The SuperCOSMOS Science Archive is an implementation of the 
legacy SuperCOSMOS Sky Survey flat-file data in 
Windows/SQL Server as opposed to 
the flat-file system accessible via the SSS web interface.
It consists of data from digitised sky survey plates taken with the UK Schmidt 
telescope (UKST), the ESO Schmidt, and the Palomar Schmidt.
The data is organised in schemas, which include
tables, views, and constraints.
