摘   要
 企业实践是学院教育中的最重要的环节之一，为此我院安排为期半年到一年的企业实践。由于我院采用完全将学生放入企业的实习方式，而且实践企业既有学院联系的也可以自己联系，这样就使得企业数量多，且地点分散，每个单位学生少，要做到对企业实践的全程跟踪就会加大老师的工作强度，分散老师的日常教学精力。基于这些情况，需要企业实践信息交互平台来提高工作效率，完善教学管理。
 以我软件学院企业实践需求设计了本系统。本系统完成企业信息，学生信息，校内和企业导师信息的注册和维护，实习阶段汇报表，实习阶段检查表和实习鉴定表的填写，信息发布等，这些都是在企业实践过程中企业，学生，校内导师和企业导师共同完成任务，以便实现信息的高效管理和企业实践的有效跟踪管理。
 本文将介绍课题来源、研究意义和目前情况，概述系统需求，阐述系统体系结构，然后从开发环境、数据库设计、系统框架、流程控制、模块设计等方面详细说明整个开发设计过程，并说明本系统应用到的一些关键技术。

The Design and Implementation of
 Enterprise Practice Information Exchange Platform

Abstract
 Because practice in business enterprise is one of the most important projects in our approach to our school''s education goal, students are dispatched to different business enterprises for about six months to one year to complete it. Our students stay in the companies totally during their business practice. Besides, there are also many companies contact with students directly, although most of them contact with our school. This comes to the situation that there are a large number of companies with only a few student, and they are at different sites in varies distances. It is difficult for teachers to track the practices all the time, and it will decentralize the teachers'' energy. According to these situations, we need a business enterprise practice information system to improve our teaching management level.
  I design this system for our school''s use .In this system, we can register and maintain the companies, students and the teachers both in school and company''s information. We can fill in the reports about business practice and also we can deliver information to everybody through it. These are tasks should be completed by companies, students, teachers in school and teachers company together, so as to make a efficient management and tracking of the business enterprise practice.
     In this paper, I introduce the source of this task, the significance of it and the research situation, the requirement and the architecture of this system, and then give a whole design and development process from development environment, database design, system architecture, process control and modules design. At last I introduce some key technologies used in this system.
