In the beginnings of data processing, these clusters were virtual materializations of the file cabinet contents they were replacing. Many of the solutions to the clustering of the data are embedded in the types of DBMSs that have been developed.doi:10.1016/B978-0-12-385126-0.00013-9Charles D. Tupper
3D Geo-DBMS3D spatial indexingIn the next few years, 3D data is expected to be an intrinsic part of geospatial data. However, issues on 3D spatial data management are still in the research stage. One of the issues is performance deterioration during 3D data retrieval. Thus, a practical 3D...
