Identify the Caboodle column for the Administration Date key.

The Administration Date key is specific to the context of immunization events within the Caboodle data model. The column ImmunizationEventFact.AdministrationDateKey directly aligns with this context, as it is designed to capture the date when an immunization was administered. This key is essential for tracking immunization events and linking them to related patient records within the data model.

The other options do not correspond to the Administration Date key. For example, the HospitalAdmissionAttributedProviderDataMart.NumberOfDistinctDaysAsInpatientAttending pertains to inpatient stay metrics, which is unrelated to immunization dates. EncounterFact.EncounterEpicCsn is an identifier related to patient encounters, while PatientDim.Name is a dimension for patient names. None of these capture the specific date of immunization administration, making ImmunizationEventFact.AdministrationDateKey the correct choice for this question.
