Create a schema

Explorer allows you to create a schema by using GUI.

Note

  • Users can use the Schema drafting function to design schema visually. For more information, see Schema drafting.
  • Users can directly execute nGQL commands on the console to manage the schema.

Prerequisites

  • Your account has the privilege of GOD, ADMIN, or DBA. For more information, see Roles and privileges .
  • The schema is designed.

Note

If no graph space exists and your account has the GOD privilege, you can create a graph space on the Console page.
