How do i tie my custom table to Organization/Account in Sandbox?

Summary:

We can create our own custom tables in CDM using application composer → custom Objects along with custom fields

After creating a Custom Object, Can i do a import management for this custom Object ? if so can you please navigate me.

How can i link this custom object to my Organization/Account Root node which is present under standard Objects in Application Composer

How to find my custom object Data base Table?

Thanks,

Harshini
