We need a new tool that can help us tackle this. Here is where object tables come into the picture.

Tables are extremely useful, and yes, we can create them in the geodatabase too! However, how can we use tables to solve the multiple reviews problem? For each restaurant, diner, and so on, there might be multiple...
