Maintenance of tourism information management system includes

The maintenance of tourism information management system includes correctness maintenance, adaptability maintenance, perfection maintenance and preventive maintenance.

1. Correctness maintenance

refers to correcting errors that have occurred during the system development phase but have not yet been discovered during the system testing phase. According to statistics, the maintenance workload in this area accounts for 17% to 21% of the entire maintenance workload.

2. Adaptive maintenance

refers to the modification of application software to adapt to changes in information technology and management needs. The maintenance workload in this area accounts for 18% to 25% of the entire maintenance workload.

3. Perfection maintenance

This is a modification to expand functions and improve performance. It mainly refers to adding some functions and performance features to the existing software system that were not specified in the system analysis and design stages. These functions are very necessary to improve the system functions. Also included are improvements to processing efficiency and writing procedures.

This aspect of maintenance accounts for 50% to 66% of the entire maintenance work, which is a large proportion and is also an important aspect related to the quality of system development. In addition to completing maintenance in this area in a planned and step-by-step manner, attention should also be paid to adding relevant documentation to the previous corresponding documents.

4. Preventive maintenance

In order to improve the reliability and maintainability of application software, and to adapt to future changes in the software and hardware environment, proactively add new preventive functions, In order to enable the application system to adapt to various changes without being eliminated. The maintenance workload in this area accounts for about 4% of the entire maintenance workload.

Essentials for building a tourism management system:

1. System management objectives

No matter what type of tourism management system it is, the system must first be clearly defined when building it The overall goal of management, and then decompose the overall goal of the system through goal orientation to form the sub-goals of each subsystem, and then use scientific management methods to encourage each subsystem to work hard to achieve the established goals, thereby completing the overall management goals of the tourism management system .

2. System management resources

Once the system management goals are determined, various management of people, finances, materials, etc. must be organized based on the requirements for goal realization and the actual needs of each subsystem. resources, so that the distribution of various resources in each subsystem reaches a reasonable ratio, so as to maximize the input-output ratio of resources. The tourism management system can efficiently achieve management goals and complete management tasks only with the guarantee of reasonable management resource organization.

3. System management control

The tourism management system is a man-made system. Only with system control links can we ensure that the work of each subsystem develops in a coordinated manner toward the goal.

The so-called system management control refers to the premise of information feedback from the tourism management system and the adoption of different control methods to monitor the operation process of each subsystem of tourism management based on the different functions and management objectives of each subsystem. , to ensure the normal operation of the tourism management system.
