The first edition of this book appeared in 1991 when the technology was new and there were
not too many products. In the Preface to the first edition, we had quoted Michael Stonebraker …

Secure provenance techniques are essential in generating trustworthy provenance records,
where one is interested in protecting their integrity, confidentiality, and availability. In this …

Query optimization is the most critical phase in query processing. In this paper, we try to
describe synthetically the evolution of query optimization methods from uniprocessor …

Several scientific areas, such as bioinformatics and oil engineering, need means of
