Three-Dimensional Spatial Data Types

Database management system have significantly changed in the last several years from a system dealing with management of administrative data they have involved to a spatial DBMS providing spatial data types, spatial indexing and extended spatial functionality. Spatial database system as database system that offers spatial data types in its model and query language and supports spatial applications. Spatial database is mainly deal with 2-D dimensionaldata (geometric data). This is sufficient for many spatial application. But on the other hand our world is 3-D and a number of possible application can be identified that would be a greatly benefit from a treatment of 3-D data. Although the provided functionality is limited to the second dimension, various options exist for management of three-dimensional data. The idea of this topics (Research paper) is 3-D geometric information of spatial database. Our research has led so far to a called abstract model  that identifies the essential 3-D spatial data-types. &nbsp
