The above diagram is my work, now have to map it to relations. I'm not sure what the primary key for Matches is. But it can't be "Match Number"

Your task: Translate the ER diagram created in Task 2 to relations, represented by their schema. Make sure that you apply the correct translation strategies based on the type of relationships in the ER diagram. Separately list Foreign Key constraints. (6 marks) Notes: The abbreviated schema notation (see Assignment. 1), with underlined primary key attributes, will be sufficient for presenting the translated relations; - Produce separate relations for the superclass and subclasses if they are needed in the ER modeling; - Explanations should be provided for the foreign keys, if any, added to the translated relations
