Model data management

Model data management#

Polaris model inputs consist of a multiple files of different types (SQLite databases, JSON files, Python scripts, CSVs, etc.), while outputs also consist of HDF5 files in both its native form and OMX, the industry-standard format for storing matrices (skims, in our case). The model structure is further detailed in Anatomy of a Polaris model.

As it is desirable to version-control model inputs to track changes and document the model evolution, Polaris-Studio has long provided a solution for storing model data in git repositories, detailed in Storing models with Polaris-Studio.

In most transportation and energy studies is also desirable to manage multiple scenarios for the same model, which Polaris-Studio supports through a scenario management system detailed in Configuring stored scenarios.
