What operations are executed in a data migration system, and in what order?
"Regardless of which data migration tool you are using to transfer data from the sources into a data warehouse, the operations performed are similar. The three distinct processes are extracting the data from the source, cleansing or validating it, and then writing it to the target database or data warehouse."
This is another technical question. The nuance of this question is that not only is it asking you to define the steps, but also asks what order in which they are performed. This will ensure that you are knowledgeable about this process and have used it before.
"The typical data migration system consists of three distinct operations. These include extracting the data from the data source, which can be an Oracle, Microsoft, or any other relational database, transforming the data by performing a data cleansing and validation process, and writing the data into the target database or data warehouse."
