In this video, we will discuss what is ETL (Extract, transform, load), what is data warehouse and the purpose of it. The difference between OLTP (Online Transaction Processing System) vs OLAP (Online Analytics Processing System). Apache nifi, talend, informatica are some the entreprise ETL tools whereas for data warehouse teradata, amazon redshift, snowflake, greenplum etc are widely adopted in the industry.
