Arguably the most capable of all the open source databases, PostgreSQL is an object-relational database management system first developed in 1977 by the University of California at Berkeley. In spite of its long history, this robust database suffers from a lack of easy-to-use documentation. Practical PostgreSQL fills that void with a fast-paced guide to installation, configuration, and usage. This comprehensive new volume shows you how to compile PostgreSQL from source, create a database, and configure PostgreSQL to accept client-server connections. It also covers the many advanced features, such as transactions, versioning, replication, and referential integrity that enable developers and DBAs to use PostgreSQL for serious business applications. The thorough introduction to PostgreSQL's PL/pgSQL programming language explains how you can use this very useful but under-documented feature to develop stored procedures and triggers. The book includes a complete command reference, and database administrators will appreciate the chapters on user management, database maintenance, and backup & recovery. With Practical PostgreSQL, you will discover quickly why this open source database is such a great open source alternative to proprietary products from Oracle, IBM, and Microsoft.

This concise book gives you the information you need to effectively use the Simple API for XML (SAX2), the dominant API for efficient XML processing with Java. With the SAX2 API, developers have access to the information in XML documents as they are read, without imposing major memory constraints or a large code footprint. SAX2 is often used by other APIs "under the covers", and provides a foundation for processing and creating both XML and non-XML information. While generally considered the most efficient approach to handling XML document parsing, SAX2 also carries a significant learning curve. In SAX2, author David Brownell explores the many details of managing XML parsers, filtering the information those parsers return, generating your own SAX2 events to convert non-XML information to an XML form, and developing strategies for using event-based parsing in a variety of application scenarios. Created in a public process by the XML-Dev mailing list, the SAX2 API is compact and highly functional. SAX2 uses callbacks to report the information in an XML document as the document is read, allowing you to create your own program structures around the content of documents. No intermediary model of an entire XML document is necessary, and the mapping from XML structures to Java structures and back is straightforward. Both developers learning about SAX2 for the first time and developers returning for reference and advanced material about SAX2 will find useful information in this book. Chapters provide detailed explanations and examples of many different aspects of SAX2 development, while appendices provide a reference to the API and an explanation of the relationships between the SAX2 API and the XML Information Set. While the core of the API is quite approachable, many of its more advanced features are both obscure and powerful. You can use SAX2 to filter, modify, and restructure information in layers of processing which make it easy to reuse generic tools. SAX2 also has some significant limitations that applications need to address in their own ways. This new book gives you the detail and examples required to use SAX2 to its full potential, taking advantage of its power while avoiding its limitations.

One of the most important challenges faced by Oracle database administrators and Oracle developers is the need to tune SQL statements so that they execute efficiently. Poorly tuned SQL statements are one of the leading causes of substandard database performance and poor response time. SQL statements that perform poorly result in frustration for users, and can even prevent a company from serving its customers in a timely manner. In this book, Mark Gurry shares his in-depth knowledge of Oracle's SQL statement optimizers. Mark's knowledge is the result of many hard-fought tuning battles during his many years of providing Oracle tuning services to clients. Mark provides insights into the workings of the rule-based optimizer that go well beyond what the rules tell you. Mark also provides solutions to many common problems that occur with both the rule-based and cost-based optimizers. In addition to the specific problem/solution scenarios for the optimizers, Mark provides a number of handy SQL tuning tips. He discusses the various optimizer hints, telling you when they can be used to good effect. Finally, Mark discusses the use of the DBMS_STATS package to manage database statistics, and the use of outlines to specify execution plans for SQL statements in third-party applications that you can't otherwise modify.

"This is a book that deserves a prominent place by anyone who aspires to be a real professional developer of SQL Server applications." --from the Foreword by Ron Soukup The message of this book is that building stored procedures in Transact-SQL is very much like building programs in any other language. It requires the same type of skill, planning, attention to detail, and overall grasp of technology that successful development in other languages requires. To master Transact-SQL, one must first master the fundamental concepts of software development, then build on this foundation by embracing and studying Transact-SQL as a programming language in its own right. This book teaches you how to do that and more. More than just a catalog of coding tricks and syntax subtleties, explores the philosophy of Transact-SQL programming. It teaches readers how to apply this philosophy in order to develop their own coding techniques and discover their own solutions to real-world programming problems. A follow-up to the widely acclaimed The Guru's Guide to SQL Server(TM) Stored Procedures, XML, and HTML The Guru's Guide to Transact-SQL, this book teaches that stored procedure development does not occur in a vacuum--it involves a wide variety of skills, subjects, and technologies--and helps the reader become a better software engineer, not just a stored procedure expert. Blending theoretical detail with practical application, this comprehensive reference begins with a foundational overview of SQL Server(TM) stored procedure programming. From there, the focus moves on to best practices and design considerations before progressing to advanced topics and a general philosophy of software craftsmanship. In all, this book provides the most complete coverage of SQL Server stored procedure programming available in one source. Topics such as user-defined functions, views, triggers, extended procedures, error handling, OLE Automation, database design, and XML are covered in detail. The book spotlights undocumented language features and brings the first application of design patterns to the SQL language. The preview of .NET and a groundbreaking approach to adding arrays to Transact-SQL make for the most thorough and engaging read published to date on SQL Server programming. The accompanying CD-ROM contains the book's source code. More than 700 SQL scripts, programming utilities, and extended procedures provide a veritable treasure trove of high-quality example code. Theoretically sound, yet immensely practical, provides developers with the tools they need to become expert stored procedure programmers and better software engineers.

This IBM Redbooks publication shows the different techniques customers can use to clone their DB2 system. Although the scenarios in the book use an SAP workload, the DB2 cloning techniques we describe are not specific to SAP. Those techniques can apply to any DB2 system and the applications running on that DB2. The book describes hands-on details of selected DB2 database cloning scenarios, typically the most popular techniques currently used by customers, as well as the most efficient scenarios we would like to recommend to DB2 database administrators. The scenarios described in this book are based on SAP examples. Our source system resides on a DB2 data sharing group. We have one target system residing on another DB2 data sharing group and one residing on a non-data sharing DB2. All source and target systems are in the same OS/390 Sysplex environment. We discuss and show DB2 system cloning techniques using the following methods: - ESS Flashcopy - DFSMS copy and rename The book addresses an audience with in depth knowledge of DB2 for z/OS and OS/390 database administration and savy in SAP system requirements.
