Column copy and paste is already done. We've forgot resolve the issue here. 

To copy columns please do following steps:

- Select column by clicking dotted area near column name (left side, see attached screenshot). You can select more than one column using CTRL key.

- Press CTRL + C to copy columns to clipboard.

- Press CTRL + V to paste columns.

- Columns from clipboard should appear at the end of the column list.

You can also cut selected columns by pressing CTRL + X.

We fixed our today's infrastructure problems and our services should be fully operational. You should be able to log in using google authentication. 

There is also possible to log in via other auth mechnism (twitter, fb, github and Vertabelo Academy itself) and access to the same Academy account. To do this you should choose the same email address as you used with google auth, but it is important that you have to confirm that this is the same account by log in by original method first.

Hi Mark,

We are facing some problems with google authentication. It affects more users. We are investigating this issue now. I'll inform you when this type of authentication will be operational again.

There is no such type of reference in Vertabelo. Please notice that Vertabelo works on physical database model. ISA reference is usually related to conceptual database modeling.

To model inheritance in your database you can use plain references with techniques described here:

Thank you for asking this. Currently Redshift support isn't on our roadmap.

However Redshift is based on Postgres so you should be able to work without direct Redshift support. We covered this topic here:

I remain the idea opened so other users can upvote it.
