For an airlines company identify three operational applications that would feed into the data warehouse. What would be the data load and refresh cycles?

Three operational applications for an airline company that would feed into a data warehouse include flight operations management (tracking schedules and delays), customer relationship management (CRM) (managing passenger data and interactions), and revenue management systems (optimizing pricing and inventory). The data load for flight operations could occur in near real-time to accommodate schedule changes, while the CRM system might update daily to reflect new customer interactions. Revenue management data could be refreshed weekly to analyze booking trends and optimize pricing strategies.
