How is data transformation used in the cloud?
The scalability of the cloud platform lets organizations skip preload transformations and load raw data into the data warehouse, then transform it at query time — a model called ELT ( extract, load, transform). Processes such as data integration, data migration, data warehousing, and data wrangling all may involve data transformation.
