Absrtact: In the modernized education, the question Bank, the examination paper construction is the teaching activity important constituent, the traditional hand-made examination paper often appears the content similarity, the knowledge point is unreasonable as well as the clerical error, the printing mistake and so on. Therefore, for the information Bank management of the development of the database management system, the system is based on the B/S model of test questions, download questions and import questions in one, where the databases using MySQL, the front page display is JSP, development tools are eclipse, the server open source security tomcat. In this paper, the overall design of the system, database design and function module design are discussed in detail.

1 Preface 1.1 The current situation of online question Bank management system

At this stage, it can be said that the research of the design theory of the network question Bank system is still in the primary stage, there are many problems to be researched and explored. For example, in the network environment How to use the network resources for more timely and more comprehensive to share with you, are worth our research.

With the popularization of Internet application, the network question Bank system has become an important management method of teaching questions. However, compared with the traditional paper propositions, the quality assurance system of the network question Bank system is not perfect and sound ....

1.2 The significance of online question Bank management system

The online question Bank system has the function of attaching importance to the group volume and neglecting the function of educational measurement. As an educational measurement tool, it is not only the function of question Management and group volume, but also the most important function is to collect the test data and analyze the test data, find the problems in the problem, discover the problems in the teaching process, and discover the problems in the course of the students ' learning.

3 System Feasibility Analysis 3.1 Feasibility Analysis 3.1.1 Economic Feasibility
