-::: details Data Model Extensions…
-
-In order to showcase sensitive data and data subject details, we need to extend the data model a bit as follows:
-
-```cds [db/extensions.cds]
-using from '@capire/incidents';
-using { cuid, managed } from '@sap/cds/common';
-
-entity sap.capire.incidents.Addresses : cuid, managed {
-  customer      : Association to sap.capire.incidents.Customers;
-  city          : String;
-  postCode      : String;
-  streetAddress : String;
-}
-
-extend sap.capire.incidents.Customers with {
-  creditCardNo : String(16) @assert.format: '^[1-9]\d{15}$';
-  addresses    : Composition of many sap.capire.incidents.Addresses
-                   on addresses.customer = $self;
-};
-```

 So, let's annotate the data model to identify personal data.
 In essence, in all our entities we search for elements which carry personal data, such as person names, birth dates, etc., and tag them accordingly.
 All found entities are classified as either *Data Subjects*, *Subject Details* or *Related Data Objects*.
