hi guys, what are parent row, child row, parent table, child table, in relational database?

a parent row is a row in the parent table

a child row is a row in the child table

there, that takes care of two of them

"parent" and "child" are informal terms applied to two tables which have a foreign key relationship

the foreign key is defined in the child table, and refers to a primary or unique key in the parent table

the relationship is one-to-many -- each parent row can have multiple child rows, but each child row can have only one parent row


now all you need to look up is foreign key
