Quizplus · Accepted Answer

In a bottom-up data warehouse architecture, initial data marts are built one at a time and then gradually integrated into a larger data warehouse as needed. This approach allows for flexibility and scalability, allowing new data marts to be added and integrated over time. Therefore, the correct choice is B - the data marts may ultimately evolve into one data warehouse. Choices A and C are incorrect because they imply a lack of flexibility and evolution in the data warehouse architecture.
