and etc. Legacy system involves various stages like Launching pad where flat semi / Unstructured data is

stored in a file system and later processed for File Validation and staging processes in Teradata Platform

(Staging processes like - Clean Staging, Subject Area Staging, Load Ready Staging). Post staging, the

processed data is stored in ICDW integrated Data-warehouse for access by downstream applications. The

current heavy staging processes and file storage is migrated to Hadoop systems utilizing its massive

parallelism and storage power.
