 # Operate edge types
 
 After a graph space is created in Nebula Graph, you can create edge types. With Studio, you can choose to use the **Console** page or the **Schema** page to create, retrieve, update, or delete edge types. This article only introduces how to use the **Schema** page to operate edge types in a graph space.
