Database Programming with Java

Standard relational data access is very important for Java programs because the Java applets by nature are not monolithic, all-consuming applications. Because applets by nature are modular, they need to read persistent data from data stores, process the data, and write data back to data stores for other applets process. Monolithic programs can afford to have their own proprietary schemes of data handling, but because Java applets or applications are cross operating system and network boundaries, you need published open data access schemes.

Java Database Connectivity (JDBC) is a part of the Java Enterprise APIs and provides cross-platform, cross-database access to databases from Java programs. The Enterprise APIs also consists of Remote Method Invocation (RMI) and serialization APIs (for Java programs to marshal objects across namespaces and invoke methods in remote objects), Java IDL (Interface Definition Language) for communicating with CORBA and other object-oriented systems, and Java JNDI (Java Naming and Directory Interface) for access to naming and directory services across the enterprise.
