Q2 Draw a relational model for the following case study (9 marks) Case Study
The local under-sixteen football league needs a database to help track teams, children that sign up to play in the league, the parents of these children and the coaches for each team.
The league wishes to record the details for each parent of a particular player (the parents last name, first name, phone contact number and address). For each player, the system needs to record the player's last name, first name, blood type and their date of birth. Any allergies that the player has also need to be recorded.

A player may only play in one team with this league. Each team is given a unique id, the system needs to record this id, the teams name, and the city their home ground is located (a city may have several under-sixteen teams based in it). A team's colours are also to be recorded, teams may choose to use a single or multiple team colours. A team may have several coaches - one of the coaches is designated as the head coach.

A coach is only permitted to coach one team in the under-sixteen leagues. All communications from the league to the team are via the head coach. To be registered to play in this league a team must have a head coach and at least one player. The database needs to track a coach's first and last name, phone and address contact details and the team that they are coaching.

Q3 Convert the following table into Third Normal Form (3NF). Clearly mention each step of the process. You can make the appropriate assumptions and key(s) for your normalized tables.
