Re: XML language for database schema definitions

Hello, on 04/27/2005 10:04 AM Nsk said the following:

I am developing a PHP-implemented library which would allow a PHP programmer to write pre-defined data to a database. The library would be able to work with different database schemas and I need a way to "inform" the library with what kind of database schema it has to work with. I thought a good way to do that would be to describe the database schemas in XML. Because I don't want to write a new DTD just for this application, do you have any idea whether a database schema definition DTD already exists which allows XML documents to describe how a database is structured?

That is an old idea introduced by Metabase in 1999: http://www.phpclasses.org/metabase -- Regards, Manuel Lemos PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ PHP Reviews - Reviews of PHP books and other products http://www.phpclasses.org/reviews/ Metastorage - Data object relational mapping layer generator http://www.meta-language.net/metastorage.html
