This book describes the standard Java interfaces that make portable object-oriented access to relational databases possible, and offers a robust model for writing applications that are easy to maintain. The second edition has been completely updated for JDBC 2.0, and includes reference listings for JDBC and the most important RMI classes. The book begins with a quick overview of SQL for developers who may be asked to handle a database for the first time, and goes on to explain how to issue database queries and updates through SQL and JDBC.
