Real-World Scenario: Duplicate Customers Are Being Created During Integration. How Would You Prevent This?

Question

Accepted Answer

I would use multiple layers of protection:


Create Alternate Keys using Customer Number or Email
Implement Duplicate Detection Rules
Use Upsert Operations instead of Create
Validate data before insertion
Implement integration error handling


Architect Perspective:

Alternate Keys combined with Upsert operations are generally the preferred enterprise solution because they ensure idempotent integrations.

Follow-up Question:

Q: Why is Upsert preferred?

A: Because it updates existing records when found and creates new records only when necessary, preventing duplicate data.
