Creating a Maker and Checker in VB

My question is regarding a windows form application created using VB in Visual Studio 2008 with Microsoft SQL 2005 as my database.

I want to try creating an application that would require two users to function, i.e. the maker and the checker.

The Maker is the user that is in charge of making new data or changes to the data while the Checker simply approves the changes. This means that any changes made by the Maker will not push through unless confirmed by the Checker that everything is valid.

For example a table for users.

Username: KJ
If the Maker wishes to change KJ to KJI he first needs to update after which the Checker will approve the update and the queries will push through. Now I think it is simple if the Maker only edits or adds once at a time. But what if more than one changes or additions are necessary?


but still, for now, my main focus is creating a very simply program that can integrate this Maker-Checker function

Is it possible to make this happen? And is it possible to make this work through a networked system? Like one computer will be used by the Maker and the other the Checker?

Thank you
