Java 2.0 Standard Edition

Java DataBase Connectivity (JDBC)

A method of providing database interoperability similar to Open Database Connectivity (ODBC). This form of connectivity is Java specific, and other applications require a JDBC-ODBC bridge to provide the necessary interoperability between the two systems. JDBC always uses SQL statements to request data from the database manager. Although ODBC is language independent, it has limited platform support. JDBC is language specific but runs on any platform that supports Java.

Java Development Kit (JDK)

A special set of application development tools, resources, example code, help files, and other resources designed to help a programmer create Java applications. The JDK normally contains a full set of development tools and a copy of the Java Runtime Enviroment (JRE). However, most developers will require one or more third party solutions to create a complex Java application. For example, unlike many languages today, Java doesn't provide SOAP support, so the developer would require a third party library to create an application that relies on SOAP.

Java Runtime Environment (JRE)

Another name for the Java Virtual Machine (JVM). This set of files provides Java support on the host machine, allowing it to run Java applications.

Java Virtual Machine (JVM)

The application used to interpret the Java language originally developed by Sun Microsystems. This includes both text and byte code .CLASS files containing common routines. Java is similar to C++, but eliminates many of the complex programming constructs and uses a more restrictive security scheme. Many operating systems have a Java Virtual Machine including most versions of Windows, Mac OS, and Unix. The use of text files means that Java applets can run on any number of operating system platforms without modifications, but the use of an interpreter implies slower execution speed.
