XML-DBMS

XML-DBMS is Open Source middleware for transferring data between XML documents and relational databases. It is used in a variety of settings, from universities to Fortune 500 companies to government agencies.

XML-DBMS maps the XML document to the database according to an object-relational mapping in which complex element types are generally viewed as classes (and mapped to tables) and attributes and simple element types as properties of those classes (and mapped to columns). An XML-based mapping language allows the user to customize this mapping.

XML-DBMS is available both as a set of Java packages (versions 1.x and 2.0) and a PERL module (version 1.x only). XML-DBMS, along with its source code, is freely available for use in both commercial and non-commercial settings. It is not copyrighted and has absolutely no warranty. Use it as you will.
