The database Server choose Microsoft SQL Server 2021 database, it can handle large data, while maintaining the integrity of the data and provide many senior management functions. Its flexibility, security and usability for database programming provides good conditions. Therefore, the system of software development platform is mature feasible. The hardware design, technology rapid development today, hardware update faster and faster, capacity is more and more big, the reliability more and more high, price lower, the hardware platform can be fully met the needs of the system. To sum up, this system development goal has been clear, in the technical and economic aspects are feasible, and has good benefits. Therefore system development is pletely feasible. The famous American professor Morris. Collen in 1988 was written civil of hospital information system (HIS) under the following definition: use electronic puters and telemunication equipment for hospital departments to provide the patient with medical information and administrative management information collection, storage, processing, extraction and data medical exchange ability and satisfy all authorized users of functional requirements. Development of hospital management information system (HIS) goal is based on hospital practical, focus on the court for future development, with aggrandizement hospital management, improve the quality of medical treatment, medical treatment and inquiries, convenient patients raise hospital service efficiency and quality of service, design of an accord with national function specification requirements, safety and stability, simple operation of hospital information system, for the hospital provides a prehensive range of solutions. And according to the ministry of health is formulated to the hospital information system (HIS) software basic function code of hospital information system of the article defined as the hospital information system (HIS) refers to the application of electronic puter and work munication equipment, for hospitals and its subordinate departments to provide the patient with medical information, financial accounting information analysis and administrative management information and decision analysis statistical information collection, storage, processing, extract and data munication ability, and can meet all authorized users for information of various functional requirements of puter application software systems. As a general hospital information management system has the following features: Practicality. 1. Practicality is certain system needs and select technology first principles. Hospital information system construction is a process of constant development, and software technology in fast development. First need to target positioning in a reasonable requirement of basis, should be able to meet future 3 ~ 5 years of applications. Secondly to make good use of the technical means to solve problems in use. To solve problems of level should be embodied in rational utilization technology level, the use of resource level, not only in the advanced work technology can manifest system construction of advanced level. Universality 2. Although hospitals have different anizations and the management pattern, but system can adapt to a variety of circumstances. System in the design, will make full use of the puter can realize scientific management mode and the rational flow of information to design the system to ensure that the system can meet various needs. And outpatient service medical treatment as a hospital information system construction is part of the hospital management, the appearance of the large flow, the procedure is numerous lock, in manual mode, medical personnel to do a lot of unnecessary duplication, low efficiency and accuracy is bad, not easy management, affects the work efficiency, which caused a lot of hospital patients not reasonable and effective quick medical service, even influence the quality of medical treatment, therefore, more and more hospital quicken the informatization construction pace, in order to improve the service efficiency and quality, establish a good image of the hospital, make the outpatient service work can be disciplined operation and improve the economic benefit of hospital and promote hospital development.
