There is no "Mendix DB (SQL)" :)
We support a range of databases (HSQLDB, MS SQL, mysql etc) as backends.
However, I think you mean that you want to import data from a non-mendix application into a mendix application? There are a number of possibilities:
- If the application supports it, you
can export the data as xml and
import it via an XML Import action.
- If the application has a webservice
interface, you can try to extract
the data that way.
- You can build a custom java action
and import an SQL dump line by
line.... But it'll probably take a
lot of work to set everything up
correctly.
Hope that gets you on your way.
