XML-DBMS is middleware for transferring data between XML documents and relational databases. It maps the XML document to the database according to an object-relational mapping in which element types are generally viewed as classes and attributes and PCDATA as properties of those classes. An XML-based mapping language allows the user to specify customize this mapping.XML-DBMS is available both as a set of Java packages and as a PERL module (courtesy of Nick Semenov (nsemenov@yahoo.com)). 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.

Tapping into the growing market for native XML database technology, ixiasoft has established itself as one of the leading suppliers. The TEXTXML server technology comes in a both industrial strength and a lite (lower cost/lower capacity) version. Given the technical difficulties of transforming XML documents into SQL databases a native XML database technology like TEXTXML has got to be a serious consideration when developing systems on top of XML repositories.

xmlGlobal's product line provides XML document transformation capabilities for existing systems. Support for ebXML and UDDI are provided in their three-layer architecture.

Apache Cocoon is an XML publishing framework that raises the usage of XML and XSLT technologies for server applications to a new level. Designed for performance and scalability around pipelined SAX processing, Cocoon offers a flexible environment based on a separation of concerns between content, logic, and style. Cocoon interacts with most data sources, including filesystems, RDBMS, LDAP, native XML databases, and network-based data sources. It adapts content delivery to the capabilities of different devices like HTML, WML, PDF, SVG, and RTF.

Igor is a 100% pure Java library that can be used to transform DB records into XML. The Igor project aims to enable developers to easily transform RDBMS records into XML. This software is being freely released under the LGPL license.
