Before you create a catalog source, ensure that you have the information required to connect to the source system.
Perform the following tasks:
•Assign the required permissions.
•Configure permissions to the service account that you use to access the Google Cloud Platform project.
•Configure a connection to the Google Cloud Storage source system in Administrator.
•Optionally, if you want to identify pairs of similar columns and relationships between tables within a catalog source, import a relationship inference model.
