Introduction to Database Systems (set of 2 books)

The set consists of two volumes of the textbook by C. J. Date "Introduction to Database Systems". These books provide a comprehensive introduction to the field of scientific and technical knowledge, which has recently become extremely important. These books allow for solid training in the theoretical and practical foundations of database technology while also providing a certain understanding of how this area of activity will develop in the future. This edition has been supplemented and corrected in light of the latest trends and achievements in the field of database systems, but the reader is still given the opportunity to achieve a complete mastery and understanding of the material presented, rather than just familiarize themselves with a dry, formal description.
