This textbook reveals the workings of numerous database systems, enabling readers to develop complex database applications. Students will gain hands-on experience by following the exercises. The theory is complemented by detailed examination of specific applications from a broad range of areas. The text assumes only basic discrete mathematics, linear algebra, and programming knowledge. Features: Provides descriptions of 11 types of databases, and 2 database systems; Concludes each chapter with bibliographic notes and exercises; Examines database design, including issues of database interoperability, data integration, interpolation and approximation, and prediction and data mining; Presents course aids at a supporting website; Covers topics on indexing methods, data visualization, the safety of queries, general evaluation algorithms, the efficient implementation of evaluation algorithms, and the complexity of the evaluation of different types of queries; Structured to allow for flexible course design.
Introduced forty years ago, relational databases proved unusually succe- ful and durable. However, relational database systems were not designed for modern applications and computers. As a result, specialized database systems now proliferate trying to capture various pieces of the database market. Database research is pulled into di?erent directions, and speci- ized database conferences are created. Yet the current chaos in databases is likely only temporary because every technology, including databases, becomes standardized over time. The history of databases shows periods of chaos followed by periods of dominant technologies. For example, in the early days of computing, users stored their data in text ?les in any format and organization they wanted. These early days were followed by information retrieval systems, which required some structure for text documents, such as a title, authors, and a publisher. The information retrieval systems were followed by database systems, whichaddedeven more structure to the data and made querying easier. In the late 1990s, the emergence of the Internet brought a period of relative chaos and interest in unstructured and "semistructured data" as it wasenvisionedthateverywebpagewouldbelikeapageinabook.However, with the growing maturity of the Internet, the interest in structured data was regained because the most popular websites are, in fact, based on databases. The question is not whether future data stores need structure but what structure they need.

From the reviews:
"Offers an introduction to modern databases. ... In this well-organized book, the presentation is simple and easy to understand. As a result, students will find this introductory textbook useful. Furthermore, they will benefit from its numerous illustrative examples, exercises, and bibliographic notes. ... The book offers an interesting perspective into the many specialized databases that are currently in existence--something virtually no other book on the market offers. ... In short, I strongly recommend it to readers who are interested in databases." (S. V. Nagaraj, ACM Computing Reviews, February, 2011)
"A book that covers all the modern turns and directions that databases have taken in recent years. ... Overall, this is a very valuable addition to the database textbook literature. The author claims that the primary audience for this book are undergraduates, but I believe that it can and will reach beyond that level of database education." (Gottfried Vossen,Zentralblatt MATH, Vol. 1191, 2010)
