Background: Agoda online platform

About Agoda

See The World For Less

Agoda is an online travel platform that brings high-value and rewarding travel experiences to people all

over the world through the Agoda app and Agoda website. Our mission is to empower everyone to be a

traveler by offering affordable deals on hotels, flights, activities, and more, with an Agoda booking

experience that is hassle-free from start to finish.

Since the Agoda company was founded in 2005, we’ve made searching and booking travel as easy and

stress-free as it should be. Agoda is now considered one of Asia’s leading travel-tech companies with

millions of registered customers supported by a truly diverse team of more than 6,600 people in 31

markets and Agoda customer service available 24/7.

Visitor Numbers

In accordance with Agoda.com’s obligations under the EU’s Digital Services Act (DSA), we estimate that

the average monthly recipients* of the Agoda.com service in the European Union from 1 February 2023

up to and including 31 July2023, is well below 45 million.

This is only an estimate and is based on the data available to Agoda.com at this time, and the limited

guidance in the DSA. This estimate is required to be published under the DSA and should not be used for

any other purpose. The methodologies used to estimate average monthly recipients as defined in the DSA

require significant judgement and design inputs, are subject to data quality, other factors and limitations,

and inherently are subject to statistical variances and uncertainties. These estimates may be revised

upwards or downwards as Agoda.com refines its approach and in response to the publication of

methodology by the European Commission.

Please refer to the website for metrics we consider relevant to Agoda.com’s business.

* ‘recipient of service’ is defined under the DSA to mean “any natural or legal person who uses an

intermediary service, in particular for the purposes of seeking information and making it accessible”. This

requires counting users to whom information was displayed by the Agoda.com service, even if that user

did not make a transaction.

Agoda Platform-to-Business (P2B) Complaint Handling Annual Report (EEA)

For the period: 1 January 2022 to 31 December 2022. Complaints received in the EEA: 1,514 from

209,944 partners. Complaints received were related to the following areas:

• 45% booking rate/price related.

• 42% payment related.

• 11% system issues/bug related.

• 2% property status/content related.

We resolved 100% of the complaints in 2022, of which:

• 68% of the cases were resolved within 3 days.

• 20% of the cases were resolved within 4-7 days.

• 12% of the cases required 7 days or more for resolution.

From January 2022 to date, no mediation cases have been filed by any partner in the EEA.

From an enterprise system integration perspective, please outline a collaborative business process

for Agoda's e-business operations (such as booking hotels or airline tickets) and fulfill the following

requirements:

Project Brief (4 marks)

Provide a description on:

• the group meeting schedule or plan, each member’s role in the project,

• identify risks and ways to manage risks,

• identify ways to communicate between members,

➢ log recording for each meeting, including discussion and any dialogue between members in

relation to the project.

Note: all group members need to contribute to the project. The description and log need to be submitted together

with the four tasks.

Task 1 Collaborative Business Process and EAI (4 marks)

The objective of this task is:

• To use BPMN notation (Week 2 lecture) to draw a collaborative business process for the Agoda

(booking a hotel or booking an air ticket) in which you need to show partners (such as the company, the

seller and the users, etc.), how they interact, and how information/messages are exchanged. In this case,

the partner systems can be custom management system, booking system, payment system, shipping

system, information system, etc. (The process should be straightforward and not as complex as the one

in Assignment 2.)

• There are different ways to design and implement this collaborative business process. Design and draw

an EAI system that support the User makes the inquiry to different systems and make a decision in

booking hotels or air tickets.

• Explain how User’s inquire is processed in your EAI system. You must state any assumptions your group

deems necessary.

Task 2 Web Service Design (4 marks)

Suppose you are creating the components of online booking as web services, which allows users and sellers to

create applications. You are required to:

1. Identify the two (2) necessary functions of these services. You can make (and state) your assumptions

based on your experience in using online booking system;

2. For each of the above functions (from point 1), identify the input/output messages;

3. Use WSDL interface definition constructs to specify the above identified functions with input/output

messages.

Task 3 XML Schema Design (4 marks)

For the above input/output messages, write their XML Schemas. You need to include the following:

• Two different ways of specifying complex types, one is defined inside the element, the other defines a

complex type first, then (re-)uses it as a complex type of an element;

• Use constraints on the values of a simple typed element, on the occurrence of elements;

• Pick up one xml schema, construct a sample xml document.

• Validate your code with the schema and show the steps with screen shots using the online validator of week

8 practical (see xml validator https://www.corefiling.com/opensource/schemaValidate.htm).

Task 4 Discussion (4 marks, @ 600 words)

“The current system is basically a portal for a collection of documents without proper integration”, from

this description we can image the documents stored there are of different formats with different structures. The

challenges are how to bring all the information together in a uniformed interface for search and query. Use what

you have learned in the unit to discuss the following:

• The possible issues relating to the integration of all the components in this E-Business

System (from different layers/aspects) using examples;

• The possible technologies potentially used to support system integration at various levels/aspects;

• The options and considerations of the technologies along with their advantages and disadvantages

Submission: one submission per group, together with the project description and log.

Zero Tolerance for plagiarism:

You are required to use your own words to provide the descriptions and explanations. All submissions will be

checked for plagiarism. No Chatgpt. No Generative AI. Any cases will be reported to the faculty for

disciplinary action, and the marks of the assignment and the unit will be withheld until the case has been

resolved. See Macquarie University’s code of conduct for the details of the process:

https://students.mq.edu.au/study/getting-started/student-conduct.

Submission

Place your soft copy in your assignment 3 submission folder on iLearn. Please submit a single PDF file containing

your source code. There is no word limit. The document should begin with a table of contents that outlines your

work, and make sure to include the names and student IDs of all group members.
