CasJobs is an online workbench for large scientific catalogs, designed to emulate and enhance local free-form query access in a web environment.

Some features of this application include...

Both synchronous and asynchronous query execution, in the form of 'quick' and 'long' jobs.
A query 'History' that records queries and their status.
A server-side, personalized user database, called 'MyDB', enabling persistant table/function/procedure creation.
Data sharing between users, via the 'Groups' mechanism.
Data download, via MyDB table extraction, in various formats.
Multiple interface options, including a browser client as well as a java-based command line tool.

The web interface for CasJobs is fully compatible with recent versions of the following browsers:

Internet Explorer
FireFox

CasJobs is partially compatible with recent versions of the following browsers:

Mozilla
Opera
Safari
