Maintaining Semi-structured Spatio-Temporal Data Based on Nesting-Relation-Oriented Model

摘要：

semi-structured spatio-Temporal data has become prevalent with growth of GIS. In this paper, we propose to use Nested natural of spatio-Temporal data to storing & maintaining it efficiently in an Object-Relational Database based on Nesting-RelationOriented data Model- one of NINF database. This model not only reflects the nested structure of semi-structured spatio-Temporal data, but also distinguishes between entity object classes and Spatio- Temporal nested relationship classes, and between attributes of entity object classes and attributes of nested relationship classes using more data semantics.Our approach has a little redundancy in storage and more efficiency of update in manage.
