Title : Optionnel

Text : A site-data descriptor group is a collection of individual records, each of which is a concatenation of the agency code, site identifier, and data-descriptor number. This collection of data is stored in a Group File under ADAPS and is used primarily in data retrievals. The user can have more than one Group File with different sets of stations selected, each stored as a separate Group File, and probably will have several in order to have greater retrieval flexibility. Chaque paragraphe sera un test.
