The SQLJ standard for implementing embedded SQL in Java programs has been jointly authored and implemented by many leading DBMS vendors. This list of vendors includes IBM, Informix, Oracle, Sybase, and others. The standard allows programs to be vendor-independent, as long as the SQL-92 entry-level standard is used. This allows Java source code and binaries to be moved between platforms. As always, there are many exceptions to these rules, so always test the portability of your code before automatically assuming that this will work. This option does, however, provide database developers with a great alternative for developing applications over previously used proprietary database access languages.
