- 3. Page 3 Description:United ParcelService of North America, Inc.,typically referred to as UPS, is an American global package delivery company It delivers more than 15 million packages a day to more than 6.1 million customers in more than 220 countries and territories around the world. UPS have a complex costing process. It involves categorizing the data into domestic and international and do separate costing on the basis of different territory, services,shipper etc. Objective of this migration project is to migrate the logic of domestic costing from mainframe to datastage environment, which will create different files that would act as a feed for Calculator to do the costing. This involves understanding the existing mainframe logic, converting it into datastage object, comparing the result of both system and matching it till accepting limit, debugging and release support. Responsibilities as ETL Consultant: Inolved in all the phases of SDLC ie planning, designing, coding, testing, implementation and support. Understanding the mainframe logic of costing process and streamline the datastage code to that process. Use of different extraction stages of datastage ie, Sequential file stage, dataset stage, Oracle enterprise stage, DB2 connector stage. Use of different transformation stages of datastage like transformer, funnel, filter, sort, remove duplicate, aggregator, change capture, copy, checksum, join, lookup, merge, pivot stage. Use of different loading stages like sequential file stage, dataset stage, peek stage. Use of datastage director to schedule, monitor, trigger, stop, reset, validate diffetnt jobs/sequence. Usage of different partitioning technique to improve the performance of jobs. Consultation and coordination in implementing datastage jobs. Use of shell commands to navigate through directories, validating data in files, running the job through shell command. Acting as an Datastage SME for all queries related to datastage, bringing Mainframe resources ,who are moved to datastage, up to speed. Working on alternate effiicient design approach for conversion while keeping the core design of mainframe intact. Doing parallel run and comparing the legacy and new results and ensure it’s same from both side. Acting as an SME of datastage and mentoring a team of 8. End to end implementation of Datastage code. #2 Name: Mainframe Migration (MFM), Account Merge Client: DOWJONES (September 2011- August 2013) Team Size: 14 (Onsite-Offshore model) Environment:Datastage V8,Datastage V9,Cognos 8.3, DB2, UNIX, PL/SQL Description: Dowjones is a leader in news and business information world-wide, Dow Jones is newswires,Web sites, newspapers,newsletters,databases,magazines, radio and television. Objective of this project is to migrate print customers from the legacy mainframe system to the new framework (MOSAIC) and to provide Dowjones users a single view to access all accounts. These projecs are to provide different reports and support adhoc queries for making intelligent business decisions based on data available in various tables/views collected over a period of time. The activities of the project ranged from data extraction, staging and loading into data warehouse through Datastage.
