What is the hierarchy of data integration?

When asked a question like this, it is a good practice to pause before responding. This not only confirms that the interviewer has finished asking the question and is ready for your answer, but it also gives you time to organize your thoughts. This is especially important when you are asked to put individual items into a specific order.

"The typical hierarchy of a typical data integration project is Project, JOB, WorkFlow, and DataFlow. WorkFlow contains scripts used to define the source and queries. DataFlow defines the target datasets and how the data will be exchanged, which are known as transformations. Components of these include data, files, tables, and objects."
