I have a bunch of data currently sitting in an Excel spreadsheet, however it's not really the best place for it. A database of sorts would be more suitable.
I'm aware Microsoft Access will do what I want, but I'm slowly moving away from Microsoft Office products (because, you know, a word processor etc... doesn't need to be "cloud connected"). Decades ago I used Q&A under DOS (see screenshot below) which is basically what I want today, but just to run on a modern (Windows 7) system and perhaps later on Linux once I move away from Windows. It will only ever be used to store text-based data (no images or other embedded content) and do some basic look-ups etc...
I suppose I could just use OpenOffice or LibreOffice, but just in case anyone has any other suggestions, I'm open to ideas.
