Databases

a relational normal form in which every join dependency is implied by candidate keys, so a relation cannot be split losslessly any further.

In databases, project-join normal form refers to a relational normal form in which every join dependency is implied by candidate keys, so a relation cannot be split losslessly any further. This meaning comes from Fagin (1979) in Proceedings of the 1979 ACM SIGMOD international conference on Management of data - SIGMOD '79.[1]
