Designing And Developing A Database For The 2018 Commonwealth Games Swimming Event

Data Requirements for the Commonwealth Games Swimming Event

The 2018 Commonwealth Games is an international multi-sport event for members ofthe Commonwealth that will be held on the Gold Coast between 4 and 15 April 2018.

The event has been called simply ‘Gold Coast 2018’ and has an abbreviation of GC2018. This will be the 21st Commonwealth Games which is held every four years. Over 6,600 athletes and team officials from 70 nations and territories will converge on the Gold Coast for the 11-day sporting and cultural event. Approximately 15,000 volunteers will help to make the event run smoothly and create a wonderful experience for everybody.

Swimming has always been a major event at every Commonwealth Games with Australia often leading the medal-count in the past. There is no doubt that in 2018, with the ‘home turf’ advantage, Australians will expect our swimmers to bring home gold! The Gold Coast Aquatic Centre has been fully redeveloped in preparation for GC2018.

The Centre has six pools, including a new 50 metre 10-lane competition pool, an 8-lane 50 metre pool, a full suite of diving facilities and a dry dive training pit. The final races will always be held in the 10-lane pool.

All events will be held in one of the two 50 metre pools and athletes will compete inevents 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 complete 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.

For a country to qualify and be included in the swimming events, there is no minimumnumber of team members, however each swimmer must qualify for their selected even (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.

Design and Development of the Relational Database

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 2017. 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.

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.

GC2018 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 GC2018 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 GC2018, your task is to develop a prototype database, and test it with queries which are likely to be used by GC2018. You are not required to write an application to use with this 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  Assignment 3 2017-S3 CSC00228 Database Systems  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.

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.

Queries and Results

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.

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.

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.

Choice and consistency of table and attribute naming conventions used, selection of data types, primary and foreign keys.

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.

Use of Views

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.

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.

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.

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.

The Federation would like to identify swimmers that have not qualified for the events they have registered in. Create a query that selects these swimmers only, showing the country, swimmer name, email address, contact number along with the Event Name, minimum qualifying time, the swimmer’s qualifying time and the difference between the times.

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.

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.

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.

Create a query that displays a list of events for which Rebekah Riley (or useanother name from your swimmer data) was registered and the races that theyswam in. Results should be sorted by event name, race name, date and time and provide all recorded swim times, places and whether they won any medals.

Create a query that displays each country with three calculated columns showing total number of swimmers and how many Gold, Silver and Bronze medals were won. Sort by number of Gold medals won.

Create a query to show a list of all team members who have coach or medical officer qualifications. Your query results should be sorted by the country, then the team member’s last name and first name. You must include the following:

• Country name;
• Team member’s last name, first name, phone number;
• Level of coach qualifications (if applicable) and date of certification;
• Medical Officer qualifications (if applicable), date of qualification, medical specialisation and insurance details.

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.
