Database Design and Implementation

This textbook examines database systems from the viewpoint of a software developer. And what exactly is a database driver, anyway? The first two chapters provide a brief overview of database systems and their use. This textbook examines database systems from the viewpoint of a software developer. This perspective makes it possible to investigate why database systems are the way they are. It is of course important to be able to write queries, but it is equally important to know how they are processed. We e.g. don’t want to just use JDBC; we also want to know why the API contains the classes and methods that it does. We need a sense of how hard is it to write a disk cache or logging facility. And what exactly is a database driver, anyway? The first two chapters provide a brief overview of database systems and their use. Chapter 1 discusses the purpose and features of a database system and introduces the Derby and SimpleDB systems. Chapter 2 explains how to write a database application using Java. It presents the basics of JDBC, which is the fundamental API for Java programs that interact with a database. In turn, Chapters 3-11 examine the internals of a typical database engine.Each chapter covers a different database component, starting with the lowest level of abstraction (the disk and file manager) and ending with the highest (the JDBC client interface); further, the respective chapter explains the main issues concerning the component, and considers possible design decisions. As a result, the reader can see exactly what services each component provides and how it interacts with the other components in the system. By the end of this part, s/he will have witnessed the gradual development of a simple but completely functional system. The remaining four chapters then focus on efficient query processing, and focus on the sophisticated techniques and algorithms that can replace the simple design choices described earlier. Topics include indexing, sorting, intelligent buffer usage, and query optimization. This text is intended for upper-level undergraduate or beginning graduate courses in Computer Science. It assumes that the reader is comfortable with basic Java programming; advanced Java concepts (such as RMI and JDBC) are fully explained in the text. The respective chapters are complemented by “end-of-chapter readings” that discuss interesting ideas and research directions that went unmentioned in the text, and provide references to relevant web pages, research articles, reference manuals, and books. Conceptual and programming exercises are also included at the end of each chapter. Students can apply their conceptual knowledge by examining the SimpleDB (a simple but fully functional database system created by the author and provided online) code and modifying it.

This book takes software developers through database systems while covering the traditional database system concepts from a systems perspective. The chapters are organized according to the components of a database, starting from low–level disk access and ending at the query planner. A software developer’s hands–on guide to database systems Combining an eminently readable style with a practical approach, Edward Sciore’s Database Design and Implementation introduces you to database systems from a software developer’s perspective. In its pages, you will learn how to use a database and how to develop one of your own. Organized according to the components of a database, Database Design and Implementation takes you through database systems concepts from low–level disk access all the way to the query planner. Presenting only the essential algorithms and techniques that most clearly illustrate the issues discussed, the book covers such topics as data design and manipulation; integrity and security; memory and record management; metadata; query processing and optimization; integrity and security; indexing, and more. As you proceed through the chapters and numerous exercises, you’ll learn: How to build database applications in Java JDBC, JPA, XML, and Servlet development The internals of a database server Sophisticated techniques for indexing, sorting, intelligent buffer usage, and query optimization Best of all, this book includes a simple but fully functional database system, SimpleDB, that enables you to apply your conceptual knowledge by examining and modifying the code. With numerous hands–on exercises and such tools as SimpleDB, Database Design and Implementation will give the self–studier as well as the traditional student an ideal introduction to the world of database systems. ∗ Covering the traditional database system concepts from a systems perspective, this book addresses the functionality that database systems provide as well as what algorithms and design decisions will best implement their functionality ∗ Describes what Java tools and techniques will best help developers build an application that uses a database system ∗ Contains a fully functional database system that allows readers to examine and modify the code
