Congratulations, ES, on a more unusual moniker, one that causes the person to think, in the words of G'kar, Babylon 5, "No one here is exactly what he appears. Not Mollari, not Delenn, not Sinclair .. and not me." Again, congratulations on an unusual entrance!
That being said, and due welcome offered, what's this software you're thinking about? Open source? Java based to run in a browser or platform-specific, aka Windows app? Most such will need some sort of database behind them in order to accumulate changes and history, AI, for example is written around an Access database core. SQL seems to have various flavors so that might be another way to go.
Keep us in the loop.
Best,
