Knowledge representation; relational model; intelligent tutor system; its 知識表示關(guān)系模式智能導(dǎo)師系統(tǒng)its
Compared with the hierarchical model, the relational model is quite complicated 與層次模型相比,關(guān)系模型相當(dāng)復(fù)雜。
Efficient object-oriented system realized by combining object-oriented model and relational model 對象模型與關(guān)系模型結(jié)合實(shí)現(xiàn)高效的對象系統(tǒng)
This is particularly useful if you d like to present your sql application programmers with a relational model of your native xml data 如果要為sql應(yīng)用程序的程序員提供本地xml數(shù)據(jù)的關(guān)系模型,那么這種功能特別有用。
In this paper, the original extended relational model has been improved by adopting mfm in the research of incomplete information database 本文將三值邏輯謂詞演算系統(tǒng)mf~m應(yīng)用在不完全信息數(shù)據(jù)庫的研究中,對原有的擴(kuò)充關(guān)系模型做了改進(jìn)。
As with a relational model, you must also specify how each column should be used in the structure, which you can do on the next page of the wizard 與使用關(guān)系模型時一樣,您也必須指定每一列在結(jié)構(gòu)中的使用方法,這將在向?qū)У南乱豁撝袌?zhí)行。
Abstract : after the features of two video data models, relational model and nf2 model are studied in the paper, a object-oriented model is pressented 文摘:分析了視頻數(shù)據(jù)的兩種數(shù)據(jù)模型(關(guān)系模型、nf2模型)的特點(diǎn)后,提出了一種面向?qū)ο竽P汀?i class="labawb" onClick="playMp3('sound_c_9')">
Object model emphasized particularly on constructing applications by objects involving data and behavior; relational model inclined to memorize the data 對象模型側(cè)重于使用包含數(shù)據(jù)和行為的對象來構(gòu)建應(yīng)用程序;關(guān)系模型則主要針對于數(shù)據(jù)的存儲。
