This remarkably comprehensive new book assembles concepts and results in relational databases theory previously scattered through journals, books, conference proceedings, and technical memoranda in one convenient source, and introduces pertinent new material not found elsewhere. The book is in- tended for a second course in databases, but is an excellent reference for researchers in the field.. The material covered includes relational algebra, functional dependencies, multivalued and join dependencies, normal forms, tableaux and the chase computation, representation theory, domain and tuple relational calculus, query modification, database semantics and null values, acyclic database schemes, template dependencies, and computed relations. The final chapter is a brief survey of query languages in existing relational systems. Each chapter contains numerous examples and exercises, along with bibliographic remarks.

Few languages are riddled with as many spelling inconsistencies and irregularities as English. Why is there such dissonance between the sounds of English and the spelling used to represent them? The answer lies in the history of the language itself. The History of English Spelling reveals the rich and complex history of Modern English spelling, tracing its origins and development from Old English up to the present day. The book provides a highly detailed, letter-by-letter analysis of the Old English basis of Modern English spelling, followed by in-depth coverage of the contributions from French, Latin, Greek, and the many other languages that have contributed to current orthography. Upward and Davidson also explore events in the socio-political history of England as an explanatory setting for developments in spelling, along with the works of a number of lexicographers (especially Johnson and Webster), and various proposals for spelling reform. The History of English Spelling reveals the richness of the complex and often frustrating alphabetic spelling system used in the English language.
