语义数据模型 meaning in English
semantic data model
Examples
- We summarize the barriers of protocols , functions , data structure and semantic . in turn analyse the key contents of interoperability - attribute and semantic interoperability , and outline method of attribute representation , semantic data model and the framework of interoperability
归纳了互操作需要解决的协议、功能、数据结构和内容上的障碍；对互操作中的核心问题做了深入剖析，给出了属性的表示方法、语义数据模型和互操作框架。 - Figures describing the functional activity are named as activity figures . the activities are shown by cases , and affairs dealt with by the system are shown by arrows . idef modeling method , a model technique for semantic data , is used to describing the relation between information and forming cims information model
描述功能活动的图形称为活动图形，盒子表示活动，箭头表示由系统处理的事件； idef _ 1建模方法是一种语义数据模型化技术，用以描述信息关系，建立cims信息模型。 - The paper puts forward a kind of unifed multi - media object semantic data model ( umosdm ) based on analyzing multi - media information characteristics for setting up the model to multi - media information effectively . the model combines object - oriented data model with semantic data model and conceptual model together , and leads some concepts of artificial intelligence for the expression of the feilcl knowledge
本文在分析多媒体信息特点的基础上，为有效的对多媒体信息建模，提出了一种统一的多媒体对象语义模型( umosdm ) ，该模型将面向对象的数据模型与语义数据模型和概念模型相结合，引入了人工智能中的一些概念，以支持领域知识的表达。 - In addition , the paper designs a bottom database model , selects a multi - aim strategy combining files with known data , and establishes dual interaction data model that has explicit conceptual structure and directly aims to geographic objects , and provides backing up enquiry language ( g - sql ) . simultaneously , after analyzing and studying methods available for the under pipelines , the paper constructs survey adjustment calculation model , and according to the model , checks the survey of under pipelines . the results indicate that the model is suitable to actual requirement because it greatly increase calculation speed , meeting calculation accuracy requirement
在此基础上，对系统的底层数据模型进行设计，选择了文件与成熟数据库相结合的混合策略，并兼顾面向对象的数据库( oodb )和可扩充数据库( edb )的特点，建立了一个概念层次清晰、面向地理对象实体的双层语义数据模型以及支持模型的查询语言g - sql ，同时对地下管线的各种测试方法进行分析研究，建立了地下管线测量平差计算模型，并以此对所勘测的地下管线进行核算，计算结果表明，计算模型不仅大大提高了核算的速度，同时在计算精度上也符合核算的要求，是符合实际要求的关于测量平差计算的模型。
