Along with the continuous advancement of China's Internet age, China's computer science and technology is also in the process of continuous development and innovation. In the process of China's continuous development of computer technology, computer software occupies a very large part. As an important part of computer system, computer software system in the process of running can effectively realize the various functions of the computer and application, but in the process of computer operation, very prone to problems and loopholes, so we need to in the process of computer daily operation to make the necessary maintenance, only to the daily maintenance of computer software for computer development premise, can effectively improve computer application effect, enlarge the range of computer. This paper mainly elaborates and analyzes the maintenance measures of computer software. It is hoped that through the elaboration and analysis of this paper, the application effect of computer software in China can be effectively improved and the application assumption of computer software can be achieved. Meanwhile, it also contributes to the continuous development of computer technology in China.

In the process of computer operation in China, computer related software is particularly important. According to the time proportion of computer operation, the maintenance time of computer software and the overall workload of computer software maintenance can account for about 70% or more of the overall life of computer software. Therefore, in the process of computer software application, we should pay enough attention to the maintenance of computer software. In the process of computer software maintenance work, we mainly refers to the computer software for computer software that was put into application in four kinds of maintenance work, the first is the correct maintenance of computer software, the second is adapt to the maintenance of computer software, again is the perfect maintenance of computer software, the last is the preventive maintenance of computer software. In the process of performing the above four kinds of computer software maintenance work, software maintenance is as important as software development and software production, which is very complicated. Therefore, special attention should be paid to the maintenance of computer software in the process of software maintenance, and targeted maintenance should be carried out according to software problems, so as to effectively realize the maintenance effect of computer software. In the process of computer maintenance, we still have a lot of work to deal with and try, so the maintenance of computer software is still a long and arduous work, which needs our attention in the future work.

According to the above elaboration, we can know that in the process of computer software maintenance, there are mainly four ways of software maintenance. The following is a detailed elaboration and analysis.

In the process of computer software maintenance, corrective software maintenance mainly refers to software maintenance in the case of errors in the process of computer software application. According to the relevant statistics of software application, when the computer software is delivered and used, the coding errors and other problems in the computer software will often occur, accounting for about 3‰ of the overall computer software. Although this data is relatively small, but in the computer software coding set up very large, which will virtually increase the number of computer software coding, computer software applications brought a very large interference. So we are in the process of computer software maintenance, modification and maintenance according to this problem, to correct errors in the actual work mainly can be divided into 5 types, first is the calculation error of the software, followed by the software of logic errors, the third is the software coding errors, again is a software documentation errors, the software of data error, the above five kinds of computer software error in the process of practical application of high frequency, thus in the actual computer maintenance work in the process to pay due attention to the problem of this type of computer software, and in a timely manner for processing and maintenance.

In the process of computer software maintenance, adaptive software maintenance mainly refers to the targeted maintenance of the adaptability of computer software to the external environment in the application process. In computer software application in the process of the external environment change of computer software, mainly includes four kinds of external environment change, first of all is that computer related hardware upgrade changes, the second is the related operations of the computer system upgrade changes, is a computer related data upgrade changes again, the last is computer software research and development in the process of change related standards and relevant regulations. With the occurrence of the above four changes, we should specifically maintain the adaptive performance of computer software, so as to ensure that computer software can effectively adapt to the changes in the external environment of the computer in the process of application.

In the process of computer software maintenance, perfect work maintenance mainly refers to the improvement and upgrade of software performance in the process of computer software application, which can effectively improve the application performance and service life of computer software. It should be noted that in the process of maintenance of computer software perfection, the upgrades and performance improvements we made were not fully or fully reflected in the instructions carried by the software itself. This kind of computer software perfection work maintenance mainly is after the software application period, carries on the functional perfection according to the user's actual demand. In the process of this kind of maintenance work, although there is no original software manual for guidance, but in the actual work should still follow the software maintenance related guidelines and standards.

In the process of computer software maintenance, preventive work maintenance mainly refers to a maintenance work aimed at improving the performance and reliability of software that is still in normal use. The main working method of this kind of maintenance work is the actual method of software engineering. In the process of maintenance, we can redesign or upgrade some or all of the functions in the software. To improve and enrich the performance of the application through programming and performance retesting. The main purpose of doing this is for the computer software in the later stage for the maintenance of the normal development. This maintenance method is very common in the early application of computer software in China.

In the process of computer software maintenance upgrade, we have a lot of specific maintenance requirements, summarize three requirements, can be classified as the first is in the process of computer software maintenance upgrade work, we require to run the software operating system for regular check on the quality, guarantee the computer software in the process of application, keep on an application level; Secondly, in the process of software maintenance and upgrading, we should ensure that the data related to computer software in the process of maintenance and upgrading is completely correct, so that the computer software after maintenance and upgrading will not deviate from the original data model. Thirdly, in the process of computer software development and upgrading, professional operation must be carried out by professional staff, so as to effectively guarantee the integrity and reliability of computer software maintenance and upgrading.

The maintenance of computer software is almost as complex as the development process, so software maintenance activities can often be defined as the repetition of the previous phases of the software lifecycle. The general steps are: determine the modification type; Determine the need for modification; Request for modification; Demand analysis; Approve or reject a request for amendment; Scheduling tasks; Design; Design review; Code modification and error correction; Review coding modifications; Test; Update documents; Standard audit; User acceptance; Review the impact of modifications on the system after installation. In the implementation of software maintenance activities, the following matters should be noted: firstly, establish a special maintenance organization to improve the control and efficiency of maintenance, motivate maintenance personnel, and avoid lack of confidence. Second, develop a system maintenance plan, which includes replacing obsolete modules and new versions.
