This paper attempts to introduce a spatio - temporal data model for socio - economic statistics and implement it in esri geodatabase . according to the principle of information system analysis and design and the modeling method of spatio - temporal data , this paper introduces gis and spatio - temporal data model to statistical data management 研究的技术线路为:统计数据需求分析、收集整理;统计数据的时间、空间等特征分析;时空数据模型的探讨与设计;物理数据模型的设计;统计数据库的开发与应用。
( 3 ) for the contents are so complicated , and system is very magnificent , we emphasised expound the system analysis and design of mgis extensively and deeply from data - type , content , structure and characteristic that involving almost all geoscience ; analyse all treatment course of datum in mgis with dataflow chat ; carry on data - library design . collectivity structure design , interface design , software and hardware design ; organize scheme of source and process ; flow , and overall make geophysics - data - analysis - subsystem for example to display system framework of mgis ( 3 )由于mgis内容复杂、系统庞大,本文只进行了mgis的系统分析和设计,从数据类型、内容、结构和特点对多源地学数据做了最广泛和深入的论述,内容涉及所有地学学科;用结构化分析方法分析了各学科数据在mgis中的处理过程;进行了系统的数据库设计、总体结构设计、界面设计和软硬件设计;提出了mgis的数据组织方案、综合处理流程和系统构架图;以地球物理数据分析子系统为例来说明mgis各个子系统的大致面貌。
The architecture of grid file system services specification spells out the hierarchical structure to facilitate federation and sharing of virtualized data from file systems in the grid environment by providing the virtual namespace that will allow association of access control mechanisms and metadata of the underlying physical data sources Architecture of grid file system services规范通过提供虚拟命名空间来制订层次结构(这样可以在访问控制机制和底层物理数据源的元数据之间建立关联) ,从而促进网格环境中文件系统中虚拟数据的联邦和共享。
A data source in microsoft sql server 2005 analysis services ssas represents a connection to a data source and contains the connection string that defines how analysis services connects to a physical data store using a managed microsoft . net framework or native ole db provider 在microsoft sql server 2005 analysis services ( ssas )中,数据源表示到数据源的连接,并包含定义analysis services如何使用托管microsoft . net framework或本机ole db访问接口连接到物理数据存储区的连接字符串。
