Fw: [Pgsphere-dev] abstract to ADASS-XIII conference

[Robert Creager <Robert_Creager@LogicalChaos.org>]

Hey folks,

I'm sending this to the list as a favor to the developers of pg_sphere
(http://gborg.postgresql.org/project/pgsphere/projdisplay.php).  I'll
pass on any comments.  Would this abstract make you interested enough to
look further?  If no, what could be changed?

Comments?

Thanks,
Rob

Subject: [Pgsphere-dev] abstract to ADASS-XIII conference


Hi everybody!

I'm presenting the draft of the abstract to ADASS-XIII conference, which
I
should submit before July, 18th. Any feedback is welcome.

PostgreSQL: the suitable DBMS solution for astronomy and astrophysics.
======================================================================
We consider PostgreSQL, open-source RDBMS distributed under BSD license,
as one of the best database solutions for astronomical and astrophysical
tasks. We present a comparison between several available commercial and
non-commercial database solutions from the point of view of astronomical
applications. PostgreSQL is shown as the most advanced free distributed
RDBMS.

Extensibility is the most important advantage of this RDBMS. PostgreSQL
allows to create user-level functions executed by the database backend
using shared libraries. With GiST access methods it is possible to
create
indexable user datatypes and it is very important for "non-standard"
tasks
usual for science. We describe the possibilities of the backend
programming for PostgreSQL.

We present pgSphere - ready for use contribution module for PostgreSQL
which allows to deal with geometric objects in spherical coordinates.
This
module demonstrates all the possibilities of backend programming using
GiST interface for spatial indexing of spherical data. PgSphere can be
very useful in astronomy and geo-sciences. Performance tests are
presented.

We describe the concepts of pgAstro - contribution module based on
pgSphere engine, which will include a lot of specific functions and
methods useful for astronomical and astrophysical purposes.

We conclude that PostgreSQL is the most suitable database solution for
astronomical applications and it can be very useful for different VO
goals.
