One-way Relationship



/ˈwʌnˈweɪ riˈleɪʃənˌʃɪp/


A way in which two data entities or terms can relate where one rule is always true for another term but not vice versa.

For example: all squares are four sided shapes but all four sided shapes are not squares; all bratwursts are encased meats but not all encased meats are bratwursts. These one way relationships are written in the following way: “encased meat” → “bratwurst.” The concept is used in Endeca and in Logical Data Modeling.
