Re: module for XML databases

Oh, and +1 for the package, I'm indifferent in the XDB/XMLDB choice. :) Lux On Thursday, November 7, 2002, at 04:22 PM, Dave Viner wrote:

Here are my feelings on the subjects that have come up: Integration with RDBMS I think that XML databases are sufficiently different from relational dbs that integration with existing db abstractions would be difficult. And, I'm not sure it would buy a user a lot. Having a db class abstract Oracle vs. Mysql makes sense, since I can easily migrate my information from one to the other via SQL statements. But I don't think anyone would move from DB2 to Xindice or Tamino. The applications are simply too different, in my opinion. And the reasons for using a relational db are pretty different from the reasons for using an XML db. Naming Personally, I like XMLDB. I haven't seen XDB outside this discussion. Implementation Abstractions I think any PEAR class should aim to implement the XML:DB API. I realize not everyone abides by the api currently, but my understanding of the space is that the database maintainers are trying to migrate to that API. I think it would be very interesting to switch my xml db from xindice to tamino to berkeley db's xmldb without changing my PHP code. (Just as I can switch from Oracle to MySQL now.) As for the interfaces, I use http://sourceforge.net/projects/phpxindice/. The currently available release doesn't work to well, but I modified it to use PHP's internal xmlrpc implementation, and made it object-oriented. Also, I have my own xmlrpc server that handles a bunch of request types that are specific to my application. I've been meaning to clean up the code and contribute it to the project, but I haven't gotten around to it yet. dave -----Original Message----- From: Richard Samar [mailto:email@richard-samar.de] Sent: Thursday, November 07, 2002 12:26 PM To: pear-dev@lists.php.net; Dave Viner Subject: Re: [PEAR-DEV] module for XML databases Dave Viner wrote:

I've been using Xindice for several months... Xindice has a PHP administrative interface that I redesigned to be more fully functional.

I think a pear extension for it would be cool. dave

Could you let us know ...please :-) ...that an integration with abstraction layers of RDBMSs would make no sense? If you share my opinion. And where are these interfaces? I found some not really well documented things on sourceforge, but they didn't work for me. -moh -- PEAR Development Mailing List (http://pear.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PEAR Development Mailing List (http://pear.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
