In relational algebra terms, it removes the divisor from the dividend, leaving the difference. This type of query is the inverse of an inner join. Informally, it's called a find unmatched rows query.Set difference queries are great for locating out-of-place data or data that doesn't match...

I have studied about cartesian products of two tables in relational algebra which is used in order to derive such results. I am curious to know how cartesian product is related to these 'from' clauses. In the anticipation of reply. Thanks in advance. ...

We extend the well known duality between distributive lattices and Priestley spaces, in order to exhibit a relational Priestley-like duality for WHB-algebras. Finally, as an application of the duality, we build the tense extension of a WHB-algebra and we employ it as a tool for proving ...
