Answer to Question 1
Maximum cardinality describes the maximum number of instances in a given entity class that are allowed to participate in a relationship with a single instance of another entity class. Maximum cardinality is typically represented as being either 1:1 (one-to-one), 1:N (one-to-many), N:1 (many-to-one), or M:N (many-to-many). There is no restriction to only these common values, however, and other maximum cardinalities, such as 1:5 (one-to-five), are allowed.
