Abstract
In order to extend database technology beyond traditional applications a
new paradigm called ``externalization of database functionality'' has
been proposed in research and development. Externalization of database
functionality is a radical departure from traditional thinking.
Traditionally, all data is loaded into and owned by the database, whereas
in the new paradigm data may reside outside the database in external
repositories or archives. Nevertheless, database functionality such as
query processing, optimization, physical database design, indexing and
more general replication support is provided. In this paper we explore
the applicability of our Concert approach when raster image data
from photogrammetry and cartography are used. We report on investigations
of a joint project where engineering applications such as 3D building
reconstruction and raster image mosaics are supported by database
functionality. We specifically mention advantages with respect to
tertiary storage integration and database memory mapping thus directly
supporting application specific algorithms.
