Question

Draw the CONTEXT Digram for the given case study below:

"UAETourism & Travel Agency LLC" from this year on, the tickets will be sold in three distinct ways: traditionally, i.e. by the two events agencies, in electronic format directly on the festival website, and through SBB. All parties will have access to the same unique tickets database of the new system, to avoid double selling. A partnership with the SBB railway company needs to be set up, such that SBB can sell combi-tickets including both the festival admission fee and the train ride to the festival venue at reduced price, from anywhere in Dubai. This way, more music fans would have easier and cheaper access to UAETourism . Moreover, the system will have to be extended to support not only Arabic, but also English, French and Italian. Since tickets will also be sold online, SecurePayment Inc. will be contracted to provide and ensure the security of the online payment service. The UAETourism event manager will take care and negotiate all these details with the involved parties. Additionally, upon arrival at the festival venue, each participant has to self-check in at a touch screen terminal, which scans the barcodes on his/her ticket and issues a bracelet with an electronic chip. This can be used to load money, such that whenever (s)he wants to purchase snacks or beverages, (s)he does not have to use cash any more, thus reducing waiting times. This measure was initiated by the program manager and will be deployed by SmartSolutions Inc. Lastly, according to the cantonal laws, the way the payment transactions are performed has to be audited by an external company at the end of the festival, since this is a public event, where the municipality of UAE is also involved – allowing free use of the public space.

In the diagram, the main entity is "UAETourism & Travel Agency LLC." It interacts with three different parties to sell tickets: events agencies, the festival website, and SBB railway company. All these parties have access to the same unique tickets database to avoid double-selling.

To ensure secure online payment services, "SecurePayment Inc." is contracted. They handle the online payment transactions.

The self-check-in and electronic payment system is implemented by "SmartSolutions Inc." Upon arrival at the festival venue, participants use touch screen terminals to self-check in by scanning the barcodes on their tickets. They are then issued a bracelet with an electronic chip, which can be used for purchasing snacks or beverages without cash.

As per the cantonal laws and involvement of the municipality of UAE, an external "Auditor Company" is responsible for auditing the payment transactions at the end of the festival. The public space is made available for the festival.
