https://doi.org/10.14308/ite000086Keywords:
comparison of tuple, relational database, relational divideAbstract
The article deals with questions concerning usage of modern DBMS, such as building queries with the "Great Divide" relational division. Various variants of relational division usage are described. The article contains description of the expressions relational based on algebra as well as examples in SQL language.
