目前,国内外高校图书管理信息系统的研究与开发已经达到较好的水平,然而,这些系统主要面向的是整个学校,还难以应用到以系为代表的中层部门,突出表现在手续繁琐、控制过死,缺乏面向中层的特殊功能,同时又有影响系统性能的大量面向全校的功能。随着中层部门图书资料的迅速增加,如果图书资料采集和录入还必须等待学校统一进行,会导致大量最新资料因信息采集不及时而无法借阅。从管理方面看,中层部门因使用对象是本单位员工,其管理方式已经不像学校管理那样重点在于图书安全和控制,而要求管理更灵活、查询更方便,讲究的是资料利用效率。因此不能简单的将学校图书管理系统移植到系级等中层部门中来。要解决上述问题,应借鉴学校图书管理经验,并结合工作实际,开发出适合中层部门实际需要的图书资料管理系统是非常必要的。 本课题结合枣庄学院中文系资料室的图书管理现状和应用需求,有针对性的开发了“基于VB的图书信息管理系统”。其总的设计目标是实现资料室图书管理的系统化、规范化和自动化,以及对图书资料的集中统一管理。该系统开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。通过分析用户需要,在后台服务器端,建立了合理、规范的数据库结构,不同数...
At present, R&D of the domestic and foreign university library management information system has reached a good level. However, these systems are mainly for the entire school, with complex procedures, over-control, lack of special functions for the middle sectors and a large number of useless functions, they are difficult to be applied into the middle sectors represented by the departments. Moreover, books and materials of middle sectors are sharply increasing. But the collection and record of middle sector (2011-09-09, Visual Basic, 7122KB, 下载14次)
