I)Heroku Connect
II)Big Objects
III)Standard and custom objects
IV)Salesforce Connect

Q2)How do you display Big Object data within the Salesforce UI?
I)Use Asynchronous SOQL to query the Big Object data in real time, and surface it in a Lightning component.
II)Use Asynchronous SOQL to query the Big Object data in a scheduled Apex job, and surface it in a Lightning component.
III)Use Asynchronous SOQL to place the Big Object data into a custom object, then display the data in any part of the Salesforce UI.
IV)Use a scheduled Apex job to bring the Big Object data into a custom object, then display the data in any part of the Salesforce UI.
