The design of hotel management information system is to carry out function design, database design and application design on the basis of clear system objectives. This paper mainly discusses system design objective analysis and system function design. The system objectives are gradually defined after the investigation and study of user demand analysis and possibility analysis. User demand analysis is the key to determine the design objectives of hotel management information system and determine the success or failure of hotel management information system. Each hotel has different scales and different business directions. There are obvious differences in the requirements for the design objectives of the store management system. For example, a large hotel has rooms, restaurants, recreation, meetings and shopping centers, so it is required that the hotel management information system has complete functions and can handle all kinds of affairs such as rooms, restaurants and meetings, while a large hotel only requires the hotel management information system to manage rooms and finances. In addition, the organizations of different hotels are the same. The system structure of the hotel management information system for its use should adapt to its organizational structure. Therefore, when designing the hotel management information system, the opinions of the top, middle and bottom managers of the hotel should be carefully solicited and discussed repeatedly to make the system design objectives meet the actual needs of specific stores.
The system design objectives obtained through user demand analysis, It must be further clarified through feasibility analysis, which studies the influence of manpower, capital, technology, data acquisition and other aspects on the possibility of realizing the system design objectives, and adjusts the system design objectives. For example, it examines the requirements of the design scale of the hotel management information system on the cost and whether the hotel's economic strength can bear it; Whether the design goal can be achieved technically and which functional modules can not be achieved technically; Whether the operating cost of the hotel management information system is reasonable or not, and whether it can improve the management efficiency of the hotel, etc. On the basis of feasibility analysis, the design objectives of the hotel management information system are revised and optimized. The functional design of the system is mainly to decompose the system design objectives and divide them into several modules, each of which can achieve certain functions [2]. It is a convenient and effective method to divide the modules according to the organization of the hotel. Each module deals with the affairs of a certain department or a post in a department of a hotel. Based on this principle, we set up a general module structure of star-rated hotel management information system, as shown in Figure 1. The functions of the main subsystems are introduced as follows. The reservation subsystem: individual, group and conference reservation registration. In order to make reservations for rooms, restaurants, recreation, conference rooms, etc., the pre-subsystem should be able to query rooms, restaurants, recreation and other subsystems. Understand the occupied idle state of guest rooms, restaurants and recreational facilities in a specific period of time in the future.
Reception subsystem: check-in registration management for individual guests and groups. Set up items such as guest's name, gender, place of origin, work unit, occupation, reason for staying in the hotel, check-in date, scheduled departure date, room number, room change record, etc. Accounting subsystem: provide individual consumption check-out and one-time check-out check-out for individual guests and groups, with reservation. Can inquire about the guest's account and notify the guest in case of default, etc. When checking out, you can print official receipts and detailed account sheets.
Inquiry subsystem: provide hotel service guide for guests to inquire about the hotel's traffic location, hotel exterior, hotel floor plan, hotel interior rooms, restaurants, KTV private rooms, conference rooms, etc. You can even check the lighting effect of each table, color photos of various dishes, etc.
Guest room subsystem: it provides the management of the occupied or idle state of the room, the type and state of the room items, the names of the guests, the messages left by the guests, etc.
Catering subsystem: it provides the management of ordering, taking wine, accounting or checkout for each table.
Recreation subsystem: KTV rooms, for example, Provide the management of song ordering, music playing, accounting or checkout, etc.
Telephone subsystem: it can be connected with program-controlled exchange. Provide the management of automatic telephone billing, automatic charging to guest account or checkout, printing positive telephone bill receipt, etc.
Personnel and salary subsystem: provide the management of employee's name, gender, age, education, position, attendance, work performance, salary, etc.
Financial subsystem: set up first-level and second-level detailed accounts according to the accounting system, summarize and enter the accounts, and issue general ledger and various detailed account books.
generate various financial statements.
Warehouse subsystem: used for inventory management, which can manage the daily quantity and amount of goods in and out, and at the same time, automatically control the inventory quantity and amount of goods. It can also display or print various accounts and statistical reports as required. See Figure 3.
The general manager query subsystem: it provides query and statistical analysis on customers, operating conditions, internal management and other aspects, such as the annual composition of guests, the composition of hotel income, the allocation ratio of hotel employees and rooms, etc.
3 The operation and maintenance of the hotel management information system
According to the design of the hotel management information system, By configuring the corresponding hardware and software and developing specific modules, a hotel management information system can be established. To use the hotel management information system correctly and give full play to its role, the following problems need to be solved. < P > 3.1 Fully understand the role of the hotel management information system. At the beginning of the operation of the hotel management information system, many operators, especially some managers, felt that the old recording method was more direct and skilled. Reluctant to accept new methods. This is extremely harmful to actively and enthusiastically using the hotel management information system and giving full play to its role. Hotel employees should fully and flexibly use the various functions provided by the hotel management information system for hotel management activities. Although the hotel management information system provides strong functions for middle and lower managers, the functions for senior managers are weak. However, it cannot be considered that it is not beneficial to the decision-making and management activities of senior managers. Managers at all levels in hotels should actively use the hotel management information system. < P > 3.2 Do a good job in the operation training of the hotel management information system < P > The hotel management information system involves many departments in the hotel and the level of users is uneven. Therefore, it is necessary to carry out the operation training of the hotel management information system among hotel employees. We should start with basic computer knowledge. Make hotel staff master the knowledge and basic operation of CPU, display screen, keyboard, hard disk, CD-ROM drive, multimedia, etc. On this basis, understand the functional structure and hardware configuration of hotel management information system. Finally, focus on mastering the functions and operation methods of subsystems to be used in their posts. After short-term training and trial operation for a period of time, hotel managers at all levels can skillfully operate hotel management information system. Pre-job training should pay attention to training a group of backbones. Check regularly after taking up the post. < P > 3.3 Strengthen the security control of the hotel management information system. In the hotel organization, managers at different levels and departments have different functions and powers, and they are responsible for the management business of different levels and departments of the hotel. Similarly, different users are set different access rights in the hotel management information system. No user is allowed to exceed his authority. The manager of a specific post can use the subsystem of this post to carry out the management activities within the responsibility scope of this post. For example, the reservation subsystem can check the room price of the guest room subsystem, but it has no right to change the room price. < P > 3.4 Pay attention to the maintenance of the hotel management information system, mainly in troubleshooting, function expansion, performance improvement, etc. Hotels should be equipped with full-time computer engineers who are responsible for troubleshooting. Including hardware maintenance and software error correction. With the expansion of hotel scale and diversified operation, the hotel management information system also needs corresponding function expansion, such as adding meeting subsystem, etc. Reforming the hardware and software of the existing hotel management information system to improve its performance belongs to the maintenance of performance improvement. In addition, we must pay attention to the maintenance of adaptability. For example, after the promulgation of the new accounting system, we must update the original financial subsystem and set up new financial accounts according to the new accounting system.
