Abstract
The present invention provides a data management system that efficiently uses data areas and significantly increases search efficiency. According to this invention, in the data management system coordinate data is stored in an index . An index generating means generates the index from the coordinate data. A range search means finds all coordinate data included in a specified range in the n-dimensional space, that is, one or more pieces of coordinate data which exist in an outmost area and which is included in a specified range. A nearest data search means finds coordinate data nearest to a specified coordinate data. The index contains area nests in the form of code strings representing coordinates of dimensions and sequences of terms representing divisions.
