What Is HealthVault?

HealthVault is a personal data platform that allows a user to record, collect, and share all health information in a central location. A key benefit of using HealthVault is its application programming interface (API), which applications and devices can use to provide value for the end user. As depicted in Figure 1-1, HealthVault enables an ecosystem of devices and applications, with use cases ranging from tracking diet and nutrition to connecting to hospital or pharmacy systems. HealthVault currently supports more than 300 applications and 80 devices. Some devices connect to HealthVault via the HealthVault Connection Center, a complimentary client application that enables devices to upload information directly to HealthVault from a Windows PC.
