At the same time, it can give the medical cost data, so as to make use of the medical information effectively and scientifically, and improve the level of management and service. The Hospital Management System provides detail information about the patients. It includes the register of patients, the settlement of accounts, the transfer of the patients, the statistics of the admitted to hospital and discharged from hospital, the inquiries of the patients and their prescriptions and etc. The development of the system to use B / S structure, in accordance with the strict idea of software engineering to design. With the use of PowerBuilder technology and SQL Server database as the advanced technology, to realize Hospital Inpatient Department Management System. These advanced ideas and technical means ensure that the new management system can work safely and efficiently to manage the actual Hospital Inpatient Department This paper introduces the development process of the system analysis, the general design and the details of the Hospital Inpatient Department Management System after the user demand analysis of the management system. This article designs the function satisfies the hospital medical supply store management the physical demand, enables the hospital the medical supply store management to be under the scientific management, reduced the character transport charges source unreasonable consumption, finally has realized the enhancement working efficiency goal.
