CAREER HIGHLIGHTS

Client: Intact Insurance, Ontario, Canada Jun 2012 - Till

Now

Project: HCAI & GuideWire Jun 2012 - Till

Now

Role: Data Architecture, Implementing Data Vault,

Solution Design for Loading Data into Final Datamart

Health Claims for Auto Insurance (HCAI) is an IBC mandated electronic

system for transmitting Auto Insurance claim forms between insurers and

health care facilities in Ontario. HCAI data, which includes Insurer,

Facility and Payment information, will be stored in the OPUS system.

The native HCAI system provides none to very limited reporting

capabilities. As a result, the main objective of this project is to provide

the Intact AB claims business with an enhanced reporting ability. HCAI data

will be loaded into the OPUS system and linked to OPUS.

HCAI project has been initiated to modify already running ETL process and

add new load processes to migrate data from one of the INTACT front end

OPUS into Intact Enterprise Information System (EIS).

The EIS Guidewire Claim Center - Claims CL Property Project introduces a

new operational Claim System at Intact which will feed claim data to EIS.

The Guidewire Claim Center (GWCC) application will initially handle only

Commercial Line Property claims (select products), with subsequent phases

to handle other business lines. GuideWire is completely new project to

bring data from GuideWire Application into Intact EIS.

In this project, new DW Architecture call Data Vault (HUB, Link and

Satellite table) concept has been adopted.

My Role is

. Updating the Erwin Model EIS tables in INTACT EIS Staging, Dimension

and Layer 2 (final data-mart) Area as per requirement from HCAI using

Erwin 7.3
