Обсуждение: Object/relational mappers for PHP?
Hi gang, We finally have the underpinnings for database drivers in Joomla 1.5, and now are tackling the thorny issue of all those MySQL-specific SQL statements littering the core. One solution of course is to use Christopher Kings-Lynne's(sp?) MySQL compatibility goodies, but we are also looking to solve this riddle at the application layer so we can support more databases in the future. We have implemented some basic SQL generating methods in our database class (to manage LIMIT and LEFT JOIN differences, for example) but are primarily relying on ANSI SQL to get around most issues. I'd like to know if anyone here is already working on a class to generate SQL at the object level, as opposed to (re)inventing your own API to generate queries for each database engine. Anybody else working on something? -- Mitch Pirtle Joomla! Core Developer Open Source Matters

You may want to take a look at Metastorage. It is a code generation tool that generates Object-Relational mapping classes. It generates self contained code that does not need any runtime persistence framework. The generated code uses Metabase API to provide total database independence, not only at the database access level, but also at the database schema installation level. Among many other aspects it abstracts result row range SELECT (LIMIT clause), auto-incremented key access, etc.. It supports PostgreSQL among many other databases. You may find more information about Metastorage and Metabase here: http://www.metastorage.net/ http://www.phpclasses.org/metabase -- Regards, Manuel Lemos Metastorage - Data object relational mapping layer generator http://www.metastorage.net/ PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/
