Topology is the arrangement of how point, line, and polygon features share geometry. Topology is used for the following: Constrain how features share geometry. For example, adjacent polygons such as parcels have shared edges, street centerlines and census blocks share geometry, and adjacent soil polygons share edges.

What is topology in GIS?
Today, topology in GIS is generally defined as the spatial relationships between adjacent or neighboring features. Mathematical topology assumes that geographic features occur on a two-dimensional plane.
What are the different types of topology in ArcGIS?
There are two types of topology in ArcGIS Pro: map topology and geodatabase topology. You can use either or both to help you manage and maintain the accuracy of feature data with respect to coincidence, adjacency, containment, and connectivity.
What is the topology of a geodatabase?
Geodatabase topology comprises a collection of spatial rules that you can use to define relationships between features in a dataset. The workflow consists of defining a rule, validating the features, fixing errors, and marking exceptions.
How do I use topology in ArcGIS?

A topology helps monitor and protect the spatial relationships in a feature dataset. • A feature class can have no rules, a single rule, or several rules.
Topology expresses the spatial relationships between connecting or adjacent vector features (points, polylines and polygons) in a GIS.
