This assignment counts as 15% of your final mark.

This assignment is an individual piece of work.

The deadline is strict.

Context

This assignment is about understanding and modelling workflows, implementing web service

interfaces in C# to match a design and preparing deployment to Azure.

Scenario

“With semester ending and the holiday season emerging many like to go on a short trip.

MyVacation offers travel for students needing a short break. It allows the student to specify

when they want to go (Easter, Christmas, Summer), which University they attend and what

their budget is. The service will identify the vacation periods from a University Term Times

service. It will then identify a number of destinations that are within budget at the given

time using a holiday package broker. Those packages start and end with a flight and include

and transfers from airport to hotel, the hotel and meals – so nothing to worry about from

when you step on the plane. A service called transport-identifier will find a way from the

University town the student attends to the right airport and the cost there-off. MyVacation

decides based on overall cost (airport transport plus vacation cost) which is the cheapest

break and will book that for the student. The student’s credit card will be charged with the

cost arising from the booking and a booking confirmation number and itinerary are returned

to the student.’

NOTE: this is simplified and you do not have to worry about availability of tickets or their

prices; you also do not need to consider exceptions on the payment side.

Tasks

1) Analyse the scenario and decide on which 3 services are needed by the process described

above. Decide what interfaces are needed (each service needs one interface).

a. Draw a process diagram for your solution that shows the flow of the process as well

as the interactions with the partners. [6 marks]

b. List the interfaces of the process and service. [3 marks]

Note: this can be done on paper and scanned/ photographed or in PowerPoint. Please try to

save the design as pdf file were possible.

2) Implement the three needed partner services either as C# or Workflow services; the focus is

entirely on the interface (so through their implementation they can all return hardcoded or

randomly generated values; specifically there is no need to connect to a database here and

there is no need for complex logic for this part). Keep it simple, but have three services (or

one with three interfaces) with good interface design and appropriate data types for the

interfaces.

3) Make changes required to the project to deploy the services to the Azure Cloud. (You can

test the result in the cloud emulation environment or on a free trial Azure account. Note

however that there is no need to actually deploy the services and workflow).

[3 marks]

Please note: Some parts of the specification above might be imprecise – welcome to the real world!

Please make your own assumptions and fill in the gaps – just describe your assumptions in your

submissions.

Submission:

You need to submit via Blackboard. The submission should be made using the Blackboard

assignment feature. Once you select this assignment from assessment you will be taken to a different

screen that allows download of this description and the coursework coversheet as well as submission

of the solution.

Your submission should include

A zip archive containing the folder tree with your solution (so the folder that contains

the .sln file and all subtrees thereof). This should not be much bigger than 1MB – let me

know if it is much bigger (>10MB) and we can agree on how to submit. Please only

submit zip files (Windows can create these by right clicking on the folder and saying

“add to compressed folder”).

A file with your design for Task 1 (this can be a ppt or a photo/ scan of a hand drawn

diagram).

A brief description of the steps required to Azure enable the service and deploy it to the

cloud (no pictures expected, just a textual description). Note that someone who has not

done this before should be able to follow what is going on. This should be a plain text

file or text added to the description (see next bullet).

A description (typed into the submissions text box in blackboard) which tells me which

tasks you have attempted and in which files the tasks are addressed. It is essential that

you include the description in this way.

A completed coursework coversheet (print an sign the pdf file and include a scan/ digital

photo in the Blackboard submission).

Once the files are added and you are happy to proceed with submission click the submit button

(save will not transfer your submission, but allow you to store work at intermediate stages). Once

you have submitted you cannot resubmit.

If you do not follow the submission guidelines your work might not be marked and most certainly

will not be marked in the normal timeframe.

Late submissions will incur a penalty in accordance with the University guidelines.
