I have been tasked to create 

• ERD
• Logical ERD

For the ERD, it s my understanding that it doesn't need to have attributes, just table names and relationships, with dotted cardinality. 
- Is it possible to create square boxes with entity names without any attributes?

- Is it possible to show the cardinality with dotted lines?

- My guess is that Vertabelo shows "FULL ERD" with all attributes, but is it possible to show a simplified version showing only the entity tables -- I am not sure what type of UML this is called.

Thank you

Is there a way to undo an import?

Currenlty when i enter json or jsonb in the column data type, it throws unsupported data type error.

Does vertabelo supports json or jsonb data types?

I am not able to delete the models after the fee trail has expires. I want to subscribe to 1 member license and its not allowing me to delete extra models

Vertabelo does not appear to support the AWS Redshift SUPER data type (see https://docs.aws.amazon.com/redshift/latest/dg/query-super.html#dynamic-typing-lax-processing). The SUPER data type is not offered in the type dialog in the Table Properties pane, and if you try to import an SQL file with instances of the SUPER data type, it causes the import to fail.

Please add support for the AWS Redshift SUPER data type.

When creating our databases with thousands of fields we use domains / user data types. This allows us to use a specific defined data type, like "ID Key" for all primary keys, to ensure they are all uniformly the same data type. Additionally it would allow us to change the data types of all the fields that would apply without having to go to each field manually and changing it. This is a must for us to purchase a database modeling product.

it's a good tools but, the only issue is that it's fully online. can you make a desktop offline version ?

Could you please evaluate to allow export and import logical and physical data model via csv?

When we design a data model we map all the entities and attributes using Excel (specially for LOGICAL model), in vertabelo the only option to import logical and physical is using xml file.
