[postgis-devel] [Fwd: [OSGeo-Discuss] Rasdaman array DBMS released under free license]

Mon May 11 06:34:20 PDT 2009

Hi,

Perhaps, it's something interesting and related to WKT Raster.

Pierre, is it related to WKT Raster in any way?
I've noticed the coincidence of institution - Université Laval

----------

We are happy to announce availability of the free version of the

         rasdaman ("raster data manager")

array DBMS, jointly developed by Jacobs University Bremen and rasdaman
GmbH, for download at www.rasdaman.org.

Array DBMSs extend the collection types supported by DBMSs with the
array abstraction as first-class citizen. As such, rasdaman offers a
conceptual model based on multi-dimensional arrays of unlimited size
over atomic and composite base ("cell") types. The rasdaman array
algebra serves to describe data model, query semantics and processing,
storage mapping, and optimization.

A declarative, safe query language allows flexible retrieval in the
style of SQL. ODMG-conformant C++ and Java APIs give programmatic client
access. In the multi-parallel server, arrays are partitioned
transparently into "tiles", i.e. sub-arrays, as units of storage. Each
tile goes into a relational BLOB, optionally compressed. Tile size and
shape can be chosen arbitrarily during object creation, and likewise the
spatial indexing method used for tile lookup. The server architecture is
based on "tile streaming" so that often only one tile per object needs
to be kept in main memory at a time, thereby enabling small servers to
process large arrays. On the other hand, transparent near-line tertiary
storage support wipes out size limitations.

The rasdaman group has extensively researched in optimization, resulting
in techniques like query rewriting, pre-aggregation, just-in-time
compilation of query fragments, and GPU utilization, all of which have
been proven highly effective in performance evaluations. At ACM PoDS
2007, Rona Machlin has termed rasdaman the "most comprehensive effort"
in array DBMS.

Rasdaman is in operational use in geo service applications run by both
industry and governmental authorities since many years. For example, the
French National Geographic Institute (IGN-F) maintains a dozen-Terabyte
airborne image with rasdaman/PostgreSQL. Recently, the Open GeoSpatial
Consortium (OGC, www.opengeospatial.org) has published the Web Coverage
Processing Service (WCPS) standard which offers a geo raster processing
language based on the concepts and experience of rasdaman.
