Your original images stay were you put them, darktable won't move or change them. Metadata from the original files and metadata you add (tags, titles, etc, and editing information) are stored in the database (but *never* removed from the original files, those are not changed in any way). Images are never stored in the dt database. (There's a cache for thumbnails, in order to speed up operations, but those are not criticial, and you can remove them at any moment without loss of data). Metadata can also be stored in so-called sidecar files (xmp files that will contain the metadata and the editing operations you performed on the original image). You can recreate the image database from those xmp files. (dt has another database for e.g. styles and presets you can define, and some other general information). You can also use dt without the image database (see option "-library :memory:") but then you better use sidecar files, as that would be the only way to save edits between sessions. This also means that to get an edited image as a separate file, you need to explicitly export that edit to e.g. a jpg file.
