I think I use SQLite like that (to some extent):

For UI I use HTML, because it already provides components with bootrap, and everybody can use it without installation of any software.

All data comes from a single SQLite that is easy read, and returns data.

My database is really big, so it takes time to browse it, I wanted to provide more meaningful way to limit scope of searching
