Examples
- Consequently , realize the uniform searching between distributed heterogeneous databases . this paper makes a brief introduction about digital library technology , distributed database technology and middleware , etc . moreover , proposes the four layers model based on corba middleware and the actual solution built with visibroker . and makes a detail analysis and realization to three key part in scheme , those are idl mapping 、 server object at server end and the procedure of calling services at client end
本文简要介绍了数字图书馆技术、分布式数据库技术以及中间件技术，并提出了基于corba中间件的四层解决模型以及利用visibroker搭建的实际解决方案，对解决方案中的三大部分- - idl映射、服务器端服务对象和客户端调用服务过程作了详细的分析与实现。 - Distributed database technology is the integration of database technology and computer network technology . apart from the characteristics of centralized database such as data logical independence and physical independence , it has its own unique characteristics such as distributed independence of data . it has to consider not only the self - government of local places , but also the logical integrity of the whole database
分布式数据库技术是数据库技术和计算机网络技术的结合，它除了具有集中式数据库所具有的特点外，还具有它自己独有的特点：它不但要考虑局部场地的自治，而且要解决全局数据库的逻辑整体性；它除了具有集中式数据库所具有的数据逻辑独立性和物理独立性，还具有数据的分布独立性。 - Firstly , this paper contrapose the disfigurements which exist in the internal gis software , the trend and technology of gis in the era of internet was discussed . secondly , using distributed computing technology to solve the problem of speed , making use of distributed database technology to settle the data distribution and share problem and utilizing distributed object technology to solve the problem of integrating the subsystems . finally , according to analysis for actual problem i have met in my developing process , this paper put forward a blue print which is very available to webgis based on distributed environment
本文首先针对目前国内gis软件的缺陷，对互联网时代地理信息系统的发展趋势和技术进行了探讨；然后提出利用分布式计算技术解决速度问题，利用分布式数据库技术解决数据分布和数据共享问题以及利用分布式对象技术克服各子系统集成问题的思路，探讨了在上述技术的基础上开发动态更新的webgis ；最后通过对实际应用中所遇到问题的分析，提出了切实可行的基于分布式环境的webgis解决方案。
