Which database in Epic is known for containing real-time data?

Chronicles is the database in Epic known for containing real-time data. It serves as the foundational database for the Epic electronic health record system and is primarily used for transactional data, including patient encounters, orders, and clinical documentation. This immediate accessibility allows for prompt updates and retrieval of patient data, which is crucial for clinical workflows and decision-making processes within healthcare settings.

The other databases mentioned serve different purposes. Caboodle is a separate data repository optimized for analytics and is often used to support reporting and business intelligence needs but does not provide real-time data in the same manner as Chronicles. The Data Warehouse is similar in that it aggregates data from various sources for analysis and reporting but is not focused on real-time transactions. Hyperspace is an application layer that provides users with access to the Epic systems and data but does not itself function as a database storing real-time information.
