How to Lock Tables on the BackEnd .mdb file

RLN

RE: Access 2003

My users have an .MDE as their front end.
With this .mde they can still get to the container, double click a
table, and modify data on the back end.

What is the best way to lock the tables on the back end .mdb so they
cannot get to the data?

Upgrade the back end to SQL Server Express and apply security from there.
Use only stored procedures to retrieve, update and delete data.

The OP wanted to know how to prevent people from getting to the data.
Wouldn't running a stored proc that selected from the table be enough
to "get to the data"?
And for that matter, running the Update sproc be enough to alter that
data?

I meant to add: of course this assumes they have access to that data
in the first place. Maybe I misunderstood the OP's scenario.
OP, can you clarify: does the user have access to the data when using
the application?
(if the answer is Yes, I'm leaning towards RWOP queries)

If you read his earlier question, he's concerned with users changing the data
in the tables manually. It looks to me like he wants them to use only his
app to show, update and delete data.

He asked for the best way. Access user level security isn't in that category.

I anticipate there will be a need for changes in the other tables and since communication is over the internet, having the products table in a different file...

Hi All, I've got a situation where I am developing an Access 97 app for a client, and am in the "beta testing" stage. I have split the app up, using the DB splitter, into front-end /back-end for the usual reason ... so I can mess with form/report revisions. Since splitting, I've had issues with re-linking the tables ... as it relates to the completetely different "My Documents" data paths on several different Win98 / Win XP computers.

My front-end code manually links to the backend file. I was wondering what stops Access from linking to the system tables in the backend file. Is it just by virtue that they are hidden?

Access kept saying it couldn't find it. When I looked in the db...
