system to capture the data. INC has not been able to produce reports from Customer database and the report
generation duration is too long.
As an alternative, the data will be transferred from INC to Data Warehouse on daily basis. The data will be
extracted from Data Warehouse in order to create analytical reports on need basis. Marketing groups can access
the reports as soon as the data is available.

6. JPMC’s Enterprise Systems Data Distribution (ESDD) has started a reengineering initiative of migrating
existing applications from mainframe technology to Ab initio technology. This currently provides support for the
functionality that has been built for Arrangement services (ARR) and Financial Account Processing (FAP). This
includes select transaction extract files, daily/weekly transaction loads to the FAP transaction databases. For ARR it
includes account extract files and bridges between Demand Deposit Accounting and ARR. It has also provided
conversion processes from legacy applications to target applications. Re-engineering will add value to existing
Business Functions with value derived from a simplified solution which can be enhanced at reduced cost and
shorter development time periods.
The scope of this project is to support development, testing (Unit, IST, and UAT) and implementation of
enterprise releases of ESDD systems. Development activities could be enhancing existing graphs/plans, developing
new graphs/plans or any other adhoc request from JPMC personnel.
TCS is also be involved in running / executing ESDD cycles as part of enterprise release testing.Delivery was
based on Agile methodologies.

collaboration from across the business and will impact 25,000.
Partners and has a high dependency on IT.The Pioneer project will implement an enterprise Supply Chain stock
management system that will enable us to have one view of our stock across the division.
Data Conversion:
The Consortium’s data conversion and migration approach is designed to ensure that the Oracle Retail modules
being implemented have the desired data for business operations. The success of the data migration and
conversion work stream is dependent on understanding the flow of business information requirements to inform
what data needs to be migrated.
The scope of data migration would broadly include the following.
• Identify all affected business functions, corresponding legacy applications and data source
• Understand and agree with relevant stakeholders on the data requirement of each application/module
• Coverage for all required master and transactional data
• Required manual conversion procedures and automatic programme
• Populate the target application(s) with migrated data that meets the project/phase timelines.
Data Integration:
As part of the Pioneer Programme, John Lewis is implementing several Oracle Retail Applications (ORA). Of these
Oracle Retail applications, RMS is being implemented to maintain supplier cost, across John Lewis branches and
online businesses. One of the requirements is to allow the RMS to send all the Supplier Cost Changes for a given
Item supplier to Product Hub. For Phase 1, only active supplier will be send to product HUB. As part of the interface
the ‘Recalc Order’ indicator is sent which informs Product Hub if any open Purchase Orders needs to be
recalculated. This document describes the process of updating the Supplier related legacy product hub tables from
the Oracle Retail side. Ab Initio ETL tool extracts the data from the RMS stage table, processes and ftp GDG file to
the mainframe. Then the data from GDG file will be extracted and loaded to Supplier related legacy product hub
tables.
