In order to handle data efficiently in new applications of database such as CAD(Computer Aided Design) and geographic information system, database management system(DBMS) needs the access method which is able to retrieve data items quickly according to a spatial relation between them. The existing spatial access methods which are based on a relation between areas containing spatial objects, they are covered or overlapped each other, is proper to retrieval of data items by the relation of region. However, the access to spatial object by other spatial relations such as distance or direction cannot be supported by previous methods sufficiently and naturally. In this paper, we suggest an efficient spatial access method named MMBT-S which is able to support retrieval by the relation not only of region but also of distance and direction. Since it is based on the set of coordinates of which spatial objects consist, MMBT-S is able to support various complex spatial accesses. Also, it can handle multi-dimensional space easily, and be applied to a heterogeneous multi-dimension such as time-space dimension.
