Correct Answer: B Transaction

The correct answer is:

D. Engagement

Explanation:

The Engagement data stream category is designed for time-based operations in segmentation and calculated insights. It focuses on event-driven, time-series data such as clicks, page views, purchases, or other interactions, making it ideal for operations that rely on time-specific attributes like timestamps or event dates.

Why not the other options?
• A. Individual: This is used for profile data (e.g., demographic or static attributes) and is not time-based.
• B. Transaction: This is a general category for financial or purchase-related records, but it is not specifically optimized for time-series operations.
• C. Sales Order: This is specific to order transactions and does not cover the broader range of time-based engagement data.

Use Case for Engagement:
• Identifying customers who interacted with a marketing campaign in the past 7 days.
• Calculating insights based on event frequency, such as “most active users this month.”

The correct answer should be D. Engagement

Select the Engagement category if your dataset is time-series oriented. When you set the data stream category to Engagement, you must define the event time using a Date or DateTime typed field from your source schema.
