For me personally, the book served its purpose of giving me a very good picture of how the Oracle database can be used by Java Applications using JDBC connectivity. When discussing with Java developers about Oracle, it is important to be familiar with the concepts of JDBC and how they can be implemented in Java. The book has helped me changing the perspective from the database administrators point of view to the java developers angle.
The author explains the 4 different types of JDBC Drivers, why it is a good idea to turn Autocommit off, etc. but perhaps the most basic but essential information given in the book is the distinction between the Statement and the PreparedStatement Interface and a clear recommendation to NOT use Statement class in production code. Moreover, the standard update batching as well as Oracle update batching is introduced with the recommendation to prefer the oracle implementation for performance reasons.
Apart from that, the more advanced features Statement Caching as well as Connection Pooling and Caching were of most interest to me. Although it did not make a java developer out of me, I could use the sample code to get familiar with the concepts. Other than that, the book is great as a reference to come back to different topics if need arises.
I can recommend this book to any Oracle database administrator, who wants to understand, how Java Applications use JDBC to interact with the database. On the other hand, it is a must-read for any Java Developer working with Oracle JDBC. Beware that this is not a book to learn Java, but specifically for understanding Oracle database interaction with JDBC.
