Step 1: an asymmetric key -
A master key should be created only once in a database.  The Database Master Key is a symmetric key used to protect the private keys of certificates and asymmetric keys in the database.
Step 2: a database scoped credential
Create a Database Scoped Credential. A Database Scoped Credential is a record that contains the authentication information required to connect an external resource. The master key needs to be created first before creating the database scoped credential.
Step 3: an external data source -
Create an External Data Source. External data sources are used to establish connectivity for data loading using Polybase.
