Java Database Connectivity is a standard SQL database access interface, providing
uniform access to a wide range of relational databases. It also provides a
common base on which higher level tools and interfaces can be built. This
comes with an "ODBC Bridge". The Bridge is a library which
implements JDBC in terms of the ODBC standard C API.
