The study of relationship databases is a core component of virtually every undergraduate computer science degree course. This new edition of Theory and Practice of Relationship Databases retains all the features that made the previous edition such as success, and goes on to give even more comprehensive and informative coverage. Written in a tutorial style and containing a great many examples and exercises as well as extensively using illustrative and explanatory graphics, the author has produced an undergraduate textbook of great depth and clarity that is very easy to follow. The subject of relational databases is brought to life by the writing style and the inclusion of an homogenous case study that reinforces the issues dealt with in each chapter. The primary objective of the book is to present a comprehensive explanation of the process of development of database application systems within the framework of a set processing paradigm. Since the majority of these applications are built as relationship systems, a complete though reasonably concise account of that model is presented. Dr. Stanczyk has achieved this by concentrating on the issues that contribute significantly to the application development while de-emphasizing purely theoretical aspects of the subject. This has led to an imaginative and highly practical textbook that will be an excellent read for the undergraduate computer science student.
Fighting Warsaw is a human story. Stefan Korbonski, the leader of the Polish Underground State, portrays the years of the German occupation during the Second World War and the beginning of anti-Soviet underground activities thereafter. His story presents the entire organization, strategy, and tactics of the Polish underground, which included armed resistance, civil disobedience, sabotage, and boycotts. “...The Polish Underground was perhaps the best organized and most active of all wartime undergrounds; and Stefan Korbonski is well qualified to tell its story....He was, almost immediately after the fighting had stopped, arrested by the Russians...he managed to regain his freedom, and it is to this happy release that we owe this book, an absorbing account of Poland’s fight for freedom These are the highly personal memoirs of an active conspirator and, in their vivid detail and exciting anecdotes, they are probably more successful in conveying a sense of what the resistance was actually like than a more comprehensive treatment would be...Few people who read the author’s chapters on this one aspect of the resistance will fail to be moved by them or to come away from them with an increased understanding of the prerequisites of successful opposition to an occupying power that is both efficient and ruthless.”—GORDON CRAIG, New York Herald Tribune “...Fighting Warsaw...is one of the most absorbing, inspiring and ultimately disheartening documents to come out of the last war....The book, which is detailed and written with humor, modesty, and a surprising lack of rancor, makes it quite plain that there is an indomitable quality in the Poles that will prevent them from ever giving up their great dream....”—The New Yorker

This textbook provides a practical and comprehensive tutorial guide for understanding and implementing relational databases. Each concept, formula and operation is given a precise definition that covers both the form and meaning and, whenever appropriate, a behavioural description is given. To ensure that theory can be translated to practice, extensive examples are provided. The book is suitable for a first course in databases for undergraduates in computer science.
A guide to the relational database language SQL, which provides the form of the linguistic constructs and their meaning. Each operation is considered in terms of its purpose and syntactic definition, with semantic descriptions that refer to the relational algebra operations.
