what is a one to one relationship in a database
One-to-one (data model) In a relational database, a one-to-one relationship exists when one row in a table may be linked with only one row in another table and vice versa. It is important to note that a one-to-one relationship is not a property of the data, but rather of the relationship itself. A list of mothers and their children may happen to describe mothers with only one child, in which case one row of the mothers table will refer to only one row of the children table and vice versa, but the relationship itself is not one-to-one, because mothers may have more than one child, thus forming a one-to-many relationship.
My One and Only (film) My One and Only is a 2009 comedy-drama film loosely based on a story about George Hamilton's early life on the road with his mother and brother, featuring anecdotes that Hamilton had told to producer Robert Kosberg and Merv Griffin.[3] Kosberg pitched the idea of this true story to screenwriter Charlie Peters, then Merv Griffin shepherded the project from screenplay to production, until his death in 2007. Merv Griffin's company served as one the film's producers and Robert Kosberg executive produced.[3]
