What type of relationship should be used to link demographic information to a model in Contact Builder?

In Contact Builder, linking demographic information to a model typically requires a one-to-one relationship. This type of relationship means that each demographic record is unique to a single contact. Essentially, for every contact in your model, there is only one corresponding set of demographic information.

This setup allows for clear and unambiguous associations between contacts and their demographic data, ensuring that each piece of information is directly tied to a single individual without confusion or overlap. When demographic data, such as age, gender, or location, is structured in this way, it supports effective targeted marketing and personalized communication without the risk of misalignment between contacts and their respective demographic details.

Utilizing a one-to-one relationship streamlines data management and enhances the accuracy of reporting and insights derived from the demographic information associated with each contact.
