A geodatabase topology is an item that’s stored in a geodatabase, just like a feature class or table. They can only exist and function within a geodatabase. Other formats, such as shapefiles, do not support geodatabase topologies. Like feature classes and tables, you must create the topology. This will include giving it a name, setting tolerances, adding rules, and adding participating feature classes. To create a new geodatabase topology, a couple of things must be true.

First, you can only create a geodatabase topology within a feature dataset. Second, only feature classes stored in the feature dataset containing the topology can participate in that topology. Third, participating feature classes must not be part of another topology or geometric network. A feature class can only participate in one topology or geometric network at a time. Lastly, you must have a Standard or Advanced license of ArcGIS Pro to create a new topology.
