Which table contains the column for storing a patient's Epic ID?

The correct choice is the PatientDim table because this table is specifically designed to hold unique identifiers and demographic details about patients. The Epic ID serves as a crucial link to the patient’s record within the healthcare data systems, allowing for accurate identification and data management. Since PatientDim focuses on patient-centric information, it naturally includes the Epic ID as one of its key attributes.

In contrast, the other tables listed each serve different purposes within the overall data model. MedicationDim is oriented towards medication-related information, ProviderDim contains details about healthcare providers, and MedicationOrderFact is focused on specific medication orders made for patients. None of these tables would typically include a unique patient identifier like the Epic ID, as their design centers on their respective domains rather than direct patient identification.
