need help for database question

Question 17: A manager of a video game rental store has provided you with his requirements for a database as given below. Based on his requirements, identify the business rules that will be used to develop the data model for the database. Define the type of relationship described by the business rule. "The video game store has many genres of games such as role-playing games, strategy games, educational games and many more. However, because the store is small, there is only one copy of each game. A customer can rent as many games as he or she wishes. Again, because the store is not large, there will only be one employee managing the store at a given time."
