Enhydra DODS (Data Object Design Studio) is an open source O/R mapping tool with a difference.
XML data model descriptions (DOML files) SQL DDL, sophisticated Java O/R code and documentation (HTML, pdf, XMI) is generated automatically using a generator
Tutorial Details:
The generated Java code provides a lot of possibilities for runtime optimization (DO LRU caching, Query LRU caching, cache initialization, lazyloading,...)
DODS is completely reworked. Code generation is completely based on XML/XSLT (Ejen) and DODS generated code can now be used completely without the Enhydra application server ! The generated Java code now uses a very sophisticated LRU caching for DO\'s and Query results, supports multiple databases, transaction isloation/integrity and DO security callbacks. Documentation can be generated in HTML, PDF and XMI (UML in XML). The generator itself is now becoming a framework to support different code template sets. The generated SQL DDL can be split into separate files for tables, indexes, primary and foreign keys. Multicolumn indexes can now be defined in the doml.
