Omni GRS

Global Reservation System (GRS) is a proprietary application written in the "Informix 4GL" programming language used by Omni employees in Omaha (call center) and at hotels across North America to create, modify, and cancel reservations in Omni's proprietary Informix CRS database.

Interfaces
Employees use GRS. No automated systems "interface" with GRS. GRS is an application humans use to view and manipulate data in CRS. 99% of its data impact is to CRS, but in some cases GRS triggers data manipulation in other systems. The details of those impacts is detailed here.
