Recommendations: When you accidentally do not like to install the software, not smart aleck of the hard disk you can see the deletion of the software program, which may cause system "registry" error, thereby affecting the stability of the system, there are some software installation process of anti-Uninsatll not write well, can not be restored after deletion of the original features of the system, it would lead to "the procedure is invalid, close the program" or "reinstall" and other errors; there most of the procedures after the removal of 12 would leave the garbage DLL file, which not only caused by the mast system, but also indirectly affect the system's operating efficiency, the best way is twofold: First, the software is used to find the ask a friend first, and then installed it again; Second, the request of various expert advice online.

建议：当您不小心安装了不喜欢的软件之后，不要自作聪明的把硬盘中你所能看得到的软件程序删除，这可能会造成系统"登录"错误，进而影响系统的稳定性，也有某些软件的反安装程序Uninsatll写得并不好，删除后也不能恢复系统本来的面目，反而会出现"程序执行无效，请关闭程序"或"请重新安装"等错误；还有大部份的程序在删除后也都会留下一二个 DLL 的垃圾程序文件，这不仅造成系统的肥大，还会间接影响系统的运行效率，最好的方法有二：其一，是找用过这套软件的朋友先问一问，然后再去装它；其二，上网请求各路高手指点。

It describes mainly the process of systemdesign, including whole design, detail design, database design , security design, data structure and data code scheme, It introduces in detail how to create a graphic file of pipeline data on the MicroStation platform, and the exchange of data between the MicroStation and other GIS application software, At the same time, it introduces how to realize popular manage mode of GIS data on the MicroStation GeoGraphics, namely integratinggraphics and attribute.
