Step 1: Defining Global Distribution Systems (GDS):
A GDS is a massive worldwide computerized network that connects travel agencies, booking sites, and corporate travel planners with hospitality providers, airlines, and car rental companies to enable real-time bookings.
Step 2: Classifying the Options:
• IDS (Option A): Internet Distribution System, which connects hotels directly to online travel agents (OTAs) rather than traditional travel agencies.
• Opera (Option B): A widely used Property Management System (PMS) developed by Oracle, designed for managing on-property operations (room inventory, check-in, cashiering).
• Sabre (Option C): One of the premier global GDS networks, originally developed by American Airlines. Other major systems include Amadeus, Galileo, and Worldspan.
• Shawman (Option D): A specialized POS/PMS software suite.
Therefore, Sabre is the correct representation of a GDS.
