Please, i need help.

i wonder if rail allows to have 1 legacy database in informix and other  
mysql database (no legacy) in the same application.

I need to query in the informix database and manipulate data to save in  
mysql.

It is posible?? it it is, how? any guide? tutorial? link?

I’ll appreciate any help.

best regards.

Mary

Not tried it myself but there does appear to be a fair bit of  
documentation - eg  
[http://wiki.rubyonrails.org/rails/pages/HowtoUseMultipleDatabases](http://wiki.rubyonrails.org/rails/pages/HowtoUseMultipleDatabases)

(top of the list for a google search on “rails multiple databases”)

Also, someone’s kindly done a rails-informix adapter for you 🙂
