Book Description
The topic of using views to answer queries has been popular for a few decades now, as it cuts across domains such as query optimization, information integration, data warehousing, website design and, recently, database-as-a-service and data placement in cloud systems. This book assembles foundational work on answering queries using views in a self-contained manner, with an effort to choose material that constitutes the backbone of the research. It presents efficient algorithms and covers the following problems: query containment; rewriting queries using views in various logical languages; equivalent rewritings and maximally contained rewritings; and computing certain answers in the data-integration and data-exchange settings. Query languages that are considered are fragments of SQL, in particular select-project-join queries, also called conjunctive queries (with or without arithmetic comparisons or negation), and aggregate SQL queries. This second edition includes two new chapters that refer to tree-like data and respective query languages. Chapter 8 presents the data model for XML documents and the XPath query language, and Chapter 9 provides a theoretical presentation of tree-like data model and query language where the tuples of a relation share a tree-structured schema for that relation and the query language is a dialect of SQL with evaluation techniques appropriately modified to fit the richer schema.

Book Description
This work explores for the first time comprehensively the diversity and endemism of subterranean copepod crustaceans from the genus Diacyclops in the Far East. Previous scarce records have indicated presence of only a few widely distributed species, despite relative isolation of subterranean habitats in this part of the world and very dynamic changes in topography during the Pleistocene glacial cycles. A wide range of samples from Korea and Japan are studied, and all previous records of subterranean Diacyclops are re-evaluated. Morphological analyses of microcharacters, many of which are used in cyclopoid taxonomy for the first time herein, reveal high diversity in both countries. No subterranean species is found in common, although the existence of four sibling species pairs is probably indicative of relatively recent speciation. Seven species are described as new to science and two are re-described. This research provides evidence for the importance of subterranean habitats as reservoirs of biodiversity, and also demonstrates the inadequacy of current morphological methods for identifying closely related species of copepods. The disproportionately high diversity and short-range endemism discovered around Lake Biwa provides further evidence for the role of ancient lakes as biodiversity pumps for subterranean habitats.
