The JDBCTM API provides universal data access from the JavaTM programming language. Using the JDBC 3.0 API, you can access virtually any data source, from relational databases to spreadsheets and flat files. JDBC technology also provides a common base on which tools and alternate interfaces can be built.
The JDBC 3.0 API is comprised of two packages: the java.sql package
the javax.sql package, which adds server-side capabilities
You automatically get both packages when you download the JavaTM 2 Platform, Standard Edition, Version 1.4 (J2SETM).
