ETL Architect

• A short project focusing on Data Synchronization from Enterprise non-relational distributed Big Data ERP system called Momentum on Oracle 11g backend to local In-house reporting database for the identified tables on Oracle 11G for financial reporting using Business Objects Data services as ETL tool. The following are the main activities accomplished:
• Identifying the Change Data Capture mechanisms and statistically validating for the truthful synchronization of changed data using time based changed data identification.
• Momentum system is ORM service oriented architecture without any relationships present at the database level, thus, modeled the reporting database with inherent relationships for the identified reporting schema.
• Identified the Data Integrity validation mechanisms and synchronization validation mechanisms.
• Created ETL jobs using SAP Data services for data replication.
• Identified and presented means for truthful replication as the data provision is done through segmentation for constituent components in the Enterprise system and as the segmentation layer issues could prevent the reporting scheme to be unstable relationally.
• Worked as a DBA in creating the consolidated script for reporting schema creation, table relationships establishment and indexing for performance improvements.
