The work of this article is for the design and application of a digital hospital information systems. Modern hospital information system (HIS), is patient, use of computer, information technology and network communication means, hospital patients clinic information, medical expenses and administrative information such as the collection, storage, processing, extraction, exchange and sharing of data, in order to meet the functional requirements of all authorized users, network interconnection and data exchange with the outside world information environment, software systems at the same time. This paper focuses on: Shandong University of Traditional Chinese Medicine affiliated hospital HIS system development and implementation. Project organization of the life cycle of the system using the iterative method, proceed from the the hospital overall framework Figure, C / S structure as a hospital application system architecture, Delphi development environment, SqlServer database for the background, Gigabit fiber backbone, a hundred trillion to the the the desktop network architecture, design and divided segment. Hospital database is divided into three, respectively, carrying different business needs, and then classified the design table structure. According to the business of flowcharts and accounting flowchart by UML use case diagram represent the demand of outpatient, inpatient and storeroom, and then divide the functionality of subsystems, in compliance with international design standards, the development of the software system. Author is responsible for the needs of the 12 sub-systems, design, implementation work, it can not be reproduced here, only select medical advice management subsystem case about, Draw your doctor first management subsystem use case diagram, and then details the design of the interface and module. The system uses a combination of theory and practice, the details of the adjustment and improvement through practice, in order to achieve the desired results, and is set to be applied to the actual hospital information system. The project since its five years of work in the continuing application. As an application of the contribution is (1) to achieve the the Outpatient Prescription reverse print, solve business needs; (2) attempt to use ADO instead of BDE interact with the database; (3) HIS system is mainly to achieve the business of the hospital, HIS system often query the information in the database, which requires the introduction of the crosstab technology, existing query process of modifying the original program to increase the stored procedure; (4) there is a connection between different applications , such as HIS and LIS the HIS and Medicare interface, stored procedures written by the author, the two sides have reached a seamless connection; (5) automatically by the database server backup and recovery work, both to ensure safe and convenient and feasible; (6) disaster recovery log database.
