I'm new to Salesforce but I've been given the assignment to import our data to Salesforce. In our old database, we have a lot of different information about companies and their people. In Salesforce, I see these data types:
Leads
Accounts
Organizations
Opportunities
Contacts
I assume that many of these are one-to-many relationships, but I'm not clear what the relationships are, nor does the documentation here explain:
https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_objects_list.htm
Is there any place that documents the exact relationship between all the default Salesforce objects?
