Architecture of the core elements in PynPoint. The front end of the package contains the pipeline interface (Pypeline) which runs the pipeline modules that can read, process, and write data. The back end (DataIO and Processing) handles the connection to the central database (DataStorage) and provides the abstract interfaces for the ports and pipeline modules. There are interfaces for reading, writing, and processing modules, which all inherit from PypelineModule. Access to and storage of data occurs with the confined functionalities of the input, output, and configuration ports, which all inherit from the Port interface.
