Data 360 has two types of attributes in segmentation: - Direct attributes (1:1): Attributes that have a direct relationship in a data model object, meaning a user has only one value, for example, postal code or first name. - Related attributes (1:N): Attributes that have a one-to-many (1:N) relationship, meaning they could have many values per attribute for a specific user, for example, purchases or email events. - Individual: An Individual profile represents an instance of a person from an external system, such as a SubscriberKey from Engagement. To get each instance of a person into the data extension, you segment and activate audiences at the Individual level. - Segment: A grouping of data that shares some set of characteristics, for example, customers who have the same birthday. - Unified Individual: A Unified Individual is a grouping of separate Individual profiles that relate to a single Unified Individual profile. These relationships are based on your [Identity Resolution and Reconciliation Rules](https://help.salesforce.com/s/articleView?id=data.c360_a_reconciliation_rules.htm&release=264.0.0&type=5 "A reconciliation rule specifies how to select a single value to save to a unified field that can’t have multiple values, such as an individual’s name, during the identity resolution process. Reconciliation rules are set at the object level and can be overridden by field-specific reconciliation rules. The reconciliation process doesn’t delete or change any source profile data, update your connected source systems, or tell you which source data to use when working with your customers."). To include attributes from multiple Individuals into a single data extension row, segment and activate audiences at the Unified Individual level. ## Marketing Cloud Engagement Terms - Attribute: Information or data about a contact found in a data extension created as part of a Data 360 activation. You can use attributes throughout Engagement for content personalization, Omni-Channel messaging, or journey decisioning. For example, a contact’s gender. - Attribute Group: A logical grouping of data extensions that make up the Contact Model within Engagement. Data specialists can manage attribute groups and their associated data extensions within the Contact Builder app. - Channel Address: The address where a message is delivered. For the Email channel, it’s EmailAddress. For the SMS channel, it's PhoneNumber. For the MobilePush channel, it's SubcriberKey, which automatically sends to all the corresponding devices. - Contact: A contact represents an instance of a person that you can send messages to. A contact can be associated with one or many channels. The concept of contact is similar to an Individual in Data 360 and a SubscriberKey within Engagement. - Contact Model: A collection of attribute groups that define a person within Engagement. You can use data related to the Contact Model more widely throughout Engagement, including Journey Builder. - Data Extension: A table that stores data in Engagement. You can use a data extension for data storage or for sending messages to customers. Each Data 360 activation creates and populates a data extension in Engagement. - Data Foundation: An implementation where you activate data from Data 360 into the Engagement Contact Model. Easily refresh and reuse this data across Journey Builder for journey decisioning, wait until and exit activities, as well as the content personalization of event-triggered journeys. - Journey: A marketing workflow that orchestrates a series of personalized messages, decision splits, and other activities. Marketers create journeys in Journey Builder. - Omni-Channel Contact: In the context of this solution kit, a person represented by one SubscriberKey in Engagement. This SubscriberKey has an associated address for each channel: Email, SMS, and MobilePush. Omni-Channel contacts can execute each channel within an Omni-Channel journey. - Single-Channel Contact: In the context of this solution kit, a person represented by three different SubscriberKeys in Engagement. Each SubscriberKey has only one associated channel address: Email, SMS, or MobilePush. - SubscriberKey: A SubscriberKey is an identifier that represents an instance of a person or contact that you can send messages to. A SubscriberKey can be associated with one or many channels. The concept of SubscriberKey is similar to the concept of Individual in Data 360 and Contact in Engagement.
