Data 360 Consultant Data Ingestion And Modeling Practice Question
A consultant is mapping a custom Data Source Object (DSO) representing loyalty points to the Individual Data Model Object (DMO) in Salesforce Data Cloud. The DMO requires a primary key, but the loyalty source record only contains a compound loyalty program ID and member ID. What is the recommended best practice to satisfy the primary key requirement during the data mapping process?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a formula field in Data Streams to concatenate the loyalty program ID and member ID into a unique string, then map that formula field to the DMO primary key.
When mapping data to standard DMOs like Individual where a specific primary key format is expected, or when unique combinations are needed, consultants should use a formula field within the data stream or mapping canvas to concatenate the composite keys into a single unique string identifier.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Map only the member ID and accept potential record overwrites for members in multiple loyalty programs.
Why it's wrong here
Accepting record overwrites leads to data loss and is not a recommended best practice.
- ✗
Map both fields as the primary key simultaneously in the mapping canvas.
Why it's wrong here
Standard DMO primary keys accept only a single field mapping.
- ✗
Let Data Cloud automatically generate an internal GUID to act as the primary key.
Why it's wrong here
Data Cloud requires explicit mapping to primary keys and does not silently generate GUIDs for unmapped primary keys.
- ✓
Use a formula field in Data Streams to concatenate the loyalty program ID and member ID into a unique string, then map that formula field to the DMO primary key.
Why this is correct
Creating a formula field during ingestion or mapping allows the combination of fields to form a valid, unique primary key.
