layer data is loaded to MLZ.MDM process is used to standardize the data in MLZ layer and the golden records
are loaded back to these layers again.
EDM is an enterprise data management project which is focused on building the centralized data ware house
for various reporting purposes. This involves creating and loading dimensions and facts from source tables on
oracle and sql server. Each party and the related contracts signed,along with their membership information is
processed from MDM tables and loaded to dimension tables. An aggregated fact table is also loaded for the
party with accumulating snapshot information.

Project: Direct sourcing Provider- Phase 3(CSA-EDW)
Description:
The Client is one of the world's largest healthcare insurance provider companies.
The objective of the EDLR3-Direct sourcing Provider- Phase 3(CSA-EDW) project is to load the provider
specific information from CSA tables to EDW tables using bteq scripts.The aim is to load the changed or new
source data from various CSA tables to EDW tables. During this load the derivation of coupled code for each
source row is done by look up on translation tables.

• Technical guidance to the team members
• Identify the changed or new records using Teradata bteq scripts
• Applying business logic to source data using teradata
• Derive source coupled code logic through look up on translation tables

Project: Direct Sourcing COA-FACETS Phase-3
Description:
The objective of the ‘IM EDL-EDW Direct Sourcing to EDL R2.3’ project is to develop a detailed approach to
source the data from different sources (Core FACETS, ACES and NASCO) directly to the EDW (Enterprise
Data Warehouse) base model.Our concern was to load the Core FACETS COA data into the target EDW
environment. COA History data will be loaded from the Core FACETS Product tables, Core FACETS
Extension tables and Finance IT tables of the Core FACETS database. The on-going plan is to load only the
new or changed records to the EDW base model to capture the changed data in the Core FACETS Product,
Extension and Finance tables.
COA History data and the Incremental data will be first loaded into the Conformed Staging Area (CSA) and
most of the business transformations will be applied to the data before it is loaded into CSA.
Role:
• Come up with multiple design approaches and recommend the best possible solution
considering all the constraints
• Extract transform and load the COA FACETS data from source flat files to EDW database
• Writing complex Teradata SQL query to derive COA related chartfields for the source records
• Performance tuning of the existing ETL process,Teradata SQL
• Code Reviews
• Analyzing and providing solutions for the issues raised by development team
• Preparation of test plan, strategies, test cases, building and testing of the Informatica mappings

Project: Direct sourcing Provider Phase-1
Description:
The purpose of the EDW - Direct Sourcing of WGS 2.0 project is to source WGS 2.0 data directly to the EDW
base model.
In provider two source system
> WGS
> CS90
In WGS Provider data will be sourced from three different systems-
> EPDS
> NMS
> WMS
The EPDS system will be a single source for information for Institutional Providers. The Professional Data will
be loaded from the WMS and NMS Systems directly until this data is migrated into the EPDS system.
Data will be extracted from the WMS/NMS operational source systems and moved to a landing zone Teradata
tables. The data would then be mapped from the landing zone to the CSA tables. All the transformation logic
will be handled from landing zone to CSA feed. There will be two loads one for history data and another for
incremental.
The WMS/NMS and EPDS data will be loaded to the EDW on daily basis.
Role:
• Preparing high level and low level design document for ETL applications, Source –Target
mapping documents
• Working with heterogeneous sources – mainframes, RDBMS
• Develop mappings and workflows to load source data from Cobol files to Landing zone area
• Load data from LZ to staging and staging to EDW using Teradata bteq scripts
• Technical Guidance to team members
