COMP08034 Structures & Algorithms – Coursework

Session 2019-20

This coursework can be carried out either individually or in pairs. Submission should be via Moodle. You are to implement a dynamic data structure to maintain details of current projects for an IT company.

You are advised to develop the program one step at a time and keep a copy of the version for each step which should then be included in your submission. In addition to the marks at each step, there are 25 marks for documentation, programming style, testing and an individual report.

Your individual report should justify your choice of data structure and testing of the system. You should discuss any difficulties you encountered and any parts of your solution that are not working correctly.

A computer company which has many projects being undertaken at any one time would like a system to hold information on all the current projects as well as details of the employees working on each project. An employee only works on a single project at a time.

The data to be stored for each project is:
Project Title e.g. Web site creation
Expected start/end dates e.g. 01/01/20 – 31/05/20

The data to be stored for each project team member is:
Name e.g. Joe Bloggs
Employee Number e.g. 999999
Division e.g. Web Development

The features required by the Company include:
Add details of a new project
Add details of a new member of a specified project
Display the details for a specific project
Display all the details for all the projects
Remove a particular employee from a specified project
Remove a project from the system


Step 1: Functionality is worth 25 marks
create a Company class with suitable attributes to represent each project as well as a link to each project.
Using an appropriate dynamic data structure, write a CompanyTest class that offers a simple menu to add a new project, find and display a specific project, remove a specific project and to display the details of all the projects currently being carried out by the company in alphabetical order of project title;
Use appropriate exception handling.

Step 2: Functionality is worth 15 marks
Create a TeamMember class with suitable attributes;
Using an appropriate dynamic data structure, different from the one used above, write a TeamMemberTest class that offers a simple menu to add a new team member, find and display a specific team member, remove a specific team member and to display the details of all the team members;

Step 3: Functionality is worth 35 marks
Combine the two structures above modifying the necessary methods so that the resulting data structure is a binary search tree; You will need:
oAn addProject method that adds projects to the structure;
oan addTeamMember method that interacts with the user to select a project to add the project team member details to;
oa removeTeamMember method to remove a specific team member from the system if they are no longer a member of the team;
oa removeProject method to remove a project from the system;
oa displayTeamMembers method which interacts with the user to select the project to display and which then displays all the team members for that project;
oa displayAll method to display the information on all data for the projects including all the team member info, in alphabetical order of project;
provide a method to display the number of members in each project team.
add JUnit classes that test your solution.
Submission

Due Date: Friday 17th April 2020 @ 10pm

Upload your work via Moodle
create a folder based on your banner id e.g. B00123456. If the coursework is done in pairs, then include both banner ids.
copy ALL the projects for the different versions of the program into this folder as well as your report
create a compressed zip version of this folder
oin Windows Explorer, select the folder with the right button then select Send To then Compressed (zip) Folder
select the Coursework Submission link in the Coursework tab on Moodle and follow the instructions to upload the zip file
