I'm sure there's a name for software of this kind, but Google hasn't been particularly helpful.
I'm looking for online, self-hosted software that will generate a database/spreadsheet table with columns of my own design. I want to make a searchable table of aircraft registrations and details of the aircraft and owners. If I need to design the DB tables beforehand and the software simply connects to it, that's also fine.
It would be great if I could link pictures to each record, perhaps after a user clicks on an aircraft in the list, the most recent pictures could be shown.
I'm looking for something more user-friendly than phpMyAdmin or other similar DB frontends, that can support multiple users, ideally on Linux.
