| Abstract (English): | We study the possibility of obtaining functional dependencies from the scheme of the existing database, as well as the data contained in it. Statistical methods for finding dependencies between data were used to generate probability dependencies. Software implementation of the developed algorithm for generating dependencies provides connection to various data providers. Application testing showed that the correct results can be obtained with a sufficiently large amount of data in the source. [ABSTRACT FROM AUTHOR] |
| Abstract (Russian): | Приведены результаты исследования возможности получения функциональных зависимостей из схемы существующей базы, а также данных, содержащихся в ней. Для генерации вероятностных функциональных зависимостей использованы статистические методы поиска зависимостей между данными. Программная реализация разработанного алгоритма генерации зависимостей обеспечивает подключение к различным поставщикам данных. Тестирование приложения показало, что корректные результаты можно получить при достаточно большом объеме данных в источнике. [ABSTRACT FROM AUTHOR] |
