【摘要】：多粒度時(shí)空對(duì)象關(guān)聯(lián)關(guān)系描述現(xiàn)實(shí)世界客觀實(shí)體之間存在的各種關(guān)系及其相互影響,是對(duì)實(shí)體間關(guān)聯(lián)、作用關(guān)系的表達(dá),按照其描述主體的不同主要分為時(shí)間關(guān)聯(lián)關(guān)系、空間關(guān)聯(lián)關(guān)系、屬性關(guān)聯(lián)關(guān)系和綜合關(guān)聯(lián)關(guān)系。本文從全空間信息系統(tǒng)的背景出發(fā),對(duì)多粒度時(shí)空對(duì)象關(guān)聯(lián)關(guān)系的基本概念進(jìn)行了闡述,明確了其形式化表達(dá)方式和分類。在此基礎(chǔ)上,對(duì)關(guān)聯(lián)關(guān)系的構(gòu)建和管理進(jìn)行闡述和分析,說(shuō)明了靜態(tài)構(gòu)建方式和動(dòng)態(tài)構(gòu)建方式的適用場(chǎng)景。關(guān)聯(lián)關(guān)系通過(guò)約束作用和行為傳導(dǎo)機(jī)制來(lái)維持?jǐn)?shù)據(jù)世界的一致性和聯(lián)動(dòng),本文最后對(duì)關(guān)聯(lián)關(guān)系的約束類型及其定義和關(guān)系-行為傳導(dǎo)機(jī)制進(jìn)行了簡(jiǎn)要說(shuō)明。
[Abstract]:Multi-granularity spatio-temporal object relationships describe the relationships and their interactions among the real world's objective entities. They are the expressions of the relationships between entities and their roles. According to the different description of the main body is divided into temporal correlation, spatial correlation, attribute association and comprehensive association. This paper starts from the background of the whole spatial information system. In this paper, the basic concept of association relation of multi-granularity spatio-temporal objects is expounded, and its formal expression and classification are clarified. On the basis of this, the construction and management of association relationship are expounded and analyzed. This paper illustrates the applicable scenarios of static and dynamic construction. The relationship maintains the consistency and linkage of the data world through the mechanism of constraint and behavior transmission. At the end of this paper, the constraint type and its definition and relation-behavior transmission mechanism of association relations are briefly explained.
