Topology errors ors areviolations ofthe rules that you can easily find and manageusingthe editingtools found in ArcMap. Topology rules allow you to definethespatial relationships that meet theneeds ofyour data model. Topology rules allow you to definethose relationships between features eatures in a singlefeatureclass or subtypeor between two featureclasses or subtypes. Topology in ESRI®ArcGIS®allows you to model spatial relationships between featureclasses in a featuredataset.
