CIS020-2Introductory Programming and Modelling

Assignment No. 2 – Case Study

Work with colleagues in your assigned group to model and implement your group’s casestudy.

Submit a word processed document detailing the work that you have done as part of thegroup. This document must include your student ID and page numbers in the footer. You willbe marked only on the work you submit in this document and your contribution to the grouppresentation.

Peer assessment forms will be made available.

The following Learning Outcomes will be addressed in this assignment:

LO1 Recognise and apply basic programming concepts related to high level programming,such as data types, identifiers, sequences, selections and iterations.LO2 Become familiar with and apply the essential modelling concepts related tounderstanding systems such as input, output, processes and data storage.LO3 Implement a program following the stages of analysis, design, implementation andtesting using an up-to-date modelling language and a modern high level programminglanguage.LO4 Gain an elementary understanding of modelling and programming systems within anObject Oriented (OO) environment.LO5 Demonstrate good practice in coding, use of test data and documentation.

Tasks

For the case study attached.

Produce a model of the system using the following modelling techniques from UML:1. Use Cases;2. Activity;3. Communication;4. Sequence;5. Class;

Code and test the Property Renting system using Java. Please do consider thedocuments identified as a, c, d, e, and f in your implementation. Try to develop GUIs foreach of the forms you need to use within the system as user interface.

The UML model should incorporate with whole system.

NoteThe tutors for this module will help you to select appropriate use cases to modelfurther and implement.

Deliverables

These following items are deliverable from the completion of the tasks described in theinstructions:

From each Group:

Each group should submit the word processed report developed as described aboveincluding:

1) UML Use Case diagram completed with accompanying text explaining the behaviourof the system.

2) UML diagrams (Activity, Communication, Sequence) analysing at least 3 scenarios ingreater detail.

3) UML Class diagrams illustrating the class structure of the java implementation.

4) Java code source code for the system, complete with explanatory comments

From each Individual:

1) A peer review form reporting on your interaction with other members of the group

Delivery method:

Combine these files into one and Submit via TurnItIn facility made available forAssignment2.

Case Study

Property Renting

Each client is invoiced monthly, but there are some exceptions which are four weekly and

weekly. Before the client is invoiced, a ‘tenant’ payment has to be received from the tenant.If the tenant pays by cheque, there is a ten-day delay before the cheque is cleared (through the

banking system). If the tenant pays by cash, standing order or housing benefit, the client is

invoiced immediately.

Every invoice is duplicated for office records, and a copy is forwarded to the accountant at

certain times. A statement of accounts may be useful this purpose, thus itemising several

transactions on one page which could include more than one property.

Expenses are recorded for each property, which are deducted from the client’s account beforethe client receives any payment.

Tenancy agreements are renewed six monthly and must be flagged.

Commission charged is variable but generally there are five levels. Payment clearance must

be flagged, so invoices can be printed in one go.

The system must be able to view all details and carry out the following tasks:

1. Client – add, amend and delete;

2. Property – add, amend, and delete;

3. Tenant – add and delete;

4. Calculate VAT @ 17.5% and zero;5. Produce quarterly, yearly and ‘to-date’ report totals of all money transactions;

6. Payments made by clients for repairs etc, are not to be included in VAT or commissioncalculations;

7. Usually payment of rent relates to one property, but if a client has more than one

property, money can be deducted from the client’s total (although no rent has been takenfor that specific property;

8. Deposits paid by tenants, are not to be included in VAT or commission calculations and

may be returned to the tenant at the end of their tenancy;

9. If required, money may be deducted from the deposit for non-payment of rent and

damage to the property;

10. The financial year needs to be changed from 1st

October – 30th

September, to 5th

April – 4

thApril;

11. Financial archive records are required, therefore ‘end of financial year reports’ must be

developed that will identify previous client and tenant money transactions.
