1:N A one-to-many mandatory relationship is the most common relationship in databases. The primary key table contains only one record that relates to none, one, or many records in the related table. This relationship is similar to the one between you and one of your parents. You have one mother, but your mother may have several children.

N:1 A many-to-one is opposite of one to many (1:N) relationship.

1:1 In a one-to-one relationship, both tables are limited to one record only on either side of the relationship. Each primary key value relates to a single record, or no record, in the associated table. They are like spouses — you may be married, or not; however, if you are married, both you and your spouse can have only one partner. Most one-to-one relationships are forced by business rules. If you do not have a business rule, you can, in most cases, combine both tables into one table without breaking normalization rules. 0:N A zero to many optional relationship indicates that a person may have no phone, one phone, or many phones, and that the phone may not be "owned," but can only be owned by a maximum of one person.

N:0 Opposite of a zero to many relationship

0:1 A zero to one relationship might indicate that a person may be a programmer, but a programmer must be a person. It is assumed that the mandatory side of the relationship is the dominant.

1:0 Opposite of a zero to one relationship

N:N In a many to many relationship each record in both tables can relate to an unlimited number of records (or no records) in the other table. For example, if you have many siblings, your siblings also have many siblings. Many-to-many relationships must have a third table, referred to as an associate or linking table, because relational systems cannot accommodate the relationship directly.

THURSDAY, Oct. 10, 2019 (HealthDay News) -- Married folks not only live longer than singles, but the longevity gap between the two groups is growing, U.S. government health statisticians report. The age-adjusted death rate for the married declined by 7% between 2010 and 2017, according to a new study from the National Center for Health Statistics (NCHS), part of the U.S. Centers for Disease Control and Prevention. "Not only is the rate for married lower, but it's declining more than any other group," said lead author Sally Curtin, an NCHS statistician. Statistically, death rate is the annual number of deaths for every 100,000 people. It's adjusted so that a 26-year-old and an 80-year-old married or widowed or divorced are on equal footing. The new study reported that the death rate for never-marrieds declined only 2%, while that for divorced people hasn't changed at all. Worst off were the widowed, for whom the death rate rose 6%. They have the highest death rate of all the categories, researchers said.
