Java Database Connectivity

Abstract

Officially, JDBC is not an acronym; however, to all intents and purposes it stands for Java Data-Base Connectivity. This is the mechanism by which relational databases are access in Java. Java is an (almost) pure object-oriented language; however, although there are some object-oriented databases available, many database systems presently in commercial use are currently relational. It is therefore necessary for any object-oriented language which is to be used for commercial development to provide an interface to such databases. However, each database vendor provides its own proprietary (and different) API. In many cases they are little more than variations on a theme; however, they tend to be incompatible. This means that if you were to write a program that was designed to interface with one database system, it is unlikely that it would automatically work with another.
