## Demo Environment

**IMS Org**: Adobe Demo System Shared

**Sandbox name**: public-halliby

**Website**: [https://dsn.adobe.com/web/halliby](https://dsn.adobe.com/web/halliby)

## Demo Flow

With Adobe Experience Platform Identity Service and Real-Time Customer Profile, it is easy to assume that your data is ingested perfectly and that all merged profiles represent a single individual person through a person identifier, such as a CRMID. However, there are possible scenarios where certain data could try to merge multiple disparate profiles into a single profile (“graph collapse”). To prevent these unwanted merges, you can use configurations provided through identity graph linking rules and allow for accurate personalization for your users.

### Demo part 1: Graph algorithm

- Go to [https://dsn.adobe.com/web/halliby](https://dsn.adobe.com/web/halliby).
- Browse few pages anonymously
- Go to the registration - to create a profile or sign-in page - to log in with existing profile [https://dsn.adobe.com/web/halliby/registration](https://dsn.adobe.com/web/halliby/registration)
- Browse again few pages while authenticated
- Show John's identity graph ("ECID XXX is tied to John")

- Then go to [https://dsn.adobe.com/web/halliby/sign-in](https://dsn.adobe.com/web/halliby/sign-in) or register to create a new profile, log in using another email (Jane). DO NOT click log out. If you do, ECID will be reset and therefore you cannot showcase feature

- Browse while authenticated
- Show Jane's identity graph ("ECID XXX is now to Jane"), also profile viewer will show updated values against this ECID

### Demo part 2: profile & identity

- Now the ECID has transferred from John to Jane...but what about the events? who is associated to what event?
- Show profile behavior:
- Go to AEP → Profiles and select "No Stich Merge Policy"

- Go to John's profile - the one you created first in demo part 1 -> you should only see John's authenticated browsing activity

- Go to Jane's profile -> you should only see Jane's authenticated browsing activity - the first event would probably be registration/sign in

- Go to ECID profile -> you should only see unauthenticated activity on ECID
