Hi All,
Say we have two databases D1, D2, with the same number of entities and with equal functionality diagrams
(i.e., the functional dependence graphs are graph-isomorphic). Is there a notion in database under which D1, D2 are considered to be "the same" database , or some term equivalent to the same, as in the term "isomorphic" in Mathematics?
