Cloud Data Migration, the body must move broad data into a cloud distribution center. These assignments incorporate source management and planning (mapping), making a data pipeline for each table, and pursue changes over all data sources between others. However, there are various approaches to dispose of failures by utilizing automation. For example: Selecting ETL over ELT: In Extract, Transform, Load, data is extracted from data sources like OLTP database A and B and then deposited into the dimension authority (Staging Area). After that, the data is clean and transformed into a logical data warehouse. In comparison, ETL needs data to pass through a secondary server.
