Data model development and implementation
|
Purpose of the assessment (with ULO Mapping)
|
The purpose of this assignment is to develop data models and map Database System into a standard development environment to gain understanding of data model development. Then implement the data model using a commercially available database management system development tool.
On completion of this assignment students will be able to:
a. Understand the fundamental principles of the networking and data requirements of a network.
b. Identify organisational information requirements.
c. Model organisational information requirements using conceptual data modelling techniques.
d. Convert the conceptual data models into relational data models and verify their structural characteristics with normalisation techniques.
e. Implement and utilise a relational database using a database system.

Submission Guidelines
|
· All work must be submitted on Moodle by the due date. Write your answers in this document underneath the question and save, file name should be:
“MN405_T3_2018_Assigment2_your_name.docx”.
· The assignment must be in MS Word format, 1.5 spacing, 11-pt Calibri (Body) font and 2.5 cm margins on all four sides of your page with appropriate section headings.
· Reference sources must be cited in the text of the report, and listed appropriately at the end in a reference list using IEEE referencing style.

Academic Misconduct
|
· Academic Misconduct is a serious offence. Depending on the seriousness of the case, penalties can vary from a written warning or zero marks to exclusion from the course or rescinding the degree. Students should make themselves familiar with the full policy and procedure available at:

Assignment Description
60 Marks
Questions:
1. Complete the information-level design for a database that satisfies the following constraints and user view requirements. In order to complete this information–level design you are required to answer the questions given below 1(a) – (f).
The local city youth league needs a database system to help track children who sign up to play soccer. Data needs to be kept on each team, the children who will play in each team, and their parents. Also, data needs to be kept on the coaches for each team and matches.
You need to store Team ID number and Team name of each team and Player ID number, Player first name, last name, and Player age of all players. Team may or may not have a Player. A Player must have a Team and should belong to only a one team.
You also need to store Coach ID number, Coach first name, Coach last name, and Coach home phone number. A Team may have many Coaches or may not have a Coach. A Coach must have only one team assigned to him / her.
For each parent, the Parent’s ID number, last name, first name, Home phone number, and Home address are kept in the system. A Player may have many Parents. A Parent may have only one Player.
Teams play matches. For each match we need to keep track of the following:
Ø Match ID
Ø The date on which the game is played
Ø The final result of the match
Ø Host team ID (HID) and Guest team ID (GID)
Write down any assumptions you make, if they are not explicitly described here.
a. Identify and list entities described in all user requirements given above.
(5 Marks)
b. Add attributes to these entities and represent them as a collection of tables and attributes (Database schema): e.g. Team (Team ID_Num, Team name,..)
Note: Select and underline suitable primary key for each table.
(5 Marks)
c. Outline 3 business rules that describe the relationships between entities.
(5 Marks)
Note:
You can make assumptions to create certain relationships, if it is not specifically mentioned in the given business rules.
e.g. A Player may have many Parents.
d. Determine the functional dependences.
(5 Marks)
e.g. Team ID number à Team names
e. Then normalise these tables. Make the normalization to
3NF. State for every step in the normalization, which functional dependency causes it.
(5 Marks)
2. Represent
the structure of your database
visually by using an entity-relationship (E-R) diagram. If you make any assumptions about data that are not explicitly given in the problem, these must be described.
Note: You need to use Visio, draw.io[1] or Lucid chart [2] or any other software tool, to create the ER diagram.
(15 Marks)
3.
Build
this model using
MS Access/ SQLite
by creating these tables and Relationships. Populate these tables with appropriate data; include at least 2 records in each table. Include the following in your MS Word document.
(10 Marks)
I. If you are using
MS Access
include following screen shots
§ Relationship diagram created in Access. (Select database tools àRelationships in the Access menu)
§ Data sheet view and design view of your tables.
Figure 1 Datasheet view
II.
If you are using
SQLite
· Screen shots of CREATE TABLE command and INSERT INTO commands.
Figure 3 CREATE TABLE command in SQLite
4.
Report Generation
a.
Write an SQL query
to generate one example of useful information that can be obtained from this database.
(5 Marks)
b. For additional 5 marks you can execute more queries (at least 2) on the database you created in Question 3 and include the screen shots of the outputs and all SQL statements.
(5 Marks)
