In this task , you will learn to use the entity data model wizard to generate a set of 1 : 1 entity - to - table mapping files for the school model 在本任务中,你将学习使用实体数据模型向导来为学校模型生成实体与表一一对应的映射文件。
The objective of physical design stage is to specify the physical data and process design , using the language and features of the chosen physical environment and incorporating installation standards 实体设计推行阶段的目的,是利用所选定的实际环境的程式编制语言和特点,以及辑纳安装标准,来认定实体数据及程序的设计。
Whether the data model in stl files is correct can effect the realization of the following process . the transformation and the process of the cad data model is introduced in this paper . the criteria to evaluate the validity of stl data model and the 本文对cad实体数据模型的转换与处理作了介绍,对stl数据模型的正确性及缺陷类型作了详尽的分析,并列举了几种典型的缺陷类型;提出了一种对stl数据模型进行自动诊断的方法。
Considering actual requirement of car body modeling , further development bases on ug has been done in the paper . a surface smoothing module has been designed to make car body surface smoother , and developed another module to read part ' s data in ug database and realize data transmitting . this system can effectively support both earlier concept design and detailed design simultaneously . lt is highly interactive and flexible , and satisfies the integration of virtual design and virtual assembly . the paper expatiates a highly interactive and flexible car body modeling method and describes modeling steps in detail 根据汽车虚拟造型的实际需要,在ug平台上进行了二次开发,设计开发了车身表面光顺处理模块,使车身表面具有更好的光顺效果,同时开发了数据传输模块,读取ug数据库中的实体数据,实现ug数据库中数据与外界的交互传输。该系统能有效地支持车身的概念设计和详细设计,具有很好的交互性、灵活性,并实现车身虚拟设计和虚拟装配的一体化。
Contrasting with npsnet mechanism for single level interest management , singhal mechanism for multi - level interest management can increase the number of transmitted package while decreasing the number of receiving package . a new network communication implementing mechanism etlim ( enhanced two level interest management ) is presented for multi - level interest management 分级兴趣管理机制singhal与单级兴趣管理机制npsnet相比,能大大减少数据接收量,但会增加实体数据的发送量,为此本文提出了一种新的分级兴趣管理机制? ?两级增强兴趣管理机制( enhancedtwolevelinterestmanagement , etlim ) 。
