To initiate the mapping process in toFHIR, the tool must be deployed in a data source center where it can access the relevant healthcare data. For instance, if the data is stored in a file system, toFHIR should be granted access to the file. Similarly, if the data resides in a database, toFHIR must have the necessary credentials and permissions to connect to and retrieve data from that database.

A repository is set up to store the mappings and jobs defined for the toFHIR server. This repository serves as a central location to manage these definitions. Additionally, the toFHIR graphical user interface module is deployed alongside the engine and establishes a connection with the backend server. This integration provides a user-friendly interface to efficiently manage the toFHIR tool, simplifying the process of mapping and job management.
