In this assignment, you are a database analyst with the task to analyse a scenario, design, develop and test a database in MySQL using phpMyAdmin.
It is your job to analyse the data requirements provided in the scenario and design and develop a relational database to meet the client needs. You will also need to add data and create SQL queries to provide results suitable for reporting. This assignment intends to give experience in database design and development. It is based on a fictitious scenario. Your focus will be to:
- produce a fully normalised database design, modelled in an EERD, showing business rules;
- Develop entities (tables) with correct attributes included;
- Demonstrate supertypes and their associated subtypes;
- Demonstrate normalised relations;
- Make relational joins to ensure this prototype works;
- Produce evidence of correct working via database queries and screenshots of result sets.
Assignment 3 Part A – Enhanced Entity Relationship Diagram (10%)
Design and produce an Enhanced Entity Relationship Diagram (EERD) using a modelling or drawing tool. Present your assignment in a Word or PDF document using report template 3A. The report should include a title page, the EERD and business rule clarification (if necessary).
Assignment 3 Part B – Develop a Database Prototype (20%)
Build and test a database prototype based on your design in Part A. Submit a report documenting the end product using report template 3B and SQL script of your database.
The 2022 Commonwealth Games officially known as the XXII Commonwealth Games and commonly known as Birmingham 2022 is an international multi-sport event for members of the Commonwealth that will be held on the Birmingham between 28 July and 8 August 2022. This will be the 22nd Commonwealth Games which is held every four years. Over 5000 athletes and team officials from 72 nations and territories will converge on the Birmingham for the 12-day sporting and cultural event.
A new aquatics centre, scheduled to host the swimming and diving events, being built in Smethwick, is set to be completed in spring 2022. The facility will also include a 50m Olympic-sized swimming pool, as well as a 25m diving pool, community swimming pool and permanent seating for 1,000 people.
All events will be held in the 50 metre pool and athletes will compete in events for the four strokes – freestyle, breaststroke, backstroke and butterfly. The lengths for the races vary with 50m, 100m, 200m, 400m, 800m and 1500m races being held for freestyle, and at least 50, 100 and 200 metre races for other strokes. Most races have both Mens and Womens Division and there are also the relay team events and the medley which brings out the most versatile swimmers.
The Commonwealth Games Federation (CGF) provides a report outlining the requirements for swimmers to qualify to compete in the games. This includes the qualifying times which the swimmers must have equalled or bettered in an official competition event within the 12 months leading up to the games.
Qualifying Swim Teams
For a country to qualify and be included in the swimming events, there is no minimum number of team members, however each swimmer must qualify for their selected event(s). Each country’s team must have a team manager, team leader (typically the strongest swimmer) and at least one coach and one medical officer.
To apply for inclusion in the games, prospective countries must provide the Federation with the country’s swimming team details for consideration. All team members, including swimmers, coaches and medical officers, need to provide personal contact information.
The swimmers must provide their contact information, gender, date of birth and the name of their coach. For each race event they wish to compete in, they must provide the details of their qualifying time, the date and approved swimming competition where the time was recorded. The qualifying time must have been recorded in 2021.
Other team members:
All other team members must provide their contact information. Each coach also needs to provide details about whether they have qualifications and training as a coach. Coaches are required to have a police check for working with children (“WWC Check”). In addition, coaches are certified by the Federation, and must have the date of certification and level of certification (1 to 5) recorded by the Federation. Medical officers also need to provide details of their qualifications, including the year of their degree or latest qualification and any specialisations.
Preliminary Heats and Final Race
Several preliminary heats/races will be held to determine who will compete in the final race for each event. The result times for each swimmer completing in each of these races must be recorded. For each event, the final winner of the Gold, Silver and Bronze medals will be recorded.
Birmingham 2022 requires a database to store the data associated with all swimming teams, team members as well as the preliminary heats and final races held at the games. The system of spreadsheets and paper forms that Birmingham 2022 is currently using has many data inconsistencies that detract from their belief in the accuracy of the data and information provided. While keeping requirements for a new system closely aligned to the current manual system used by Birmingham 2022, your task is to develop a prototype database, and test it with queries which are likely to be used by Birmingham 2022. You are not required to write an application to use with this database.
The file DATA2001_Assignment3_SampleFormsWithData.docx, provided with this assignment, provides you with some sample forms and information. The file DATA2001_Assignment3_exampleData.xlsx will provide you with further details and some specific examples of the current manual system data to get you started. Note that this data is provided “as is” and is not transferable directly to tables in the new database.
The entities and attributes mentioned in the scenario and on the sample forms must be included. You will be required to normalise some of the above into smaller relations/tables prior to implementing your design into a database. You may add more attributes to help improve the design and efficiency of the database.
Part A – EERD – due Week 11
- EERD Drawing 7 marks
Using the scenario and the data requirements provided, you must analyse the data storage needs of the client. Identify all entities and attributes and the relationships between them. Using a drawing software tool (Visio, Lucidchart or similar – NOT Word), draw an Enhanced Entity Relationship Diagram (EERD) of your design using crows foot notation. Your EERD must show all entities, attributes, relationships and cardinality as well as any business rules identified. Supertypes and subtypes are also expected in the design.
- Database Design 3 marks
Your final design choices should allow you to create your relational database in fully normalised form. Following the normalisation process, you will determine the tables, primary keys, foreign keys and columns needed to provide all functionality required by the client as outlined in the scenario above. Identify your database schema using standard formatting for table names, keys, and foreign keys.
Deliverables: Your EERD diagram should be presented in a Word document using a basic report layout with a title page. The database schema should be included on a separate page. See “Submission Format” for document naming requirements.
Part B – Database Prototype – due Week 13
- Database Development 3 marks
Build your database in MySQL using PhpMyAdmin. Your database should be created on the Infotech server and be named with your username followed by Ass3 (eg: rmason 10Ass3). Referential integrity and any other constraints must be created, as required by your design.
- Database Design 3 marks
Choice and consistency of table and attribute naming conventions used, selection of data types, primary and foreign keys.
- Sample Data 2 marks
You must provide enough valid data in your database to run the SQL queries below successfully with at least 5-10 rows in the result set.
- Privileges 1 mark
Provide access to your database for the user eyuwono or another student user account of your choice. Details of how to do this can be seen in the provided screencast.
- Use of Views 1 mark
The database should be capable of producing the query results below. To get the required results, you may need to build underlying queries or views. Where appropriate, these views should incorporate the use of standard practical informative column headings that fit the expected use of the view.
- Export Script 1 mark
Once your database is finalised, you must create an export script (.sql) to create a backup of your database, including all database structures, table definitions and data. Name this SQL script as yourusernameAss3.sql eg: rmason10Ass3.sql.
- Proof of Testing 1 mark
The results of your queries should be presented in a Word document using a basic report layout with a title page, page numbers etc. The query that you create for each of the parts below should be pasted into your report (not screenshots), followed by a screenshot of your results. Snipping Tool on Windows is useful for taking screenshots of query results.
- SQL Queries:
Note: your result sets should not display any ‘extra’ columns – such as surrogate keys. Use surrogate keys in your progressive testing by all means, but your finished test results should not include surrogate keys unless specified in the question.
- Team Member list 0.5 mark
Create a team list for one of the countries. Results should be sorted by last name of the team member, and should include all contact details and team member type (e.g. Swimmer, Coach, Medical Officer or other contact type).
- Country swimmer count 1 mark
Create a query that counts the number of swimmers for each country. Results should have the country name, main contact name, the number of swimmers, and be sorted by the country name.
- Medical Officer information 0.5 marks
Create a query that displays a list of medical officers, with the name, email and phone number, country and any specialisations, sorted by specialisation then last name.
- Race information 2 marks
Create a query that displays the list of races scheduled for one particular event. Races should be sorted by heat number, and display the event name, race name, starting time and location.
- Event Winner list 2 marks
Create a query to display the list of winners for each event, showing event name, swimmer name and recorded times for the Gold, Silver and Bronze winners, sorted by event name and by winning place.
- Qualification check-list 2 mark
The Federation would like to confirm that all coaches were certified no more than 3 years ago. Create a query to show a list of these coaches, with their country, coach name, contact details and date of last training.
You must use Microsoft Visio, Lucidchart or similar modelling/design tool to create your EERD in Part A. There are a number of open-source/free tools such as Lucidchart and DIA available which are acceptable. You are required to use phpMyAdmin on the Infotech server to create your MySQL database in Part B.
Marking criteria will be made available via a rubric on the MySCU website.
You will be required to submit your assignment document via the MySCU site for this unit. Your assignment submission should be in the form of a Word document and a SQL script text file. Your Word documents should be named as username_Ass3A.doc (or .docx) and username_Ass3B.doc (or .docx). Your SQL script should be named as usernameAss3.sql
This assignment must be your own original work. Assignments form a major part of course work. Exchange of ideas with other people can be considered educationally valuable; however, excessive collaboration will be regarded as plagiarism, which is a University offence. For example, the copying of significant parts of a document (or database), even if subsequently modified, is plagiarism. Such academic dishonesty will be penalised in accordance with the University’s rules and regulations.
You must not copy material from books, magazines, internet sources or other students’ assignments. Of course, you may include direct quotes from any source, but these must be small (e.g. one sentence or one paragraph) and must be properly referenced, using the Harvard Referencing Style. The value and relevance of including materials from another source must be fully explained. If plagiarism is found in your assignment, you may receive zero marks for this assignment.
The assessment process may require some students to attend an interview in order to explain aspects of their assignment.
Retain duplicate copy
You are strongly advised to retain a copy of your original work and progressive versions of your work during the Session. In the event of any uncertainty regarding assessment items, you may be requested to reproduce a final copy and/or any previous versions of your work.
Penalty for late submission
A penalty of 5% per calendar day will be applied to all late assignments. An extension of time will only be considered (not necessarily approved) when a written request is submitted with appropriate supporting documentation and in accordance with University guidelines.
Marks and Feedback
Marks and feedback comments will be returned through your MySCU site for this unit.
