Today, with the rapid development of information technology, every user or staff member of a company has to do a lot of data processing work every day, which is complex and error-prone. This situation requires us to have new information management methods to improve our working methods and environment. The new database management technology requires us to refer to the resources and information management mode of network database when processing data, so as to better improve the efficiency of information management.
1 Characteristics of computer network database technology
A computer database is a collection of data, including files and records. The function of database is to store data, and it processes data through client and server. First of all, it realizes the structure and independence of data storage structure. Secondly, the data in the computer network database can be shared. In addition, the computer network database has strong independence. Independence here includes independence in logical sense and independence in physical sense. The independence of computer database greatly increases the security of data, and the corresponding data and programs will not change qualitatively because of changing the corresponding data, so the programs can be effectively prevented from being destroyed. Finally, the database is controlled and managed by DBMS. Only through DBMS can computer network database realize data control and resource sharing, and enable multiple users to use database resources at the same time and in different places. The main features of database technology are data organization, data enjoyment, data independence, controllable redundancy and data flexibility. Organization means that the data in the database is not disorderly, but an interrelated unity; The enjoyment of data is its main feature and the important purpose of establishing a database; The independence of database is reflected in its own logical independence and physical independence; Among them, logical independence means that when the overall logical structure of the database changes, its internal application programs will not change, and the corresponding programs do not need to be modified when changing data. For example, the controllability of redundancy means that the design manager can take necessary data processing methods according to the designer's wishes to effectively control the data; Flexibility means that the database is not only used to manage data? Warehouse? , but also has many management functions.
2 Computer network database technology in information management application status
At present, computer network database technology is developing and progressing, which is more closely combined with simple computer technology. First of all, its application scope is getting wider and wider. Mainly reflected in: first, the combination of computer technology and database has a good development prospect and a very broad existing and potential market; Second, the application scope of computer database technology has been expanding, involving all walks of life in China, such as industry, agriculture and commerce, which has continuously improved the efficiency of information management; Thirdly, the continuous development of computer database technology provides technical support for information management in many industries, which greatly promotes the further development of related industries and the improvement of management level; Fourthly, computer database technology has high security and is widely used in all walks of life, and has achieved good practical application results. Secondly, the application of computer network database technology in information management presents a good development trend. Whether the computer database technology is good or not is clear at a glance in practical application. Research shows that its application and development also play an important role in promoting its own development. In addition, the development of database technology is closely related to its application in information management. Third, the security of computer network database technology in the application process is constantly strengthening. It is precisely because of the enhancement of security that it highlights its advantages in information management applications and effectively ensures its due effectiveness in information management. After solving the problem of traditional information management mode without information management, computer network database can no longer provide fast, efficient and safe information management guarantee, and meets the needs of modern information management system.
3 computer network database technology in the application of information management improvement measures
(1) Strengthen the security supervision of computer network databases.
Security is the most important link in information management, and ensuring the security of the database is the overall demand of the development of the database itself and the modernization of information management. At present, network database technology still faces a series of network risk factors, which may bring huge losses to information management. Therefore, in the next information management work, we should focus on the security of network database technology, find problems, solve them in time and effectively, and avoid losses.
(2) Strengthen the combination of system theory and practice of computer network database technology.
Computer network database technology is developing with the development of information technology and computer network. Therefore, it is necessary to introduce new scientific research achievements into specific information management work, base on practice and give timely feedback, so as to comprehensively enhance the pertinence and practicability of its theoretical research.
(3) Reduce the cost of user management.
Reducing the cost of user management is an important factor for the success of computer database technology in competition. It can provide better and more convenient services for information management, and users can enjoy more comprehensive and personalized services in the database.

Fan Wener, Computer Major: Reform Strategies of Computer Basic Teaching in Secondary Vocational Schools
The development of the information age provides a broad prospect for the application of computers, and at this time, the importance of basic computer education has gradually emerged. However, there are many problems in computer basic teaching in secondary vocational schools in China. The author analyzes the present situation of computer basic teaching in secondary vocational schools, and puts forward corresponding reform measures according to his own work experience.
Keywords: information age; Computer foundation; Current situation of teaching; reform measures
With the continuous development of society, the basic computer teaching in secondary vocational schools should not only respond to the needs of social and technological development, but also take into account the comprehensive quality of secondary vocational students.
First, the analysis of the current situation of computer basic teaching in secondary vocational schools
(A) the level of knowledge of students is very different.
Information technology courses are offered in primary schools and junior high schools in China. However, due to the lack of computers and related equipment in most rural schools, students seldom practice, which leads to unsatisfactory learning effect of computer knowledge and skills. Secondly, although schools in urban areas have the ability to provide good teaching conditions, because many students are mainly engaged in leisure and entertainment, their computer knowledge level is relatively poor; In addition, because teachers' teaching methods are rigid and accustomed to teaching theoretical knowledge in computer basic teaching activities, students' interest in learning gradually decreases. Affected by the above factors, students' knowledge level after entering secondary vocational schools is quite different, and their mastery of basic computer courses is also different.
(2) Teachers' teaching methods are single, and there is a lack of interaction between teachers and students.
In the process of computer basic teaching in secondary vocational schools, teachers often use PPT courseware and example demonstration to teach, teachers blindly instill knowledge on it, and students passively accept the knowledge taught by the following teachers. This single teaching method lacks teacher-student interaction. In the long run, students will get used to passively accepting what teachers teach, lose the ability of independent thinking, and their enthusiasm for learning will gradually weaken, eventually forming a psychology of hating basic computer courses.
Second, the reform measures of computer basic teaching in secondary vocational schools
(A) teachers should reform the teaching mode
Computer basic teaching includes not only theoretical teaching, but also computer operation teaching. Obviously, the traditional blackboard writing teaching mode can no longer meet the operation on the computer. Teachers should change the teaching mode and make full use of multimedia equipment such as computers and projectors to present the teaching content to students intuitively. This intuitive teaching method will enable students to transform abstract knowledge into concrete knowledge, thus improving the teaching effect.
(2) Schools should choose suitable teaching materials and strengthen school-based research.
At present, most of the basic computer textbooks of secondary vocational schools in China are compiled by secondary vocational schools. These textbooks have not changed much after years of use, but the development speed of information technology is very fast. Therefore, the textbooks compiled by secondary vocational schools can no longer meet the current teaching needs, and schools should choose other suitable textbooks. In this regard, schools can set up research groups according to the learning needs of students of various majors to compile school-based textbooks for students of various majors. School-based textbooks should reflect the characteristics of easy learning and practicality for students. After the school-based textbooks have been put into use for a certain period of time, the teaching and research group should make appropriate adjustments to the contents of the textbooks according to the use effect, so as to improve the quality of the school-based textbooks.
(C) teachers should appropriately adjust the teaching content
China's education has always emphasized? Teaching students in accordance with their aptitude? However, for secondary vocational school students with poor learning foundation and low learning enthusiasm, in order to achieve the purpose of teaching students in accordance with their aptitude, teachers should adjust the teaching content of computer basics and choose appropriate knowledge modules from textbooks to teach students. Among them, the knowledge modules suitable for teaching are Internet knowledge module, Word for word and chart processing, Excel for spreadsheet processing, PowerPoint for presentation, etc. The teaching content should not only consider the characteristics of students, but also consider the needs of different majors for basic computer knowledge, and strive to organically combine basic computer courses with professional applications to realize the learning purpose of basic computer knowledge serving professional disciplines.
Improve the professional level of teachers.
The society is constantly innovating, and the information technology is changing with each passing day, so the teaching of computer foundation should also change accordingly. Therefore, teachers should constantly learn new knowledge and skills, update their own knowledge system, strengthen the study of modern education and teaching theory, and improve their professional level. Of course, schools should also strive to make teachers contact and master new knowledge, new software and new technology by organizing teachers to participate in vocational training; At the same time, schools should also regularly assess teachers to examine their teaching ability. With the improvement of teachers' professional level, the quality of teaching can naturally be improved.
Third, the conclusion
Computer basic education in secondary vocational schools is an important part of vocational education in China, an important way to train computer professionals or related talents, and also the main way to improve students' computer skills in secondary vocational schools. Therefore, information technology teachers in secondary vocational schools should continue to promote the reform of computer basic teaching, solve the problems existing in computer basic teaching, and make computer basic teaching play more roles.
