The Catalog Archive Server Jobs System, or CasJobs, is an online workbench for large scientific catalogs. It is designed to emulate and enhance local free-form query access in a web environment.
CasJobs provides both synchronous and asynchronous query execution, and a 'History' function records queries and their statuses. Each user gets a personalized, server-side database called 'MyDB', which enables persistent table, function, and procedure creation. MyDB data can be downloaded in a variety of formats and shared between users via the 'Groups' mechanism.
CasJobs provides multiple interface options, including a browser client and a java-based command line tool. It also offers SOAP-based web services for managing user accounts, jobs, user groups, and servers.
