data modelThe description of the structure and organization of the data in a database. The data model tells you all the tables names, their contents, and how they are related to, and linked with, one another. The actual implementation of a data model is called the database schema. For the flat files available in the DAS, the data models are available at http://www.sdss.org/dr1/dm/flatFiles/FILES.html.
