Disclaimer: I don't want to minimize your achievement or be overly critical of the tool you've built. I've used a lot of relational database modeling tools in the past and what you've built looks perfectly capable for the job. But I clicked on your link hoping for something very different and didn't find it. So hopefully others can point me in the right direction if what I am looking for exists.<p>The crux of my disappointment stems from you having left out a word in the description of your tool. It's a <i>Relational</i> Database Diagramming tool...the Relational aspect of it making it significantly less useful for me. I've worked with Relational databases for close to 30 years and I find that I'm able to design schemas in my head without the need for a tool. On occasion, a tool that's able to reverse engineer a visualization of the model from the schema can be useful in quickly coming up to speed on an existing schema, but even that isn't essential.<p>Where I think tools would really help me is in designing for non-relational databases. It's a harder problem, since those databases are often schemaless, but that would make a design tool all the more useful, since those designs could act as documentation that's often unnecessary in the relational world where the schema is readily available.<p>So can anyone point me towards a visual design tool for non-relational databases, document, kv or otherwise?
