Things like maintenance, website background, website title, favicon etc., where would it be best to store them? It would be single array of items. Do I just write it in flat CSV file, flat XML file, or use database for it (sounds pretty stupid to create single-row-table)?
(sorry for mess with tags, no idea how this question could be tagged)
