The purpose of a Relationships
The purpose of a relationship is to link tables together by a specific filed that consists in both tables.
I linked the “Costumers Details” table with the “Lending Details” by the “Account no”. This is called a one too many relationships because there could be only one “Account no” in the “Costumers Details” table per costumer but in the “Lending Details” table the same person can take as many loans as they like. I linked the other two tables by the “Loan ID” this was also a one to many relationship because each loan in the “Loans Available” table can have only contain one “Loan ID” while the “Lending Details” table can have several; this is because many people may open the same type of loan which contains its ID number.
