基于Windows DNA构造三层结构的GIS方案

A Three-tier Scheme of GIS Based on Windows DNA

本文论述了一个基于Windows DNA技术构造三层结构的地理信息系统的一个可行方案,该方案充分体现了Microsoft公司的COM/DCOM,COM+技术在实际工程中的运用。事实表明利用Windows DNA技术可以提高系统的性能,简化系统维护性和增强系统的可扩展性。

This paper presents a three-tier feasible scheme of GIS based on Windows DNA and the scheme fully embodies the application of technology of COM/DCOM, COM+ in practice. Facts indicate that it can improve performance, decrease the difficulty of maintenance and increase the scalability of the system by using Windows DNA technology.
