What is a Replication ID in Microsoft Access and When Would I Use One?

In this Microsoft Access tutorial I'm going to teach you what a Replication ID is and when you would ever possibly use one. Replication IDs come up a lot for my students in Access Beginner 3, and today, we'll cover what they are and when you might use them. Generally, it's not something most people use, but it's handy for setting up a replicated database, especially useful in areas with little or no Internet service. In this video, I show how to set up a replication ID for a contact table to ensure no conflicts arise when merging data from two different databases. Although Microsoft removed the replicas feature, you can still use this method with a little bit of code. I also asked ChatGPT about the probability of generating two identical GUIDs, and it turns out to be negligible.
