Control Data Display By User Group
Posted on 2012-12-28
Greetings, I am seeking a working example of how to control the viewing of data by different user groups. For example, I have 4 organizations who each place data into a shared Access database. I do not want want organization 1 to be able to view organization 2/3/4 data. I would like to have a sleek, friendly interface form for my organizations to each enter 10 items (things like bio, status, description, or just items 1-10) but not be able to view each other's records. I need a working example so I can emulate best practices when I build my own.
A solution using VB.NET & SQL would be preferred, but MS Access is the next best thing.

How good are you at VBA...?
Do you already have a login system in place that identifies the Users Group?
In a nutshell, the use logs on, and the "Group" is stored in a global variable
Then create a function to retrieve this value.
Then all forms and Reports have a recordsource that filters for only that group.
SELECT *
FROM YourTable
WHERE GroupID=GetGroupID()

Why not post what you have so far?
Instead of forcing us to create a working example from scratch?
...and "guessing" about all of the aspects of your current database...?

Besides, there really cannot be a hard defined "Best Practice", until you tell us your very specific needs:
Security?
Preferred filtering method?
Skill level?
Current Design?
...etc
I can think of at least three different ways to approach this, ...all following a different set of "Best Practices"
Here is a very basic example

...and this is a mod to insert the Group into all new records
Set the default value property of the Group control to the function: GetGroup()
I am sure you can examine this db completely and see what was done here.

Jeff, Thanks for the quick response!! I'm looking at your example files right now. I'm familiar with VBA to the extent that I can write beginner level code. I'm comfortable with VB.NET.
I do not have anything for you to work from. I'm trying to meet the need of a future requirement. I was hoping I could see what the community already had in their bag before I try and reinvent the wheel. :-)

Jeff, I was able to completely understand this example and am in the process of building my own based on yours. Thanks!!!

BTW if you are wondering why I use the function instead of the variable (to filter the form), ...it is because you can use the function anywhere (like in a query)
(You can use a function for query criteria directly, but not a code variable)
SELECT *
FROM YourTable
WHERE Group=GetGroup()
Also at some point the function can be modified to include validation, and.or other arguments.
