Information about a medical provider's locations, brands, and gateways can be received (e.g., via an online portal). This information can be used to generate a data object that represents relationships between the locations, the brands, and the gateways. This data object can be maintained in a database base that is searchable by a user device. For example, a user of the user device may search the database to identify a medical provider where the user obtains care. Once identified, other systems can be used to connect the user device to a gateway associated with the medical provider in order to download electronic health record data associated with the user.
