Tuple-generating dependency
text:
In relational database theory, a tuple-generating dependency (TGD) is a certain kind of constraint on a relational database. It is a subclass of the class of embedded dependencies (EDs). An algorithm known as the chase takes as input an instance that may or may not satisfy a set of TGDs and, if it terminates, outputs an instance that does satisfy the TGDs.
