These flow zones clean and prepare the data at the HCP level  and do not aggregate marketing outreach across hospitals. In the first flow zone, the marketing  data are prepared in 'long' form - meaning each record represents a marketing interaction with a single HCP for any point in time.

In the second flow zone, marketing outreach to individual HCPs are joined with aggregate information about the provider's associated hospital or clinic.The output datasets include sales information at the aggregate hospital level, purely for information purposes. These data are only used to create specific charts on the dashboard and are not used in the modeling aspect of this project.
