Complete customer identity modelling (documents, biometrics, contact information)
-
Transaction flows with movement decomposition for complex payment scenarios
-
Digital access patterns (devices, IP addresses, sessions)
-
Account relationships and counterparty management
-
Comprehensive constraint definitions ensuring data integrity
Supported Use Cases:

Extensions
Fraud Event Sequence Data Model
Extension of Transaction and Account Data Model This model extends the base Transaction and Account Data Model above with event-specific nodes and relationships. You must implement the base model first before using this extension. |

Key Features:
-
Adds event nodes (
Connection
,ChangePhone
,ChangeEmail
,ChangeAddress
,AddExternalAccount
,Transfer
) -
Chronological event sequencing with
:NEXT
relationships -
Tracks old and new values during account takeover scenarios
-
Links events to existing Session nodes from base model
-
Maintains full compatibility with base model queries
Supported Use Cases:
-
Real-time fraud pattern detection through event sequences
-
Account takeover investigation acceleration
-
Weak signal detection in rapid event sequences
-
Suspicious activity timeline reconstruction
-
Event-driven alert generation
Using These Models
Each data model includes:
-
Node and relationship definitions with complete property specifications
-
Constraint and index recommendations for performance and data quality
-
Executable demonstration code for testing and validation
-
Integration guidance for connecting to existing systems
-
Query patterns for common business scenarios
These models can be implemented directly or adapted to fit your specific data sources and business requirements.
