Why would I define the Default System Types Directory in Preferences?
If that directory has been defined you do not need to worry about domains etc. when upgrading Data Modeler. All the system type kind of things are automatically available even though you upgrade.Things like:
Report templates
Report configurations
Saved searches
Custom report templates
Domains
RDBMS Sites
Custom Scripts
Types
Global Design Level Settings
And you can also add this directory to version control to be able to keep track of the changes…

I love this article, your approach and thoughts. They are quite interesting and make me think in a different way.
Thanks for sharing awesome article!
Hi Heli,
It’s possible to use “Global Design Level Settings”, but with my personal settings?
Thanks.
Hi!
Design level settings are always for the design and for everybody who is using thet design. Preferences you can define only for yourself.
Best regards,
Heli
