"Real-time data migration is one of the more critical functions of a data migration team. Businesses depend on usable data to make decisions and operate the company. Having real-time data provides decision-makers with the most up to date information. This is particularly important in businesses that operate in dynamic industries in which conditions are continually changing. It is also essential for companies that execute real-time transactions, including retailers and financial firms."

This question is meant to explore your understanding of the link between data migration and the business objectives of the organization. The data migration in itself is only as useful as the information it provides to the organization to run the business. Understanding the link between these two processes is critical. The interviewer is seeking to confirm that you are aware of this.

"The purpose of a data warehouse is to provide useful information to the business and its decision-makers. Real-time data migration into the warehouse enables the decision-makers to have the latest data with which to manage the business. This is especially important for companies that use OLTP, such as retailers or financial firms."
