What is the difference between share-level and user-level security?
Share-level and User-level security is actually in the category
of computers.
In share-Level security systems, passwords are associated with
specific objects, not with users.
ex. Windows XP
User-Level security is the most flexible and secure method of
protecting the sensitive data, code, and design of objects in an
Access database. User-Level security is for if you need more
control.
ex. To prevent users from modifying the design of your tables
and queries.
