What other ETL tools have you worked with, such as Oracle Materialized Views or Data Vault?
💡 Model Answer
I have experience with several ETL tools. With Informatica PowerCenter I built data pipelines that extracted from Oracle, transformed using mapping logic, and loaded into a Snowflake warehouse. In Talend Open Studio I used components for data quality checks and scheduled jobs via the Talend Scheduler. I also used Microsoft SSIS for on‑prem data integration, leveraging its built‑in connectors and control flow tasks. For big data, I worked with Apache NiFi to ingest streaming data from Kafka, apply transformations, and push to HDFS. Additionally, I have used Oracle Materialized Views to pre‑aggregate data for reporting, and I have designed a Data Vault model in a Snowflake environment to capture historical changes. These tools helped me build scalable, maintainable data pipelines.
