What does Identity Service do?
Identity Service links identifiers that belong to the same person into an identity graph. Real-Time Customer Profile uses that graph to decide which data fragments to merge into one profile.

What is an identity namespace?
A namespace labels the type of an identifier, such as ECID, Email, Phone or a custom CRM ID. Typed namespaces keep unrelated identifiers from being confused with each other.

What is the ECID?
The Experience Cloud ID (ECID) is the device or browser identifier created by Adobe's collection libraries. It is anonymous until a known identity such as a login is linked to it.

What is the primary identity?
The primary identity is the field a schema designates as the key for a record, for example a CRM ID for profile data or the ECID for web events. Choose one deliberately.

How does AEP merge a customer's updated email from CRM into the profile?
The record carries identities that link to the existing profile through the identity graph. The merge policy then decides which email value wins when sources conflict.

How can I merge multiple account IDs under one customer?
Ingest them with a shared linking identifier, for example a CRM or customer ID in a namespace common to all sources, so Identity Service connects the accounts into one graph.
Sources: Identity data type
How do I see all identities linked to a customer?
Open the profile in the Profiles area and review its linked identities, then open the identity graph viewer for the selected identity and namespace.
Some profiles are missing loyalty IDs. Where do I check?
Check the schema identity marking and namespace, whether the source dataset sends the loyalty ID, the identity map on sample profiles and whether the dataset is Profile-enabled.

What is a merge policy?
A merge policy defines how data from several datasets combines in a profile when values conflict, for example by timestamp or by giving one dataset precedence, and which identity graph is used.
Sources: Merge policies
What is the difference between timestamp ordered and dataset precedence merge policies?
Timestamp ordered lets the most recently updated value win. Dataset precedence ranks sources, so a trusted system of record can win even when an older timestamp.
Sources: Merge policies
Which source should win for regulated attributes such as occupation?
Prefer the system of record, usually KYC for regulated customer data, using dataset precedence in the merge policy, and document that decision.

What is the union schema?
The union schema is the combined view of all fields from schemas of the same class that are enabled for Profile. It is what audiences and profile lookups read from.
Sources: Union schema UI guide
What is a computed attribute?
A computed attribute is a derived value calculated from events, such as lifetime purchases, and stored on the profile for use in audiences. It refreshes on the service's own schedule.
Sources: Computed attributes overview
What are profile fragments?
A fragment is the piece of a customer's data that came from one dataset or record. Profile merges fragments into the single profile view.

How does graph-based stitching in CJA relate to AEP identity?
CJA's graph-based stitching uses identity graph information to connect anonymous and known activity across devices when reporting, separate from how profiles merge in Real-Time Customer Profile.

Which AEP service gives me a single customer view of merged attributes?
Real-Time Customer Profile, which merges attributes and events from several sources using identity and merge policies.
