Generating a DDL from a class diagram

[catriona]

Hi
I am new to generating DDLs from EA class diagrams and am experiencing an issue....

I am trying to generate SQL DDL for a single package of around 6 classes. I have followed the instructions in the manual but when it comes to generating the DDL it fails giving the error
"<Packagename>Database not defined."

I can't help feeling there is a really simple solution to this!

Hope someone can help.

Many thanks,
Catriona

I got the same error.
I have read all topic about DDL generation in the help file and found no clue there.
Can anybody help?
Thank you very much!
