多粒度时空对象关联关系基本问题初探

多粒度时空对象关联关系描述现实世界客观实体之间存在的各种关系及其相互影响,是对实体间关联、作用关系的表达,按照其描述主体的不同主要分为时间关联关系、空间关联关系、属性关联关系和综合关联关系。本文从全空间信息系统的背景出发,对多粒度时空对象关联关系的基本概念进行了阐述,明确了其形式化表达方式和分类。在此基础上,对关联关系的构建和管理进行阐述和分析,说明了静态构建方式和动态构建方式的适用场景。关联关系通过约束作用和行为传导机制来维持数据世界的一致性和联动,本文最后对关联关系的约束类型及其定义和关系-行为传导机制进行了简要说明。

The Basic Issues of Associative Relationship of Spatial-temporal Objects of Multi-granularity

The associative relation of spatial-temporal objects of multi-granularity describes the relations and mutual effects among objective entities in real world. It is the expression of entity relationship and mutual effects. According to its different describing subject, the associative relation can be divided into temporal relation, spatial relation, attribute relation and comprehensive relation. This paper begins with the background of pan-spatial information system, elaborates the basic conception of the associative relation of spatial-temporal objects of multi-granularity , and defines its formalized expression and classification. We also illustrate and analyze the construction and administration of associative relation, the applicative scene of static construction method and dynamic construction method. The associative relation maintains the consistency and linkage of the digital world through constraining effects and behavior conduction. Thus, this paper gives a brief illustration of constraining types and definition of associative relation and relation-behavior conduction mechanism.
