This assignment counts as 15% of your final mark.
This assignment is an individual piece of work.
The deadline is strict. Penalties for late submissions apply according to the University rules.
Context
This assignment is about developing and using services in C#. The programming language for this
assignment is strictly C#. Marking will consider good coding style (comments in your code, proper
indentation, good structuring of the code, choosing appropriate C# types and constructs, good OO
design, etc.) and marks will be deducted for bad style. As database I expect you to use MySQL as
explored in the lab work (this can be used locally on your laptop/ computer or be the departmental
mysql server (mysql.mcscw3.le.ac.uk)).
Tasks
A rental company offers different types of properties. All properties have records that contain their
address, current status (let/empty), end of current lease arrangement (if applicable). Houses have
additional information on whether they are allowed to be let to students and/or have multiple
occupancy or not. Student flats have a number of allowed occupants. Non-student flats have an
indication as to whether pets and/or children are allowed.
1) You must develop and implement a sensible class structure to capture these properties and
provide methods for their features (get_basic_information will return address, etc, and there
should be methods for the multiple occupancy, student lettings etc allowing access to the
other data in convenient ways. Develop a console programme creating some property
objects to test your operations. You need to decide on the class structure and you must
consider how to use object-oriented concepts to best solve this. [6 marks]
2) Develop a simple database for properties (I am not expecting any normalisation) and insert a
few items. The database should have an additional table ‘lettings’ with the field (rental-no
(primary key), property_no (foreign key), available) which will allow convenient access to
all currently available properties. Choose appropriate data types. [no marks for this part]
3) Develop a WCF service that offers operations to
a. Search for a property by post code (no other searches are needed).
b. Enter a new property into the database (assume that all data will be provided, i,e.
you do not need any domain specific error handling).
c. Get a list of all available properties that can accommodate students.
Remember to consider the design for suitable web services interfaces! [10 marks]
4) Develop a client console application to check the webservice, that has the following
features:
a. It has a textual menu to choose to a) search for property, b) enter new property or c)
show available student lets. This will be used to invoke one of the following
functionalities. Obviously users should be returned to the menu after running one of
the operations.

b. Search: Gathers postcode from the user, invokes the UpperOperator from the SOAP
service at https://campus.cs.le.ac.uk/tyche/ws-temp/UpperOperator.wsdl to convert
the entry to upper case before using the service from 3)a. to search and finally
displays the result on screen.
c. Add New: Gathers information from the user, converts the postcode to uppercase
(use the service as in part b) and then inserts the property into the database using the
service from 3)b.
d. Available student let: Displays the list of all available student lets obtained through
the service from 3)c. [6 marks]
Please note that I am not expecting you to make things too complicated; focus on the right
structures and the web service related parts. Do not spend much time on creating complex user
interfaces. Also, do not spend time on error handling (you can assume for the purpose of this
exercise that users will enter the right type of data).
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). Please only submit zip files (Windows can create
these by right clicking on the folder and saying “add to compressed folder”; do not
submit tar or gzip or other archives). If the file is too large to submit on Blackboard use
filedrop.le.ac.uk for your submission – there is no need to submit on filedrop if you
manage to submit on Blackboard.
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. This should also
contain the Create Table statement(s) for your database. 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. Guidelines for late submissions are explained in the
study guide; however, be reminded that being late – even by a minute – will incur a significant
penalty in terms of marks lost.
