So here’s my question: do you think I should release it? Could it actually do more good than harm? I’d really appreciate your honest opinion.
My first honest opinion would be the many engineers at Oracle could design something more efficient than a single person. But I'm typing this on a
bitcoin forum, so I know its happened before.
The military will use anything that gives them an edge but we can't stop moving forward out of fear, right? It's not like your new database format will change the world like the fusion bomb did. I would think most field applications in the military would not need a joinable database anyway. All the cross referencing and sneaky calculations would be run on army mainframes before the mission started - not under limited/restricted conditions.
Would you release it as open source like mySQL or as a managed service? Are you looking to be recognized as an inventor or do you want to make as much $ as possible? If you can give us more details of your future plans, we can help you with your choice in a more informed manner.
I’m aware that if I were to pass away...
You will never experience your death - not the entire thing, anyway.

I agree that Oracle obviously has endless advantages when considering different functionalities, but it's like perspective— for example, in the Roman Empire, there was an almost invincible wall, but it would only take an ancient army with a different perspective, like flight, to bring down the castle by having a completely different viewpoint. It might sound crazy, but it comes down to that. BoundDB is like looking at a different perspective than the one currently known for data storage. Anyway, I plan to publish the project soon. Although the documentation is sparse, if I see that the community is interested, I can start adding some layers that I will leave out for now.
