试题库管理系统的设计与实现 PAGE 36 PAGE 摘 要 试题库管理系统可辅助教师对所教科目的各种试题的题型、知识点、难度等相关资料进行保存、查询等信息管理；并在需要对学生进行测验、评估的时候，从题库中抽取出相应要求的题目，组成一套试卷。 经过分析如此情况，我使用Sybase公司的PowerBuilder7.0开发工具，利用其提供的各种面向对象的开发工具，尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象，首先在短时间内建立系统应用原型，然后，对初始原型系统进行需求迭代，不断修正和改进，直到形成学校管理者满意的可行系统。本文首先简要介绍了开发试题库管理系统的可行性分析，Powerbuilder7.0的功能和特点，然后主要针对系统的设计、组成、用户界面设计、程序设计进行了详细分析，并对系统部分关键性代码进行了讲解，同时对一般系统软件设计的基本思想及工作流程给出了方法技巧。首先在短时间内建立系统应用原型,然后,对初始原型系统进行需求迭代,不断修正和改进,直到形成用户满意的可行系统。 关键字： 试题库 试卷 数据窗口 Abstract Test question storeroom management the system can lend support to the teacher to the category taught of every kind of trys the type, knowledge point, difficulty etc. the related data proceeds keep, search etc. information management; Combine at the time that the demand proceeds to student test, valuation, from for test question inside take outing the correspond requesting subject, constitute a the set try book. Pass by the analysis such the circumstance, I use the Sybase company PowerBuilder7.0 to develop the tool, and make use of its provide every kind of to face to the objects development tool, and particularly is a data window way this a can convenience but the Chiens manipulate the databases intelligence 化 the object, and establish the system in the in a short time first applied prototype, then, proceeds to system of early prototype need on behalf, continuously revise with improve, until formation the school governor be satisfied with of can line system. This text the synopsis introduced the development to try the function of a viability assessment for storeroom the system, Powerbuilder7.0 with the characteristics first, and then primarily aim at the systems design, constitute, customer interface design, procedure the design proceedsed detailed analysis, combine to proceeded to explain in detail to part of and decisive code of system, at the same time the basic thought to design to general system software and workflow give out method technique.
