Guest Room Comprehensive Information Management System

With the rapid development of market economy and the improvement of people's living standards, gaestgiveriet hotel industry is becoming more and more competitive, information system is an important means to improve the level of management and service. This paper follows the idea and method of software engineering to design guest room information management system. Firstly, use the data flow graph technology to carry on the demand analysis, describe the system work process; then, use the tree structure diagram to express the system function, and describe the function module; finally, design by "presentation layer Application, layer Business, logic layer Data, access layer and Data persistence layer Data" and other 5 layers of software architecture. The research content of this paper solve the key technical problems of software development, is the basis for the development and implementation of the system. Introduction With the development of information technology, especially the development of database, computer technology has entered into every field of social life and plays a more and more important role. Especially in information management, it has the advantages of convenient, high reliability, large storage capacity, good confidentiality, long life, low cost rather then incomparable advantages of manual management and so on. With the rapid development of market economy and the improvement of people's living standards, gaestgiveriet hotel industry is becoming more and more competitive. Traditional manual management or semi-automated computer management, data redundancy is high, can't be shared, can't achieve financial business data integration, can't provide customers with a full range of information services. For the gaestgiveriet hotel industry, in order to obtain the advantage in the competition, we must improve the service management consciousness in terms of management, product service and so on. Service quality is the key factor to attract customers and increase economic benefit. How to use advanced management means to improve the management level of the guest room is an important issue for every hotel manager. More and more gaestgiveriet hotel use management information system to manage the daily work, reasonable allocate of resources, improve the management level, so as to gain the advantage in the market competition [1,2]. Software design is the basis of system development, this paper is based on the comprehensive system research data, follow by the idea and method of software engineering, use data flow diagram, structure diagram and other tools to design, develop a comprehensive information system to provide technical support. Requirement Analysis of System Requirement analysis describes the purpose, scope, definition, and function of the new system when builds a new or changing existing software system. Requirement analysis is a key process in software engineering, system analyst and the software engineer determine the user's needs. Only after determine the user needs, be able to analyze and seek solutions to the new system. The main task of the requirement analysis phase is to determine the function of the software system. The most common tool for requirement analysis is data flow graph. Data flow graph is a graphical technique, which describes the transformation of information flow and data from input to output. Data flow graph is the logical model of the system, and there are no International Conference on Management Science, Education Technology, Arts, Social Science and Economics (MSETASSE 2015) © 2015. The authors Published by Atlantis Press 1039 physical elements in the graph, only describes the flow and processing of information in the system. Because the data flow diagram is a graphical representation of the logic system, even if it is not a professional computer technology personnel, it is an excellent communication tool[3,4].The analyst describes the understanding of the existing system or the idea of the target system with data flow diagrams, for the relevant personnel review and confirm. The data flow diagram of the guest room comprehensive information management system is shown in Fig. 1. According to the data flow diagram show in Fig. 1, a brief description of the process of the system is as follows: the system's users include system administrator, front desk clerk and customer. Customers can be registered in the online remote booking, can also be directly to the front desk for booking. For booking customers, forward to provide information, the reception room information, according to the room information and reservation request to the customer to arrange booking room, and ensure that the room can be delivered to customers on time, customers in accordance with the booking time to stay. Without an appointment of the customer, forward to provide real and effective information to apply for admission, the front desk through the system to check the room information, in line with the customer needs of the room, for customers to check in. When Customers during their stay, the system automatically updates the consumption amount, when the payment isn't enough to pay for the next time period, the system will send fee reminders, alert by the waiter inform customer renewals. When customers leave, customers go to the front desk, and provide the corresponding occupancy information, the reception of customers in the number of days, as well as the identity verification, through the settlement module to check the amount of customers paid, and in accordance with the relevant rules for customers to pay a fee, according to the need to issue payment vouchers and invoices, the system automatically updates customer information and hotel day income information for query statistics. System administrator complete the basic information of the system maintenance and related settings. Function Design of System Effectiveness and function The function of the software is the effectiveness and the function of the software, and the software object must be expressed and realized through the function of the software, software function is also a direct result of the software that present to the user. Users through the function of the software to understand, use and evaluation of the system, through the use of software to complete business functions. Function design is the most important content of software design. Functional design is based on the goal of the software, formed the functional model of the software to describe the results, and quantitative or qualitative describe of the functional requirements of the software. Functional design usually use modular system architecture. Modules are units that can be combined, decomposed and replaced. Modular is a way of dealing Fig. 1.
