A hospital administrator wants real-time ED wait ×. Which database?

Data warehouses are optimized for analytical processing and reporting, not for real-time data capture. They aggregate data from multiple sources for long-term analysis, making them unsuitable for immediate operational needs like tracking ED wait times.

While relational databases can support a variety of applications, including transactional processing, their design does not inherently ensure real-time performance. They require careful indexing and optimization to manage real-time data effectively, which may not be as efficient as a dedicated transactional database.

Registries are typically used for storing and managing data about entities, such as patients or healthcare providers, rather than for real-time operational data. They are not structured to handle the dynamic and frequent updates required for monitoring ED wait times in real-time.
