(Đề thi thực hành trên EOS)
Saigon Tourist (ST) company is one of the leading companes in the tourism and travel industry
in Vietnam. To keep up with the trends of the Internet era, the company's CEO has decided to
develop a system called Online Travel Booking Software (OTBS) that allows customers to
book tours, track their progress, and support the management of the tour execution process...
CEO expected that the OTBS should be designed to allow customers to conveniently search,
compare, and reserve travel-related services such as flights, hotels, rental cars, and holiday
packages. The system must provide a user-friendly interface, secure transactions, real-time
availability, and integration with external service providers (airlines, hotels, travel agencies). It
should also support multiple payment methods, booking confirmations, cancellations, and refund
processes. The OTBS must remain consistently available, especially during peak travel seasons
and promotional events. Customers expect that once they start a booking, the process will not be
interrupted by unexpected downtime or system crashes. If an error occurs, the system should
gracefully recover and either resume the transaction or securely roll it back to prevent duplicate
charges or incomplete reservations. Redundancy and backup mechanisms ensure that even if one
server fails, the service continues without disruption.
Further more, speed is crucial for customer satisfaction. The website should deliver search
results for flights or hotels within a few seconds, even when querying multiple external providers.
The platform should scale to handle thousands of simultaneous users during high-demand periods,
such as holiday sales or special promotions. Pages, especially those involving transactions, must
load quickly on both desktop and mobile devices, and the system must optimize performance
100%
