Hi Manu,

When I was studying the DB class, I read several of your posts on the 
French forum, which helped me.
I'd like to take this opportunity to thank you.
I also thank you for your suggestions and the code you provided.
I admit that I've only used collections to import data from csv files 
and I know very little about them.
I'll try to do what you suggest, but if I had to do what your code 
suggests, I'd use a class and the _compare() function.

Best regards
Gianluigi
