Is there any modeling tool for NoSQL database?

NoSQL database is often modeled differently than usual with relational databases. You can start by answering questions about how the data flow in the bank will be captured. So the important point for modeling your database should be: "What questions do I want to ask for my database?"

For example: 'Which cities have a state?' or 'How many inhabitants does each state have?'

After you have these questions, you need to create a template that answers these questions via BD NoSQL Cassandra. To model it you can use Creately which is an online tool for modeling banks.

DataStax maintains the DataStax DevCenter > , which is a tool exactly what you are looking for.

I have not found any free (or open-source ) solution for this feature.
