Transactions are a concept related to the logical database as seen from the perspective of database application programmers: a transaction is a sequence of database actions that is to be executed as an atomic unit of work. The processing of transactions on databases is a well- established area with many of its foundations having already been laid in the late 1970s and early 1980s.The unique feature of this textbook is that it bridges the gap between the theory of transactions on the logical database and the implementation of the related actions on the underlying physical database. The authors relate the logical database, which is composed of a dynamically changing set of data items with unique keys, and the underlying physical database with a set of fixed-size data and index pages on disk. Their treatment of transaction processing builds on the “do-redo-undo” recovery paradigm, and all methods and algorithms presented are carefully designed to be compatible with this paradigm as well as with write-ahead logging, steal-and-no-force buffering, and fine-grained concurrency control.Chapters 1 to 6 address the basics needed to fully appreciate transaction processing on a centralized database system within the context of our transaction model, covering topics like ACID properties, database integrity, buffering, rollbacks, isolation, and the interplay of logical locks and physical latches. Chapters 7 and 8 present advanced features including deadlock-free algorithms for reading, inserting and deleting tuples, while the remaining chapters cover additional advanced topics extending on the preceding foundational chapters, including multi-granular locking, bulk actions, versioning, distributed updates, and write-intensive transactions.This book is primarily intended as a text for advanced undergraduate or graduate courses on database management in general or transaction processing in particular.

The entire work Parsing Theory appears in two volumes, "Volume I: Languages and Parsing" and "Volume II: LR(k) and LL(k) Parsing". The two volumes form an integral work. Volume I is an introduction to the basic concepts of languages and parsing, and it also contains the relevant mathematical and computer scientific background needed in the development of the theory of deterministic parsing; it deals with topics such as algorithms on relations and graphs, regular languages and lexical analysis, context-free languages, left parsers and right parsers, strong LL(k) parsers and their implementation, simple precedence parsers. Volume II contains a thorough treatment of the theory of LR(k) and LL(k) parsing. "Parsing Theory" is a contemporary reference work on the theory of deterministic parsing of context-free languages. It emphasizes the LR(k) and LL(k) methods, which are developed in a uniform manner and pays special attention to their efficient implementation. Construction algorithms for parsers are derived from general graph-theoretic methods. Complexity questions about parsable grammars are analyzed.The work can be used as a textbook for graduate-level and senior undergraduate-level courses on parsing theory and compiler design. A one-semester course on the basic theory of languages and parsing can be taught from Volume I.

This is the second volume of a two-volume set representing an up-to-date reference work on the theory of deterministic parsing of context-free grammars. Volume I is an introduction to the basic concepts of formal language theory and context-free parsing. Volume II contains a thorough treatment of the theory of the two most important deterministic parsing methods. The two volumes together form an integrated work with chapters, theorems, lemmas, etc. numbered consecutively. The emphasis is on LR(k) and LL(k) methods, and special attention is paid to the efficient implementation of LR(k) and LL(k) parsers. Construction algorithms for parsers are derived from general graph-theoretic methods. Complexity questions about parsable grammars are analysed. The work can be used as a textbook in graduate and senior undergraduate courses on parsing theory and compiler design.
