Design Of The Physical Examination Management Information System Bases On PowerBuilder And SQL Server

Hospital information system is an important branch of new and developing medical information science with the goal of realization management of dynamic data, with which the hospital management, clinical medical treatment and scientific research can be conducted through information network. The physical examination management information system, as an important part of medical treatment information management system, can help to improve the efficiency in physical examination, realize the efficient and quantified management. The application of the system may provide with an accurate, comprehensive and perfect archive files, with which the physical examination service and competitiveness will be greatly improved.Beginning with the discussion on the background and necessity of system research and development, the thesis analyzes the key engineering technologies, such as software engineering, object oriented method and so on. Based on that, it gives a detailed analysis on the system requisites, and expounds the system design, including the goal and principle of the system design, module design, rename, coding principle, and work process, etc. With elaborating the ways how the system realizes its functions, which include database building, windows realization and code compiling, the thesis is supposed to achieve its design of the physical examination management system.The system adopts software engineering method and object-oriented technology as its key know-how, use Sybase's PowerBuilder as the development kit and MS SQL Server as the database, and combines them in a friendly way. Bases on this, with a analysis of the system development tactics, the related technical route has be designed.In system design, based on the requirement analysis, the goal and principle and module of the system design have been defined as the first step, and then designs of total module design, process design, connection and data report design, risk design, and custom windows design are also carried out in sequence.In system realization, the design defines system operating environment in terms of software and hardware; sets up the related database; analyzes the detailed working process; lays down naming and coding principle and at last, carefully designs the customer windows and system operation. This article, with the background analysis of the physical examination system, sets up main content and the scope of the research; applies the software engineering life cycle method; points out the key points of the service through concrete analysis on the onstage basic service of the physical examination; establishes the overall system structure, and gives concrete description of functions of each administration module. Then it has carries out the overall system planning and the detailed design (various functions module, database, data connection and so on); discusses several key issues in the system research and development process; describes the system realization process; explains the operation of the system and at last, summarizes the system research and development and proposes some expectations in further study in this area as well.
