly the design process and development step of system , for the maintainability after this system , I add the important code among thesis , and in order to let customer give play to the ability have rendered great service of design time the use , I still regarded the example to introduce with the some typical window operation
This system implementation the merit abilitys such as inventory control and sells management and system maintenance etc , at the same time , I specially designed the prompt fence for nature directly perceived of convenient nature and the visual sense of operation , in order to solve the utilization ratio of big or small space of display , very good basically handle of this system program respectively controls in the window piece the dimension , position and problem that changes and changes of script along with the window size
