GeneralGuidelines• The work you submit must be in your own words. If you use a quote or anillustration from somewhere you must give the source.• Include a list of references at the end of your document. You must give allyour sources of information.• Make sure your work is clearly presented and that you use readilyunderstandable English.• Wherever possible use a word processor and its “spell-checker”.

The coursework must besubmitted as one document in a report format with the full implementation of the code projectembedded as an object at the end of the report.Assignment Scenario:Primrose Ltd is a construction company. They build affordable homes for key workers. Their workforce is mostly shift-based. Currently they track employee working hours using an excel file. Thenumber of hours recorded on the excel file are used for the purposes of calculating employeesalaries at the end of every month. Recent growth in the company means their file-basedemployee hours tracking system is no longer adequate.You have been tasked to create a database driven application to replace the current file-basedsystem. The new system will have the following key features:• Employees will be registered in the system by an admin staff. The following information willbe required: first name, last name, birth date, mobile and email.• Employees will have login accounts• There are two types of employees, full time or part-time• Employees will be able to login at the start of their shift and logout at the end of their shiftusing their user name and password• Logged-in employees will be displayed on a list on the home screen and once they logout,their name is removed from the list of logged-in employees.• Hours worked will be calculated from the employee’s login/logout times• Admin staff can see all employee’s data including hours workedAdvanced optional features:• Employees can search and view their data including hours worked but not anotheremployee’s.The application you develop will be either a desktop with a GUI or web application. Whichever ofthe two will be decided by what is used in the teaching of this course.Department of Information Technology Page 3 of 6LO1C# is an OOP language that allows OOD paradigms such as Abstraction Encapsulation,polymorphism and Inheritance. You need to examine the characteristics of the Object-orientatedparadigm in relation to the given scenario. You need to discuss a range of design patterns fromeach of the creational, structural, and behavioural patterns and analyse the relationship betweenthe object-orientated paradigm and the design patterns to be used in this application.N.B. You may use code snippets to aid your discussion. Any code snippets that appear inyour submission must be within the context of the given the scenario. Textbook examplesare not acceptable.LO2In designing an object-oriented solution, it is important to make use of modelling tools such asUML diagrams. Your task here is to produce a UML Class diagram to capture the relationships(generalisation, specialisation, composition) between the entities identified for the implementationof an OO solution to the scenario. Your UML class diagrams should be specific to the designpattern you will use in this implementation and it must be complete with the necessary fields andmethods that will be implemented in LO3.N.B. All UML diagrams and/or code snippets included in your submission must be withinthe context of the given the scenario. Textbook examples are not acceptable.LO3Based on your UML class diagrams in LO2 you are required to develop the application in C# byfollowing object-oriented programming paradigm. The application must implement all the featureslisted in the given scenario above. You will select an appropriate design pattern (with justification)to implement and evaluate the pattern used. Use Visual Studio 2019 community edition or anyother IDE of your choosing as your development tool.N.B. DO NOT fill this section with screenshots of code and/or UI. You must use this sectionto explain the key elements of your implementations, the rationale for your approach etc,e.g., how your implementation relates to your design in LO2, its relation with the designpatterns discussed and your evaluation and test results. This can be supported with codesnippets. Your complete code will be submitted as an embedded object in the appendixsection.LO4Discuss a range of design patterns (Creational, structural, and behavioural pattern types) withreference to relevant examples as applied to the given scenario. Reconcile the most appropriatedesign pattern to the given scenario and critically evaluate the design patterns against a range ofscenarios with justification of your choices.N.B. Any models, code etc. included in this section must be within the context of the giventhe scenario. Textbook examples alone are not acceptable.AppendicesNote: You should attach all the supporting documents as a separate file in the appendix section ofyour assignment.Department of Information Technology Page 4 of 6Relevant InformationTo gain a Pass in a BTEC HND Unit, you must meet ALL the Pass criteria; to gain a Merit, youmust meet ALL the Merit and Pass criteria; and to gain a Distinction, you must meet ALL theDistinction, Merit and Pass criteria.1.

Preparation guidelines of the Coursework Documenta. All coursework must be word processed.b. Avoid using “Text box” in writing your assignment.c. Document margins must not be more than 2.54 cm (1 inch) or less than 1.9cm (3/4 inch).d. Font size must be within the range of 10 point to 14 points including the headings and body text(preferred font size is 11) in Arial.e. Standard and commonly used type face, such as Arial and Times New Roman, should be used.f. All figures, graphs and tables must be numbered.g. Material taken from external sources must be properly referred and cited within the text using Harvardsystemh. Do not use Wikipedia as a reference.Department of Information Technology Page 5 of 63. Plagiarism and CollusionAny act of plagiarism or collusion will be seriously dealt with according to the College regulations. In thiscontext the definitions and scope of plagiarism and collusion are presented below:Plagiarism is presenting somebody else’s work as your own. It includes copying information directly fromthe Web or books without referencing the material, submitting joint coursework as an individual effort.Collusion is copying another student’s coursework, stealing coursework from another student andsubmitting it as your own work.Suspected plagiarism or collusion will be investigated and if found to have occurred will be dealt withaccording to the College procedure (For details on Plagiarism & Collusion please see the StudentHandbook).4. Submissiona. Initial submission of coursework to the tutors is compulsory in each unit of the course.b. The student must check their assignments on ICON VLE with plagiarism software Turnitin to makesure the similarity index for their assignment stays within the College approved level. A student cancheck the similarity index of their assignment up to five times in the Draft Assignment submissionpoint located in the home page of the ICON VLE.c. All Final coursework must be submitted to the Final submission point into the Unit (not to theTutor). The student would be allowed to submit only once and that is the final submission.d. Any computer files generated such as program code (software), graphic files that form part of thecoursework must be submitted as an attachment to the assignment with all documentation.e. Any portfolio for a Unit must be submitted as an attachment in the assignment5. Good practicea. Make backup of your work in different media (hard disk, memory stick, etc.) to avoid distress due toloss or damage of your original copy.6. Extension and Late Submissiona. If you need an extension for a valid reason, you must request one using an Exceptional ExtenuatingCircumstances (EEC) form available from the Examination Office and ICON VLE. Please note thatthe tutors do not have the authority to extend the coursework deadlines and therefore do not askthem to award a coursework extension. The completed form must be accompanied by evidencesuch as a medical certificate in the event of you being sick and should be submitted to theExamination Office.b. Late submission will be accepted and marked according to the College procedure. It should be notedthat late submission may not be graded for Merit and Distinction.c. All late coursework must be submitted to the Late submission point into the unit (not to the Tutor)in the ICON VLE. A student is allowed to submit only once and that is also treated as the finalsubmission.d. If you fail in the Final or Late submission, you can resubmit in the Resubmission window.7.
