Professional Experience

Project #1:

Role : Developer

Title : ILI Operational Data Store:

Period : Oct 2018 to till date

Client : Prudential Insurance Company of America

Work location: Roseland NJ, USA

Team Size : 5

Technologies: Oracle PLSQL, SQL, UNIX shell scripting, Autosys

Description:

The Operational Data Store (ODS) is the logically unified focal point for enterprise operational (as opposed to analytic) information, an integrated set of near-real-time transactional detail information optimized for operational runtime and extract efficiency, standardized to asset of consistent definitions and formats and assembled to provide an enterprise-level perspective. It is ACORD data domain-oriented.

The operational data store is the hub for enterprise operational information. Data is loaded regularly in to the ODS from the primary administration and accounting systems and is stored at the transactional detail level.

The data from ODS is fetched through Views/Mat Views and loaded to Pre-staging Area of the Warehouse through db links. From Pre-staging area, it is then moved to staging area through PL/SQL packages. From there it is loaded to Warehouse where data is stored in the form of Facts/Dimensions.

The IL Data Warehouse contains current snapshot data in the Operational Data Store (ODS) and historical data in the history data store (IMD).

Xerox Corporation is using Siebel application, which interfaces with

Multiple Systems to gather meter-reading data. The Project involves enabling auto-replenishment of

Supplies, GMS global metered supplies requires consumption to be estimated for devices that do not

Communicate gas-gauge level information.

GMS requires a reliable unit of measure that can be used effectively to estimate consumption. The raw meter count needs to be validated as reasonable, rationalized due to varying device characteristics, and updated frequently enough to support the estimation process. Following the completion of the current requirements being gathered the next step is to develop a high-level design, detailed design, develop, and test the new functionality for Meter Count Cleansing in GMS. The project involves configuration of Siebel inbuilt resources and functionality and customization of already inbuilt Siebel features and customizations using various Oracle provided tools, development of new User Interfaces using Siebel Tools and Siebel EAI/Web Services components
