Purpose

The main goal of the Fraud Detection mechanism is to provide a possibility to identify and prevent possible financial losses due to fraud activities. In order to be able to do that there is a necessity to create fraud DB and using it implement triggers which automatically shows who is likely to be fraud.  

Fraud DB structure 

To simplify report creation and data analysis current tables should be denormalized  and aggregated.

Table for replication

1. prm_db
   
   • legal_entities
   • divisions
   • employees
   • parties
   • party_users
   • black_list_users
   • audit_log
2. ops_db
   • declarations
   • declarations_status_hstr
3. il_db
   
   • declaration_requests
   • employee_requests
   • dictionaries
4. mpi_db
