Data Management Salesforce Interview Questions

1. Is it necessary to define an explicit primary key in custom objects?

2. In which order, we upload data in salesforce for related objects?

When loading data into a salesforce application dependencies between objects determine the order in which objects are loaded. If there is a one-to-many relationship between A and B, the data for A should be loaded before the data for B.

3. What is Upsert and how external id are beneficial?

Upsert is an API function that combines insert and updates into a single call. Upsert uses an indexed custom field or external ID to determine whether to create a new object or update an existing object.

  • If the external ID is not matched, then a new object is created
  • If the external ID is matched once, then the existing object is updated
  • If the external ID is matched multiple times, then an error is reportedUse Upsert when importing data to prevent the creation duplicates.
