Hello,

I’ve developed an ActiveRecord adapter for MonetDB, and I would be  
glad if you people give it a try and give me some feedback and  
possibly join the project as developers/maintainers.

MonetDB is an open source high-performance database management system  
developed at the National Research Institute for Mathematics and  
Computer Science (CWI; Centrum voor Wiskunde en Informatica) in the  
Netherlands. It was designed to provide high performance on complex  
queries against large databases, e.g. combining tables with hundreds  
of columns and multi-million rows. As such, MonetDB can be used in  
application areas that because of performance issues are no-go areas  
for using traditional database technology in a real-time manner.  
MonetDB has been successfully applied in high-performance applications  
for data mining, OLAP, GIS, XML Query, text and multimedia retrieval.

More information on MonetDB can be found at :

You can get the database adapter at :

Thanks for your time,  
Michalis Polakis

This looks very interesting. I’ve been looking recently for a DB that  
could  
store XML documents ‘natively’ while allowing SQL queries on the data so  
I  
could get ActiveRecord functionality. I’ll definitely begin checking  
this  
out. Hope you won’t mind if I ping you off-list for some additional  
info.

Best regards,  
Bill

Bill,

I’ve been doing exactly that with DB2 Express-C and its pureXML  
functionality,  
which is free (as in beer).

It stores the data in XML column as parsed XML documents and you can use  
SQL,  
XQuery or combinations of these to access the data.

I’m doing a presentation (D.V.) on this at the Information on Demand  
conference in Las Vegas in October.
