ISO 12967-1:2009提供了对新系统的描述，规划和开发以及在一个企业内和不同医疗机构之间整合现有信息系统的指导，通过集成通用数据和业务逻辑的架构进入特定的架构层（即中间件），与个别应用程序不同，并通过服务在整个信息系统中访问

ISO 12967-1:2009 provides guidance for the description, planning and development of new systems, as well as for the integration of existing information systems, both within one enterprise and across different healthcare organizations, through an architecture integrating the common data and business logic into a specific architectural layer (i.e. the middleware), distinct from individual applications and accessible throughout the whole information system through services.
