Data used by ATIS starts as a reservation made by a travel agent or (directly) by a traveler.  These data are entered into one of the major reservation systems; Galileo, Sabre, Apollo, WorldSpan, Amadeus, etc.

From there, data is "interfaced" to one of a large number of travel agency backroom accounting systems.  Within these systems, changes are made as needed to the data and some reporting can be done.  The primary purpose of these systems, however, is the ability to report to the Airline Reporting Corporation (ARC).

ATIS uses the data contained in these backroom systems.  The data is exported from the backroom accounting system and imported into ATIS. In some few instances, the backroom system does not have an adequate export system.

For these instances, ATIS has available special utility program called Extractors that copy the appropriate tables and rows of data needed for ATIS.

Currently, Extractors exist for the following backroom accounting systems:

• GlobalWare
• TRAMS For DOS
• TRAMS For Windows
• TravCom
