This project, a network medical information system, is one of the good examples, that makes medical treatment services ubiquitous through the widely-spread network systems in the world. In this way, patients can register to a hospital at home through the Internet, and doctors also give medical care through the Internet. At the same time, doctors can fetch related data such as case history or medical photographs placed in remote database systems on the Internet to help making diagnoses. In other word, this is the concrete realization of a “networked hospital”. We choose the distributed object technology to implement the system. It not only increases system efficiency but also is of great help in system extensibility and maintenance. There are a few competing distributed object technologies and we choose: DCOM (Distributed Component Object Model) by Microsoft to implement the system. Although DCOM is used, we also try to make use of the advantages in other technology to maximize system performance. During the execution process of this sub-project, we studied these distributed object technologies in depth, and acquired much useful knowledge from them. After that, a simplified version of the network medical information has been implemented in the whole project. We not only acquired much experience of DCOM programming but also researched issues such as service efficienty, system reliability, extensibility, and fault tolerance mechanisms during the development of the system. It is foreseen that Internet applications will be based on distributed objects in the near future. The progress on this topic is very fast in the industry, and we have to keep pace with it in the academia. With the development of the medical information system on the Internet, we have acquired useful experiences of the implementation details using distributed object technology, and the project will build up a solid foundation on the development of other broadband network services. |
