Publishing catalogues with DSA

Abstract

The AstroGrid DSA (Data Set Access) component is a tool for making tabular data stored in an RDBMS (relational database) available on the VO. It can plug into a wide variety of different database systems and makes the data accessible for ADQL (Astronomers' Data Query Language) queries as well as cone searching tables. The aim of this hands-on session is to show how to publish tabular data, stored in an RDBMS system, using the AstroGrid DSA. Sample data will be made available, but participants are also encouraged to try publishing some of their own data. This may be installed on the participant's laptop, or, firewall issues permitting and subject to appropriate ODBC (object data-base connection) access, on a remote RDBMS. Participants may choose to participate in a "step-by-step" assisted-installation group, using pre-prepared sample data. Alternatively, they may choose to work independently at their own pace, using the supplied documentation (with support from AstroGrid advisors as needed).
