Hi all, For info : DBIx::DataModel v1.04 has been released to CPAN. This is a major revision from previous v0.35, with several architectural changes and added functionalities.
DBIx::DataModel is an Object-Relational mapping layer (ORM). Some of its strong points are : - UML-style declaration of relationships (instead of 'has_many', 'belongs_to', etc.) - efficiency through fine control of collaboration with the DBI layer (prepare/execute, fetch into reusable memory location, etc.) - improved API for SQL::Abstract (named parameters, simplified 'orderBy') - clear conceptual distinction between - data sources (tables and views), - database statements (stateful objects representing stepwise building of an SQL query and stepwise retrieval of results), - data rows (lightweight hashrefs containing nothing but column names and values) - joins with simple syntax and possible override of default INNER JOIN/LEFT JOIN properties; instances of joins multiply inherit from their member tables - named placeholders at the ORM level - nested, cross-database transactions The synopsis is in http://search.cpan.org/dist/DBIx-DataModel/lib/DBIx/DataModel.pm; the design principles and general architecture are explained in http://search.cpan.org/dist/DBIx-DataModel/lib/DBIx/DataModel/Doc/Design .pod Enjoy, Laurent Dami _______________________________________________ List: Catalyst@lists.scsys.co.uk Listinfo: http://lists.scsys.co.uk/cgi-bin/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.scsys.co.uk/ Dev site: http://dev.catalyst.perl.org/
