https://doi.org/10.1007/978-0-387-77645-3Now that we have extracted the data from the source system, we’ll populate the normalized data store and dimensional data store with the data we have extracted. In this chapter, I will discuss five main subjects regarding data warehouse population in the sequence they occur in a data warehouse system:
