【摘要】 随着网络技术的发展,计算机渗入了工作生活中各个领域,它的广泛应用给经济和社会带来深刻的变革。而计算机技术的不断革新,使得我们必须跟上信息化建设的步法。作为北京大学管理工作的一个重要组成部分——科技成果信息管理,所涉及的信息量越来越大,数据越来越繁琐,目前应用的基于C/S系统的北京大学科技管理系统已经不能满足现有的数据管理和存储,需要开发一套更加方便、更加快捷的管理系统来适应新的管理方式。基于B/S结构技术和数据库技术良好的结合,可以使得我们使用信息系统更加方便,无论何时何地,都可以通过网络连入到系统中,这种变化也使得开发可以具有统一的MVC模式,即三层系统的一种模式,模式的统一往往意味着开发的高效和成本的降低。因此,开发一套基于网络的、方便访问和管理的综合信息系统,是解决当前问题的首选。针对北京大学科技成果管理的实际情况,提出了以数据库设计和WEB应用设计为基础的MVC模式的管理信息系统开发方案。所做的主要工作如下:对北京大学科技成果管理的需求、对各种用户的需求进行调研,规划系统的各种目标,确定搭建本系统需要的软硬件环境。根据实际要求将本系统划分为五大模块:专家库模块、科技成果库模块、科研项目模块、补录与数据导入模块和邮件发送模块。针对北京大学科技成果信息管理系统的一些特有特点,设计出数据库各种表及其结构,各种表之间关系。通过MySql数据库支持技术来优化一些数据库运行时的性能,使用数据库连接池技术来提高存取数据的效率,建立必要的索引来提高数据的查询速度,设计存储过程来减少网络流量,提高系统的执行效率。针对北京大学科技成果管理的需求,确定系统框架和包含的具体功能模块,详细阐述了各个模块的实现细节。本系统建立后能够满足北京大学科技成果管理的需求,借助计算机技术、网络技术,建立基于网络环境的管理信息系统,使得北京大学科技成果管理工作信息化。本系统的实现,为北京大学提供了一个科技成果信息和科技成果管理人员的管理平台,使得北京大学行政管理人员提高了北京大学科技成果管理水平。

【Abstract】 With the development of network technology, the development model ofmanagement information systems has changed a lot since B/S architecturetechnology and database technology makes a good combination of each other, thischange allows us to use information systems more convenient, we can connect to thesystem through the network anytime we want, this change also lets the developmentof system has a uniform MVC pattern, developing a system with unified model meansefficient and cost reduction, the fact that past C/S based system can not continue tomeet current data management and storage needs. So, Science and TechnologyDevelopment Department of Peking University should develop a B/S based system,which easy to access and can manage data well. Based on the fact of STDD of PekingUniversity, we use B/S and database technology, combined with the MVCdevelopment model to build a practical information management system. Thefallowing are details:Understanding the needs of Ministry of Science and Technology, understandingthe needs of various users, planning various goals of the system, determine hardwareand software environment needed. Based on the actual requirements of this system,the system is divided into five modules: expert database module, results librarymodule, research module, makeup and data import module and mail module.Aimed at some unique features of information management systems for PKU, wedesignd and structured various tables and kinds of relationships between tables of thedatabase to fulfill the requirements. We use MySql database technology to supportand optimize the performance of the database, use the database connection pool toimprove the efficiency of accessing data, building the necessary indexes to improvequery speed of data, stored procedures is designed to reduce network traffic, all thesemeasures are taken to improve system execution efficiency.Based on requirements of one-stop registry, data sharing whithin the campusnetwork, user centrolised by STDD of Peking University, we determine the systemframework and specific modules, and we describe each module in details. At last, weuse JSP+JDBC series of techniques to complete the system implementation.The system we build can fulfill STDD of Peking University’s requirement, theuse of computer technology, network technology, the establishment of Web-basedenvironmental management information system, making Peking University’sResearch and Management in the forefront. The implementation of this system,provides a very good information and research platform for STDD of Peking University, the user can manage their task very easy and convenice, could make apositive effection of research work.
