Average Reviews:
(More customer reviews)For the past 2 years Wrox has been publishing books dedicated to Windows-based data access (ADO etc.), but the same cannot be said about their Java/database collection. Although you find chapters on JDBC scattered all-over almost all server-side Java related books by Wrox, there was no single volume from them that teaches JDBC first, and then show how it is used by the newer dependent technologies, until this book arrived. After looking through this book, I must say the authors and editors have done a rather commendable job.
Why do I make the above conclusion? Let me give you my general impression of the book first. A theme repeated in several of my recent reviews on books from Wrox is about the problem in coherence associated with multi-author books. Well, having more than a dozen of authors for a single book seems to be a fact of life (for books from Wrox at least) now, as the publication cycle gets shorter. I was rather surprised to find out that the organization and coherence is very good in this book, i.e., there is very little overlap among chapters. Also, this books uses JDBC cleverly to tie other pieces of J2EE together, making smooth transitions from one chapter to another. If you want to know, this factor alone prompted me to add an extra star to the overall rating of the book.
Let's now run down the chapters of this book quickly. The first 115 pages deals object-oriented and database modeling, and can be skipped by any "Professional" developer. Then after your obligatory intro to JDBC API, the next chapter covers the JDBC 2.0 optional package. This is the best treatment of this topic I have seen. Then another chapter is all about SQLJ, another first. The effort of having a chapter on database performance should be lauded, where connection pooling, prepared statements and stored procedures usage are demoed. The reminder of the book is about applying JDBC in various J2EE components, such as JSP, servlets, EJB, JMS, and XML. For this part of the book, even though I accept the fact the proper stage has to be set for each one of them, I still don't believe the book found the right balance between focusing on JDBC and showing what these other technologies are about. A large number of pages are used to teach basic JNDI, servlets, JSP's, and EJB's stuff (remember there is already a book on J2EE from Wrox!). Therefore, it is up to the reader to discover the real nuggets of gold hidden in this pile, which are far and in between in places. I found that some critical issues are not highlighted or details are lacking, such as how to use connection pooling/data sources in servlets, JSP's, and EJB's, the threading issues related to sharing database connections, and good database practices in BMP EJB's. However, the one thing I cannot complain about is that the book did not forget to teach the transaction aspect of EJB with a good depth (there is a short ans sweet chapter on using JTA/JTS inside EJB). There is also a chapter on the brand-new JDO framework, even though the spec is still in a state of flux. Finally, there are 4 case study chapters in the book - although the design and implementation are limited in scope and as a whole those samples do not teach all you need to do know about enterprise scale J2EE system development, they do provide a flavor of how JDBC is used in real world, together with setting up Tomcat, JRun, Orion, and WebLogic to access MS SQL Server and Oracle databases.
Now my overall take of this book. For VB/SQL and pure back-end PL/SQL developers who are eager to jump on the Java express train and need a suitable platform (especially for the ones who learn best from playing with actual code), I recommend this book as one of several you should own. Compared to other JDBC books from say O'Reilly and Sun's JDBC Tutorial, this book is the most up-to-date, contains the most source code, and has the broadest coverage of related topics. But keep in mind some of the advanced topics such as EJB and JMS can be intimidating for new-comers. On the other side of the coin, people who are advanced in various server-side Java technologies are unlikely to benefit a great deal from this book and should look elsewhere for info (for example Wrox's J2EE and upcoming EJB titles).

Java provides versatile technologies for data access and manipulation. This book investigates these technologies in detail and shows how they can be used to develop robust enterprise applications. The book is divided into five sections, the first of which looks at data and object modeling. The second section investigates accessing data in relational and object oriented databases, and directory services. The focus of the following section is data presentation for web clients. The fourth section covers Enterprise JavaBeans and distributed applications. The last section of the book consists of four real-world case studies that build on the previous chapters of the book. Transactions, performance, and scalability of data applications are also discussed throughout the book.
