What does computer software system maintenance include

Perfection maintenance Perfection maintenance is a modification to expand functions and improve performance, which mainly refers to the addition of some functions and performance features to the existing software system that are not specified in the system analysis and design stage. These functions are very necessary to improve the system functions.

Specific work content: system installation, configuration and upgrade. Install and configure system software, hardware and related supporting facilities according to the needs of the system to ensure the normal operation of the system; resource management.Manage the resources of the server, including storage space, memory, bandwidth, etc., to ensure the efficiency and stability of the system; monitor management.

Computer maintenance is divided into two parts: hardware maintenance and software maintenance. Hardware maintenance mainly refers to the maintenance of hardware equipment such as motherboard, graphics card, processor, hard disk, monitor, etc. on the computer. Software maintenance refers to the maintenance of the system software and application software on the machine after the machine is assembled.

Computer system maintenance refers to regular inspection, repair and optimization to ensure the normal operation of the computer system. It mainly starts from hardware and software. Hardware includes the maintenance and upgrade of the main components of the computer; software includes the update and antivirus of the computer operating system.

What are the main aspects of system maintenance

What are the main aspects of system maintenance as follows: Hardware maintenance: including the installation, upgrade and maintenance of hardware equipment. This includes the maintenance and repair of servers, network equipment, computers and other hardware to ensure the normal operation of the system. Software maintenance: including the installation, update and repair of operating systems and applications.

Hardware equipment maintenance. It mainly refers to the daily maintenance and management of the mainframe and peripherals, such as the cleaning and lubrication of machine parts, the overhaul of equipment failures, the replacement of wearable parts, etc. These works should be carried out regularly by a special person to ensure the normal and effective operation of the system.

Application software maintenance Once there is a problem or change in business processing, the application and related documents should be modified. Application software maintenance is the most important part of system maintenance.

Physical security maintenance. Prevent accidental or man-made damage to physical equipment. Set up security maintenance. Prevent hackers from gaining remote control of hardware equipment. Security maintenance of the software system. The software system is easy to be destroyed by people. Install the patch. Install patches in time to solve vulnerabilities. Install and set up the firewall.

What is the maintenance knowledge of the computer software system

Maintenance of the monitor: Pay attention to protect the screen at ordinary times. If the surface of the screen is dirty, use a small amount of water-moisted degreasing cotton or lens paper to wipe. When the computer is not in use, cover the monitor with a dust cover to prevent dust from entering the interior.

Common sense of computer system maintenance: Do not play games with batteries. When the computer system maintains games, the high power brought by CPU and graphics card will seriously damage the lithium battery of the notebook.

Account and password protection can be said to be the first line of defense of the system. At present, most attacks on the system on the Internet start with intercepting or guessing the password.

Computer soft and hardWhat is the maintenance knowledge of parts? Common sense of computer software and hardware maintenance. Computer maintenance is divided into two parts: hardware maintenance and software maintenance. Hardware maintenance mainly refers to the maintenance of hardware equipment such as motherboard, graphics card, processor, hard disk and monitor on the computer.

The meaning of application software system maintenance and redevelopment

1. Application software system maintenance refers to the activities of partial modification or improvement of the developed and put into operation of the application software system. Major changes and redevelopment refers to the need to make major changes to the running system, and a new system needs to be redeveloped to replace it.

2. Software maintenance mainly refers to the partial or complete modification of the application according to changes in requirements or changes in the hardware environment. When modifying, the source program should be fully utilized.After modification, fill in the program change registration form and write the differences between the new and old programs on the program change notice.

3. Monitor the system log. By running the system log program, the system will record the use of the system by all users, including the recent login time, the account used, the activities carried out, etc. The log program will generate reports regularly. By analyzing the reports, you can know whether there are any abnormalities.

4. Software maintenance refers to a series of management and technical activities carried out to ensure the normal operation of the software system, improve performance, adapt to environmental changes and meet user needs after the software development is completed and delivered for use. Bug repair: Various errors or anomalies may occur during the operation of the software.

erp system maintenance (erp system maintainer)

1. Business process management (assist the company's business department in formulating corresponding ERP business processes, usually mainly in business process maintenance). The company's ERP documents are perfect (secondary development documents, technical support documents, etc.). Company user demand management (mainly to prepare for the upgrade and transformation of the company's ERP system).

2. Responsible for the software and hardware maintenance of ERP system; responsible for the analysis and solution of system problems.

3. Enterprise erp system installation, simply put, is what kind of operating system it is, and whether it can be smoothly upgraded or optimized to the updated operating system state in the later stage.

fourWhen the system accidentally makes an error in the commonly used processes, don't think about the problem with the system first, and pay attention to observe whether there is anything unusual about the operation or data. If it is a system defect that can be avoided through fixed operation, the operation process should be fixed and attention should be paid to repeated training.

5. Server hardware is a necessary key condition for maintaining the normal operation of the ERP system. Once there is a problem with the server hardware, it will directly lead to the inability of the system to operate. Therefore, ensuring the normal operation of the server hardware and the daily maintenance of the hardware is an important link in the maintenance of the entire ERP system.

System maintenance includes

1. System maintenance includes account set options, operation authorization, password maintenance, account maintenance, data backup and recovery.

2. The main aspects of system maintenance are as follows: hardware maintenance: including the installation, upgrade and maintenance of hardware equipment.This includes the maintenance and repair of servers, network equipment, computers and other hardware to ensure the normal operation of the system. Software maintenance: including the installation, update and repair of operating systems and applications.

3. System maintenance mainly maintains: hardware maintenance, software maintenance, data backup and recovery, system performance optimization, and security management. Hardware maintenance It includes regular cleaning and inspection of equipment to prevent dust, dirt and other pollutants from damaging the hardware.

4. System application maintenance. Application software maintenance is the most important part of system maintenance. It refers to the modification and improvement of the corresponding applications and related documents.

5. System application maintenance, application software maintenance is the most important content of system maintenance, data maintenance, database is the basic platform to support business operation, and the operating status needs to be checked regularly.Code maintenance, code maintenance refers to the expansion, addition or deletion of the original code and other maintenance work.
