Dynamic segmentation is viewed as one of the most important functions of geographic information systems for transportation applications. Although the road network and associated events (e.g., pavement material, traffic volume, incidents) can be referenced to both space and time, the spatial and temporal dimensions have not been well integrated. Modeling space-varying, time-varying, and space-time-varying events in dynamic segmentation by using an object database approach that is in line with the Object Database Management Group standard is explored. A mechanism called parametric polymorphism is used to lift conventional data types to spatial, temporal, and spatiotemporal types for maintaining knowledge about events that could change spatially, temporally, and spatiotemporally along linear features. An associated object query language, DS-OQL, was designed to support the formulation of spatial, temporal, and spatiotemporal queries on the road and event information.

The Difference

px; "> <Reflection wave by objects (things) that affected phases changing from wave and influenced thepower of wave signal. The difference kind of things will give different reflection coefficient. Wavesignal that’s happen is depends on the kind of the thing. There are three nature of the object that’scontinuing, absorb and reflecting the wave signal. Reflected coefficient with negative value that’smeans the object could reflecting the signal and the positive value means the object could absorb orcontinuing the wave signal.Reflection coefficient data could be saved in a database that its data from kinds of thing in tableform could be access anytime its needed, so we can easily to find out the value of reflection coefficient.Process of data relation in database system used SQL as programming language. Keywords: Reflection coefficient, kinds of object, database system, SQL.
