Introduction to Database Systems. Volume 1

This book is a comprehensive introduction to the field of scientific and technical knowledge, which has recently gained exceptional importance. This book provides solid training in the theoretical and practical foundations of database technology and at the same time offers a certain understanding of how this area of activity will develop in the future. The current 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 full mastery and understanding of the material presented, rather than just familiarize themselves with a dry, formal description.
