5.2 Underlying technology

The underlying technology used in the pipeline is an open-source library of functions Targets, implemented on an open-source platform R.

The technology is a declaration and execution of computational nodes (tar_target) connected into a unified network (tar_repository) by input and output data sets (tar_objects). The network stores information about changes in the state of the original nodes and the content of the calculation functions and evaluates the relevance of the calculations at each node. In this way, tracing and control over the relevance of data at each processing node are achieved.
