At present, computer-aided management has been widely used in all walks of life in China, but generally speaking, the application of computers in China's management is still in its infancy. Although it has developed rapidly in the past two years, it still needs continuous exploration and research. In particular, computer-aided attendance management has only been popularized and developed in China in recent years, and has become very popular in many developed countries. All industries are actively using modern means to continuously improve service quality and work efficiency, which to a great extent poses more and more severe challenges to enterprises, and puts forward higher requirements for enterprise system in terms of administrative functions, enterprise management level and quality service. Establishing a scientific and efficient information management system is the only way to solve this problem. As a kind of management within an enterprise, so is attendance management. Due to the large number of employees, the specific actual situation of each employee is not the same. Without a complete management, the daily attendance work will be disastrous.

However, with the continuous maturity of China's market economy, the competition among enterprises is also intensifying. At the same time, the change of enterprise organization management concept and the standardization of business process are constantly improving. The development of attendance management information system is an important link to improve enterprise information management. It can not only identify employees who enter the enterprise, but also record, analyze and summarize the attendance of employees such as leave, vacation and overtime.

This design takes Microsoft Visual Studio 2005 as the development environment, uses the popular C# programming language for coding, and uses MicrosoftSQL Server 2005 as the database.

1.2 research background and significance 1.2. 1 research background

Many domestic enterprises use traditional manual methods to record the daily attendance of employees. This method is cumbersome and error-prone, with poor accuracy, transparency and real-time, which is greatly influenced by human factors and increases the human resource cost of enterprises. At the same time, the traditional manual attendance management is prone to omissions, and even the attendance supervisor may have unequal attendance due to human feelings, which causes the lucky psychology of employees and is not conducive to the personnel management of enterprises.

Nowadays, social informatization has become a trend, and the development of information technology revolution is promoting the transformation of industrial capital economy to information economy and knowledge economy. It is an urgent task for enterprises to realize enterprise informatization construction and new modern management by using modern information technology such as computer technology and communication technology. With the progress of modern science and technology, using information and computer technology to manage employee attendance has become an indispensable part of modern enterprise operation. The rapid increase in the number of employees in modern enterprises and the frequent changes of employees make the management of attendance statistics increasingly complicated, and it is difficult for the traditional enterprise attendance management method to ensure the accuracy and real-time performance of data. At the same time, with the rapid development of computer technology, the application of computers in enterprise management is gradually popularized, and it is imperative to realize the attendance management of enterprise employees by using computers.

1.2.2 Significance of the study

With the popularization of computers and the rapid development of computer science and technology, people begin to use computers more and more to solve practical problems. Attendance management is an important part of enterprise information management. Faced with a lot of commodity information, it will waste a lot of time, manpower and material resources, and the statistical data is also very troublesome. An enterprise checks the attendance of employees who go to work normally, miss work and work overtime, and outputs it in the form of reports, reasonably adjusts the work arrangement of employees, and statistically analyzes and processes the attendance data with a computer to get all kinds of statistical reports and original attendance data we need. It is convenient for enterprises to manage employees. Now enterprise managers have a good enterprise management information system, which can strengthen the management of employees and enterprises and promote the development of enterprises to a certain extent. Therefore, it is of great significance to develop an appropriate and high-quality enterprise attendance management system to manage employees' attendance. It is very important to develop an attendance management software with friendly interface and simple operation for automatic processing, which is also the purpose and significance of this system development. Through the development of this attendance management system, students' practical ability has been exercised, which is also of great significance to the cultivation of students' future study and work ability.

1.3 development at home and abroad

For a long time, many enterprises in China have used traditional manual methods to record the daily attendance of employees. This method is cumbersome and error-prone, with poor accuracy, transparency and real-time, which is greatly influenced by human factors and increases the human resource cost of enterprises. At the same time, the traditional manual attendance management is prone to omissions, and even the attendance supervisor may have unequal attendance due to human feelings, which causes the lucky psychology of employees and is not conducive to the personnel management of enterprises. ; With the arrival of the information society and the corresponding improvement of national quality, the information literacy of enterprise employees has been generally enhanced, which provides a strong personnel guarantee for enterprises to use attendance management system reasonably. From the analysis of some enterprise attendance management systems that appear now, we can roughly divide the enterprise attendance management system into two types from the management function: the first is the access control security system. The entrance guard safety management system is an effective measure to solve the entrance and exit safety management of important departments, which integrates microcomputer automatic identification technology and modern safety management means. Can automatically identify the identity of people in and out, record the time of people in and out, etc. , but generally there is no comprehensive attendance analysis function. The second is the comprehensive attendance management system. This kind of attendance management is related to the attendance record management of employees in the company. It is generally used by enterprise management departments to master and manage the employee attendance dynamics of enterprises, and generally includes two overall functions: attendance record and attendance analysis. It can not only identify the identity of employees who enter the enterprise, but also record, analyze and summarize the attendance of employees such as leave, vacation and overtime. According to the attendance rules formulated by the system, the attendance results are automatically analyzed. To sum up, the research and development of attendance management system and the introduction of enterprises need to be adapted to local conditions. The attendance management information system based on bar code has the functions of online attendance, attendance data statistics and employee information management.
