This book summarizes the various semantic concurrency control techniques and deadlock handling techniques for object oriented distributed systems (OODS). It demonstrates how Object oriented concepts can be used to provide better concurrency and deadlock handling. It has the following chapters: - First chapter tells about the features and requirements of OODS - Second chapter gives the exhaustive survey of existing algorithms for concurrency control and deadlock handling techniques. - Third and Fourth chapter tells proposes concurrency control techniques for OODBMS. -Fifth chapter proposes a concurrency control technique for OODS. - Sixth chapter explores deadlock handling techniques for OODS. -Seventh chapter summarizes the results. The students and researchers interested in the areas of distributed objects, concurrency control, deadlock handling may find this book useful.
