The input method of multi-scale data and three levels data index are investigated, a new own idea about how to represent multi-scale seamless data is advanced. The viewpoints that seamless GIS is looked on surface of globe reference ellipsoid as spatial information positioning standard and looked on geographic coordinates as reference of spatial data storage are explored, and based on reference ellipsoid surface coordinate, the measurement model of distance, azimuth angle and area are given.(4) The flowchart of data production of seamless GIS is analyzed, on the basis of the program algorithm and the interactive processing of feature adjoining relation, the data production method of seamless GIS is discussed.

研究了无缝GIS多格式、多比例尺空间数据入库的模式，创新性地提出了用数据中间件模式解决GIS多源空间数据无缝集成的新方法，研究了多比例尺数据入库的方法和三级索引机制，并对无缝GIS数据的多尺度表示提出了自己的看法；阐述了无缝GIS以地球椭球面为空间信息定位的参考面、以地理坐标进行空间数据存储的观点，并给出了在椭球坐标系下的距离、方位角和面积度量模型。

After finishing holistic analyses, and considering the specific and relative research on database technique"s application in the remote structural collaborative experiment, this thesis explores and discusses that the proposed database organization scheme can promote the efficiency of the data"s reposting in the Remote Structural Collaborative Experiment, the efficiency of the remote data exchange, and puts out the improving design compared with the NCREE system, that is to use middleware to realize the separation of the experimental process and DBMS and to set up buffer pool to solve the problems, such as to solve network replacement by getting back the experiment.

在完成了整体分析设计之后，针对数据库技术在远程结构协同实验中的应用作了具体的相关研究，探讨了本文提出的数据库组织方案在远程协同实验中可以提高数据入库效率以及远程数据交换效率以及对比NCREE系统设计提出了改进的设计思想，即采用中间件以实现试验进程与DBMS分离以及设立缓冲池以解决网络复位而要恢复试验等问题，并且还研究了在协同实验中分析中的常用数值积分算法，并着重探讨分析了算子分裂算法。

Message software can carry out the retractility and expansionary of the distributed system easily.

消息中间件可以很容易的实现分布式系统的伸缩性和扩张性。

So, we basically are we write similar word among, of course the function is very simple.

More and more practical data in sensor network、communication、Internet flow analysis and Web log etc, are transported from teledata sources. Therefore, we need to construct the middleware of distributed query processing for data streams to support above application.P2P technique is used to build a huge distributed network for the processing of large number of information by internet terminals.

现有的数据流的研究主要为集中式的流数据系统，而数据流的本质是分布式的，越来越多如传感器网络、数据通讯、Internet流量分析和Web日志等的大量数据都来自不同的远程数据源，因此，需要构建分布式数据流查询处理的中间件以支持上述各种应用。P2P技术利用互联网的终端机来建立一个庞大的分布式计算网络，并对迅速涌出的大量信息进行处理。

At last, we make a deep analysis on the combination between RFID technology and current communication systems or even communication systems to-be.
