Proprietary Data on Intranet

Proprietary Data on Intranet

Proprietary Data on Intranet

Hello Folks,

I hope this isn't too long winded. I'm developing an application for a corporate intranet that handles proprietary chemical data for different clients.  I need help with some design aspects.

I need to design a form that allows different client managers to enter client specific data into a community data table, view/edit the data that they've entered, but not be able to view any other client's data in the same table.  I envision using just one table since there are lots of clients (100+) and individual tables for each one seems cumbersome.

I have a password protected login procedure to identify the person on-line and my idea for the data entry screen is to use a grid control attached to the community table for data entry.  My problem is how do I restrict the view of the data to just the data appropriate to the client manager in a multi user environment.  Or is there a better concept I should be using.  Any information would be greatly appreciated as this is my first multi user and on-line application.

RE: Proprietary Data on Intranet

There are several ways, assuming you'll have a CLIENTMGRID column in the table:

    1) set filter (easy but poor performer)
    2) create an updatable view with a bind parameter for the CLIENTMGRID column.

The way #2 works is you'll create a view in the View Designer; in the WHERE clause, you'll have something that evaluates to:  CLIENTMGRID = ?gcCLIENTMGRID
then in the login screen, set gcCLIENTMGRID to the logged-in user's ID.

I'm sure others can come up with some other approaches that may be even better suited to you.
