Componentized software promises easier, more fine-grained integration of disparate software systems. Variations of the technology can help to achieve tight coupling among disparate programs on the clinical workstation or across wide area networks. HL7 members have been designing extensions to the protocol for the exchange of healthcare information using Microsoft OLE and CORBA technologies. Extensive prototyping has been performed, including the simultaneous interconnection of sixteen different vendor systems exchanging demographic data and lab results. The first release of this standard will be notable in that the specifications for OLE and CORBA will be entirely isomorphic, they will be based directly, on HL7 version 2.3, and they may easily be implemented in systems that are not written using object-oriented programming tools. As HL7 version 3 is developed on an object-oriented model of healthcare information, the same approach will be used so information about the objects may be shared using CORBA and OLE.
组件化软件有望实现不同软件系统更轻松、更细粒度的集成。该技术的变体有助于在临床工作站上或跨广域网的不同程序之间实现紧密耦合。HL7成员一直在使用Microsoft OLE和CORBA技术设计医疗保健信息交换协议的扩展。已经进行了广泛的原型设计，包括同时互连十六个不同供应商系统，以交换人口统计数据和实验室结果。该标准的首个版本将值得注意，因为OLE和CORBA的规范将完全同构，它们将直接基于HL7版本2.3，并且可以很容易地在未使用面向对象编程工具编写的系统中实现。由于HL7第3版是在医疗保健信息的面向对象模型上开发的，因此将使用相同的方法，以便可以使用CORBA和OLE共享有关对象的信息。
