Measurement Management Information System Based On Windows Dna Research And Development

This thesis is based on the development of the Measure Management Information system of XAC. It is a penetrating study of the technology of Windows DNA in the course of the design and accomplishment of the system.Windows DNA(Windows Distributed Internet Application Architecture) is a framework which is used to construct component-based three-tier application system.Produced by Microsoft,it is aimed at how to develop a robust,stable and expansive,distributed network application.The thesis introduces the three-tier model which Windows DNA is based on, and compares the three-tire model with the two-tire model.It also introduces the essential technology COM/DCOM,MTS and COM+ in detail,especially COM+ technology and the COM+ service used in the system.Through the exploitation of the Measure Management Information system of XAC,the author has a good try on the practise of Windows DNA technologies.Aiming at the disadvantages which the Measure management exist,the thesis gives the capability aim and function aim of the system.Then the actual achievement methods for DNA-based is given here,including present layer,business logical layer and data service layer. This thesis emphasizes on our system's advantages in many aspects such as capability,security,adaptability,retractility and maintenance etc.At last, the work of research and development is summarized, and what we should do such as how to use .NET,Web Service technologies in the future is suggested too.
