To track different form submission events, how should the XDM schema be structured?

The correct answer is to create one experience event schema and use the identity map. This approach allows for a consolidated and efficient way to track various form submission events within Adobe Experience Platform. By utilizing a single experience event schema, you can standardize the way data is collected and processed, which simplifies the integration and management of events.

The identity map plays a crucial role as it helps in connecting the various user interactions to specific identities, providing a comprehensive view of the interactions associated with each user without redundancy. This enables better analysis and reporting as all events can relate back to the same user profile, making it easier to understand user behavior and the impact of different forms.

In contrast, creating multiple experience event schemas would complicate the tracking process, as it would lead to fragmented data across different schemas, making comprehensive user journey analysis more challenging. Meanwhile, a single schema for all data types could lead to a loss of specificity and detail, as diverse form submission data might contain unique attributes that would benefit from dedicated tracking. Finally, using separate datasets for each form is less ideal, as it may hinder the efficient aggregation and analysis of data, obstructing a holistic view of user interactions across different forms.
