Doesn&#x27;t Lightroom use a MySQL database to store the users metadata&#x2F;tags?<p>Windows Vista&#x2F;7 Photo Gallery did the right thing, it stored the users metadata in the pictures (EXIF, XMP, etc metadata formats) inside the JPEG&#x2F;etc formarts. Windows Media Player stored the song user rating in the MP3 files in their ID3 tags too. iTunes does the contrary, stores everything in a SQLite db.
