i am trying to create a quite secure web-portal with a database backend. (mysql)
i was wondering if it is possible somehow to map the users that would be created to use the system, to "real" mysql users -- the idea was to have security from the backend:
the main "surfer" would connect to the db via a user that can only read all data.
system users would connect with their username (+level) so they have read and write access to several parts.
as far as i found out, users in mysql are only used for access_control, there is generally no information which user put which entries to the DB (please correct me, if i am wrong).
is there some way to restrict the DB-users to just be able to modify and delete content they added to the db (from the backend side)?
this would bring a really good access-by-level aproach:
-websurfers connect to the db with a user that can just read
-system users connect with their account, can write into some parts (tables) but can just delete/mod their own added content (or maybe group content)
