Middlegen

Are you tired of the headaches involved with editing deployment descriptors and entity bean source code? Middlegen is a free general-purpose database-driven code generation engine based on JDBC, Velocity, Ant and XDoclet. If you already have a database, you can use Middlegen to generate.

• Persistance layer with EJB (CMP 2.0)
• Persistance layer with JDO
• Persistance layer with Hibernate
• Persistance layer with Torque
• Database GUI with JSP/Struts

Developping database-driven applications with Middlegen is easy:

1. Create the database with your preferred database modeler tool
2. Configure Middlegen to access the database and read the database schema
3. Run Middlegen from Ant, and (optional) with the GUI tool, rename tables and columns, tune relationships and type-mappings
4. Generate your source code with Middlegen
5. Run XDoclet to generate the additional files like EJB homes and interfaces, and deployment descriptors
6. Compile and deploy your application

eXist-db

eXist-db is an open source database management system built using XML technology. It stores XML data according to the XML data model and features efficient, index-based XQuery processing.

eXist-db supports many (web) technology standards making it an excellent platform for developing web based applications:

• XQuery 1.0 / XPath 2.0 / XSLT 1.0 (using Apache Xalan) or XSLT 2.0 (optional with Saxon)
• HTTP interfaces: REST, WebDAV, SOAP, XMLRPC, Atom Publishing Protocol
• XML database specific: XMLDB, XUpdate, XQuery update extensions (to be aligned with the new XQuery Update Facility 1.0)

The 1.4 version adds a new full text index based on Apache Lucene, a lightweight URL rewriting and MVC framework as well as support for XProc. Most important, the XQuery engine has seen a major redesign, resulting in improved performance.

eXist-db is highly compliant with the XQuery standard (current XQTS score is 99.4%). The query engine is extensible and features a large collection of XQuery Function Modules.

eXist-db provides a powerful environment for the development of web applications based on XQuery and related standards. Entire web applications can be written in XQuery, using XSLT, XHTML, CSS and Javascript (for AJAX functionality). XQuery server pages can be executed from the filesystem or stored in the database.
