Instructions
Consider the following Case Study Scenario for ‘Holmes Software Engineering’
A relational database is to be designed for a medium sized Company dealing with industrial applications of computers. The Company delivers various products to its customers ranging from a single application program through to complete installation of hardware with customized software. The Company employs various experts, consultants and supporting staff. All personnel are employed on longterm basis, i.e. there is no short- term or temporary staff. Although the Company is somehow structured for administrative purposes (that is, it is divided into departments headed by department managers) all projects are carried out in an inter- disciplinary way. For each project a project team is selected, grouping employees from different departments, and a Project Manager (also an employee of the Company) is appointed who is entirely and exclusively responsible for the control of the project, quite independently of the Company’s hierarchy. The following is a brief statement of some facts and policies adopted by the Company.
• Each employee works in some department.
• An employee may possess a number of skills
• Every manager (including the MD) is an employee
• A department may participate in none/one/many projects.
• At least one department participates in a project.
• An employee may be engaged in none/one/many projects
• Project teams consist of at least one member.
Deliverable Descriptions
For the above mini-case study, you are to analyze the data requirements and develop a set of relational tables to suit the above case study.
• Draw and ER diagram depicting the relational database.
• Make sure the tables are normalized.
• Build the Database in PostgreSQL (storing your DDL statements in a script)
• Add test data to the PostgreSQL database (again store these DML statements in a script), one of the employees you add must have an employee ID the same as your own Student ID. This employee must also be part of a team working on some project
• Develop a set SQL queries to query this database (there should be at least 4 queries)
? at least 2 queries should joint multiple tables (1 should join at least 3 tables)
? at least one query should show the employee with the ID the same as your student ID
For each query, you should show the output from executing the Query in PostgreSQL by cutting and pasting the PostgreSQL output into your assignment just under the Query.
This should be demonstrated to your tutor in class during a tutorial after the due date to be advised by your tutor.
Submission Guidelines
The day and time of the due week that the assessment must be submitted will be announced by your subject coordinator.
Your documents should be a single MS Word or OpenOffice document containing your report. Do not use PDF as a submission format,
All submissions will be submitted through the safeAssign facility in Blackboard. Submission boxes linked to SafeAssign will be set up in the Units Blackboard Shell. Assignments not submitted through these submission links will not be considered.
Submissions must be made by the due date and time (which will be in the session detailed above) and determined by your Unit coordinator. Submissions made after the due date and time will be penalized per day late (including weekend days) according to Holmes Institute policies.
The SafeAssign similarity score will be used in determining the level, if any, of plagiarism. SafeAssign will check conference web-sites, Journal articles, the Web and your own class members submissions for plagiarism. You can see your SafeAssign similarity score (or match) when you submit your assignment to the appropriate drop-box. If this is a concern you will have a chance to change your assignment and resubmit. However, re-submission is only allowed prior to the submission due date and time. After the due date and time have elapsed your assignment will be graded as late. Submitted assignments that indicate a high level of plagiarism will be penalized according to the Holmes Academic Misconduct policy, there will be no exceptions.
