Vertabelo now supports Safari. It's marked as "beta support", but should be fully functional. In case of any bugs or other problems occuring under Safari, please report them in separate threads.
Enjoy Vertabelo in Safari!
Thanks for the compliments :)
Did you try to set the relevant connection property? I mean you can explicity set the database name to connect to. Just like this:
jdbc:sqlserver://192.168.0.5:1433;databaseName=my_database
We will check this. Thanks for reporting the issue.
Well, no one ever complained for such a behavior and we find it very helpful. I'll leave the topic open so that other people could express their opinion either by upvoting or in comments.
This is a desired behavior for great majority of our users. However, we'll discuss within our team giving an option to disable automatic creation of FK column. Thanks for sharing your thoughts.
No, you can share your model between users in the Free account plan. The only limitation is that you cannot accept an invitation to the model that exceeds your account plan limitations. In such case you'll need to switch your account to a paid account plan.
