Modules (I worked on): KUMV Spladder
Scope of KUMV Spladder:
KUMV-Spladder is a connector between payment format of SAP/BCB and payment format of
Deutsche Bank to transform.
K2B process is the ETL transformation of the transactions from ZVKK to BCBPS.
It takes KUMV file on the mainframe of the ZVKK system is the input file and creates mandant
(legal entity) specific XML,TXT and ZIP files as the outputs in a dropbox mounted on unix. Also
a mainframe dataset is created with the transactions which have errors.
B2K process is the ETL transformation of the transactions from BCBPS/SAPDM to ZVKK.
The XML & TXT files from BCBPS/SAPDM act as inputs for B2K process and KUMV output file
and error file are created on the ZVKK system.
EoD process is the end of day process which involves collection of eDATA records from all the
B2K processes run during the day and create the mainframe dataset for eDATA

Key Roles:

  • Involved in all phases of SDLC from requirement gathering, design,
    development, testing, production, user training and support for production
  • Create new mapping designs using various tools in Informatica Designer like
    Source Analyzer, Warehouse Designer, Mapplet Designer and Mapping
  • Used Informatica reusability at various levels of development.
  • Developed mappings/sessions using Informatica Power Center 9.1 for data
  • Performed data manipulations using various Informatica Transformations like
    Filter, Expression, Lookup (Connected and Un-Connected), Aggregate, Update
    Strategy, Normalizer, Joiner, Router, Sorter and Union.
  • Developed Workflows using task developer, Worklet designer and workflow
    designer in Workflow manager and monitored the results using workflow

Project Description:
The objective of the project is to process the data from source
files by performing ETL to develop job streams for the interfaces, which will process data from
source files to target files and generate automated reporting capability for its client businesses.
These are met by the Extraction, Transformation, Loading and Reporting using Data stage.

Key Roles:

  • Involving in meetings with business team and analysts to gather the
    requirements. Understanding the functionality of the system & understanding
    business rules.
  • Used most of the stages like lookup, transformer, copy, joiner, filter, aggregate,
    sequence and modify etc.
  • Responsible for creating data stage jobs considering the performance issues.
  • All file paths must be parameterized to allow runtime flexibility and ease of
    migration between various server environments.
  • Time to time analysis of performance of jobs and making performance tunings as
    and when required.

Consip’s RGS Data Warehouse


Project Description:
The target project is Consip’s RGS Data Warehouse (or DW-RGS): the decision support
system developed and maintained since year 2001 by the Italian government to support the
national accounting and balance policies.
The DW-RGS consists of three database functional areas, each identified by at
least one separate database schema: the Staging Area (“STG”), the Enterprise Data Warehouse
(“EDW”) and the Data Marts (“DMA”). The STG structures are loaded partly by directly
importing data from the originating systems by means of database utilities and partly using
source systems flat files processed by ETL jobs, while the EDW loading from STG data and DMA
loading from EDW data are done using ETL jobs.

Key Roles:

  • Extraction, Transformation and Loading of data from oracle sources, flat files into oracle database
  • Developed Parallel jobs using stages Transformer, Aggregator, Sort, Modify, LookUp, Join, Oracle Enterprise, Peek, Funnel, Remove Duplicates etc
  • Consolidation of job designs and Fixing jobs according to informatica jobs
  • Involved in preparing issue documents.
  • Using Aqua Data Studio to check the data in the Database like Oracle
  • Involving in Unit testing
  • Involve in taking the backup of whole project for Daily-basis and weekly basis

Cycle Data warehouse

Coned Edison, USA.

Project Description:
Consolidated Edison Company of New York (Con Edison), a regulated utility, provides
electric service in New York City (except for a small area of Queens), and most of Westchester
County. The company encourages customers to learn about other electric and natural gas
companies — known as energy services companies (ESCOs) — and to compare the pricing
options and services that they offer. When a customer chooses to buy the energy their home or
business uses through an ESCO, however, Con Edison still continues to deliver the electricity and
gas, and responds if there is a service emergency

Key Roles:

  • Analysis and design of ETL processes.
  • Have used Transformer, Lookup, Joiner, Remove Duplicates, Merge, Pivot Stages
    and Funnel for data processing. Identify other source systems like Oracle, related
    tables and fields and ensure data suitably for mapping.
  • Involved in exporting and importing data stage jobs
  • Using Sequential file Sage, to extract data as a source, to target using oraOCI9i
    Stage, Using Transformation Stage, Aggregator Stage, Modify Stage for Data
    preparation to server jobs in DataStage Designer.
