Which of the following best describes 'pull technology' in HIE?

In the context of Health Information Exchange (HIE), 'pull technology' refers specifically to the method by which data is accessed from a centralized repository or database. This approach allows users—whether they be healthcare providers, organizations, or patients—to retrieve or "pull" relevant information as needed. The reliance on a centralized database means that users do not necessarily receive data automatically or in real-time, but instead request it when they require access to specific information.

This contrasts with other methods, such as push technology, which involves the automatic sending of data to users without their immediate request. In the case of HIE, 'pull technology' thus emphasizes the interactive nature of data access, allowing users to access and retrieve necessary information on demand, rather than relying solely on automated distribution systems.
