The ETL loads all the fact tables with all these information and which can be used for reporting.
Responsibilities:
• Prepared the Technical Design Document for development and the Source-Target mapping
document
• Verified and validated data model structure and E-R modeling with all related entities and
relationship with each entity based on the rules using Erwin as per the business requirements.
• Develop ETL mappings which were designed to load data from Oracle sources into the Oracle
Staging/Target Area
• Used SQL Queries to extract data from the Oracle and MS SQL Server databases
• Performed backend testing using SQL queries and analyzed the server performance on UNIX
• Developed transformations such as Expression transformation, Filter transformation,
Lookup transformation, Joiner transformation, Aggregator transformation, and Update
strategy transformation.
• Executed Informatica work flows, verified the error logs
• Extensively used Informatica Debugger to validate maps and to gain troubleshooting
information about data and error conditions.
• Interacted with client user personnel to ensure continuing adherence to requirements and user

Projects Handled:
Informatica Upgrade:
Migration of all the informatica mappings and workflows from informatica version 7 to version 8. And
make the code runnable in informatica 8 environment along with reducing the performance issues.
Fist Call Resolution:
The First Call Resolution report tracks the non-repeat rate of authenticated callers using the caller’s
account number within a defined period (1day, 7 day, 30 day or 45 day). This report can be used to
measure the resolution of a caller’s requests with one customer placed phone call.
Previously the reporting needs were being met from the SQL server tables loaded through DTS. The new
proposed design will have ETL built to load the data into the target and will be sourced from existing
FACTS.There was a modification to existing fact to include additional columns. New facts were built to
support reporting needs of FCR.
Responsibilities:
• Develop ETL mappings which were designed to load data from Oracle and SQL Server sources
into the Oracle Staging/Target Area

Projects Handled:
Health & Welfare (HW) Process:
This project comes under H&W module of the total HR Outsourcing Project. This process can be
monthly, biweekly, weekly, or daily process, depending on the requirement. Flat files are the outputs in
this project. The process starts with the collating of data related to the employees and their dependents.
This data resides in some flat files called the client extracts. This collation of data also encompasses some
validation and cleaning up routines. This is the client process and is carried out by the client workflow.
The collated data at the end of this process is dumped into a table called the client table.
From the client table, we pick up the records which are applicable for this particular vendor, and produce
flat files containing this data.
Annuity Pension Process:
Annuity is one of the processes of Pension Payroll which pays the amount in specific frequency for
specified period of time. We take all the payment information, tax information, deduction information and
bank information of all the SSNs applying the selection criteria, specific to that client. By sorting we get
the most recent record based on the keys given in the top most position. Base table is created by joining
cbElectionBase and PMAS tables.
Normally the PMAS tables that we join are EMPLT, ADDRT and TERMT.Then a Full File is created
which contains different transactions containing deduction records, payment records and tax records
based on many rules specifying Business logic. Tempff is an intermediate table where we compare
Current FF and Previous FF.
In case of retro payments the amount also will be calculated there based on the specified time.Once the
flagging is completed,the new or changed records are moved to the ‘Changes Only File’. After which
Reports are generated based on client Requirement.
Responsibilities:
• Extensively worked on developing the ETL mappings which were designed to load data from
Oracle and SQL Server sources into the Oracle Staging/Target Area
• Writing technical design Document and Test Data.
• Used SQL Queries to import data from source of mapping like the Oracle and MS SQL Server
databases
• Performed backend testing using SQL queries and analyzed the server performance on UNIX
• Extensively worked on Relational and Flat files as Sources and Target.
• Tested mappings and SQL queries in transformations such as Expression transformation,
Filter transformation, Lookup transformation, Joiner transformation, Aggregator
transformation, and Update strategy transformation.
