Like others, not entirely sure what you mean here. May all-purpose "DB" or info store is OneNote, but I am making an effort to move as much as possible to TiddlyWiki this coming year. TW is relatively future-proof, as it's just a single HTML file that encapsulates all of the content and app in a single file that can be moved anywhere or used in any browser, but it gives you powerful structuring, storage, and linking capabilities inside it. (I almost never use flat text files for reference any more except for the simplest things, or if a machine needs to read it...) It gives you the best of what your filesystem can do for you (and filesystems are DBs, especially these days) combined with browser/wiki capabilities, and you can even hack the JS if you're into that sort of thing. My perfect solution would munge together the capabilities of TiddlyWiki and Jupyter notebooks into one awesome live, flexible, portable, programmable metacontainer. (I started on this with the first version of TW 20 years ago, combining test programs, data, and analysis/viz tools for sensor data collection into what I called "testacles" - test data receptacles capturing everything about a real-world test with IoT data, setup, docs, notes, code, data, etc. (I was building the world's first embedded IoT sensors at the time...)) BTW, thinking of adding BOOX's new Tab Ultra into my workflow - I've used pen on various Surface Pros for the last eight years (how OneNote became my go-to), but like the idea of not worrying about battery life. The Tab Ultra can run Android apps and a browser, so I should be able to use TW even if it's own pen note capture is too proprietary to be useful outside the device... we'll see.
