N:M relationships can have more than one entity on each side of the relationship, meaning that multiple entities from one table can be connected to multiple entities from another table. This is different from one-to-many relationships, which have a minimum cardinality of at least one entity on one side and potentially many entities on the other side. N:M relationships are also not the same as N:N relationships, which do not exist in relational databases as they do not conform to the rules of normalization.
