This article will explain in detail what the test question bank management system based on struts2 is like, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

First, the current situation and significance of the research (including the background and significance of the topic, the status of research at home and abroad, etc.)

1.1 Research status at home and abroad

At this stage, it can be said that the research on the design theory of the network test question bank system is still in its infancy, and there are still many problems to be studied and explored. For example, in the network environment, how to use network resources to share with you more timely and comprehensively is worthy of our study.

With the popularization of the application of Internet, the network examination question database system has become an important means of teaching examination question management. However, compared with the traditional paper proposition, the quality assurance system of the network examination question bank system is not perfect and perfect. How to ensure the quality of the network examination question bank system and establish an effective network examination question bank system has become an urgent matter now. Up to 2000, the Ministry of Education approved the establishment of online education colleges in 31 universities across the country, but did not formulate relevant policies on how to ensure the quality of online education. In April 2000, the National Education Policy Institute of the United States also published a report entitled "online Education quality: criteria for the successful Application of distance Internet Education". However, these articles (reports) are only descriptive indicators for the evaluation of web-based teaching, but they are rarely concerned with how to organize evaluation, how to obtain quantitative data, and how evaluation data promote teaching. At present, the learning evaluation module in the supporting platform of web-based teaching often contains only the test part, and lacks the corresponding analysis and feedback.

1.2 the purpose and significance of the subject

The online examination question database system has the function of attaching importance to the function of generating papers and neglecting the function of educational measurement. As an educational measurement tool, item bank not only has the function of test question management and test paper grouping, but also has the more important function of collecting test data, statistics and analysis of these test data, finding the problems existing in the test bank, discovering the problems in the teaching process of teachers, and finding the problems in the learning process of students. These questions are hidden behind the test scores. The item bank system should analyze the test data, explore information, and provide teachers with more information about the teaching process.

At present, in most schools, the examination paper process is still done manually by the teacher. Teachers often rely on many years of teaching experience, comprehensively considering various knowledge points, the difficulty of examination questions, referring to previous years' examination questions, drawing corresponding questions from a huge examination question bank, etc., in order to form a qualified test paper, the tedious degree of its task can be imagined. It has greatly increased the workload of the teacher. The use of computer software technology to complete the process from the storage of examination questions to the formation of a qualified examination paper can not only greatly reduce the task of teachers, but also improve the work efficiency of teachers. more conducive to the development of education in the direction of science and technology, automation and digitalization. At the same time, the whole process from the storage of the test questions to the test paper is completed by the computer, and the whole process can be paperless, saving paper and responding to the call of low-carbon life. As the whole process of the system is handed over to the computer itself to complete, the selection of questions is done at random, and the confidentiality of the test paper is guaranteed, which is conducive to the comprehensive coverage of knowledge.

Therefore, a good examination question bank management system is extremely important.

Second, the main problems, key points and difficulties of research (or development)

2.1 main questions (or research content)

This topic mainly studies the design and implementation of the test question bank system based on JSP technology. The mvc development mode of jsp+struts2+mysql+tomcat will be adopted, in which jsp is the display layer of the foreground page, struts2 is the control layer of the system, and mysql is the data of the system. Mvc development mode is the most popular and mature development mode, which is recognized by the public as a development mode that can develop enterprises efficiently and stably.

The test question bank system is mainly divided into two parts, which are backstage and foreground modules.

Foreground module: add teacher users, user information management, add test questions, test question maintenance, test question query, dynamic composition of test papers, test paper management, import and export of test papers. The function of each module has the corresponding function of adding, deleting, changing and searching.

Background module: add administrator, user information management, course management, user information query. The function of each module has the corresponding function of adding, deleting, changing and searching.

2.2 key points of the project

The research focus of this examination question bank management system is as follows:

(1) privilege management between different users.

The authority management of a system is very important, the quality of the design is directly related to the use of the system, how to better set up the relationship between them is very important, for database operation, how to use logical SQL statements to establish a strong relationship between tables, to improve the efficiency of the operation is a difficulty.

(2) Database design: database design is half of the success of the system, and it is related to the safe and normal use of the system.

2.3 difficulties in the subject

(1) in the entity class design: the difficulty is whether the reasonable design of the entity class is related to the system energy, because the entity class is directly corresponding to the data table.

(2) the design of the database table: how to plan the database reasonably and efficiently, maximize the correlation of the data table, make the database meet the higher paradigm as far as possible, and optimize the query algorithm to improve the query speed is also the core and difficulty of the system.

(3) Interface design: how to reflect the core of the system simply and intuitively, and how to establish a simple, beautiful and generous interface is also the difficulty of the system, which requires strong HTML+js ability.

2.4 Features or innovations

(1) the online ticketing system uses Struts2 as the system development framework, which is characterized by the separation of the presentation and logic parts of the software. The Struts framework is composed of presentation logic layer, business logic layer and database layer, which can realize this separation to separate the display part from the logic control. The server application program is used to realize the display part, and the business logic layer is used to realize the flow control of the program.

(2) the system uses java language to solve the cross-platform problem to ensure the security, maintainability and ease of operation of the system.

(3) the system development uses hierarchical development, which makes the maintenance more convenient and the execution efficiency will be improved.

On the struts2-based development of the test database management system is shared here, I hope that the above content can be of some help to you, can learn more knowledge. If you think the article is good, you can share it for more people to see.
