What join condition is used when joining EncounterFact to PatientDim?

When joining EncounterFact to PatientDim, using INNER JOIN on EncounterFact.PatientDurableKey and PatientDim.DurableKey is the appropriate condition. This join condition is often utilized in data models to connect two tables that represent different entities while still sharing a common attribute, in this case, the durable key.

The durable key is an important identifier that represents a unique and consistent reference for a patient across different encounters, making it essential for accurately associating patient-specific data in a wide array of healthcare analytics. By using these keys to establish the join, the relationship becomes clear: each encounter can be linked to the corresponding patient in a reliable way, allowing for effective data retrieval and analysis.

In contrast, other options, such as joining based on patient IDs or current status indicators, may not provide the same level of uniqueness or may lead to mismatches in the data. The durable key is specifically designed to maintain continuity and integrity in data relationships over time, which is crucial in healthcare data models like Caboodle.
