The DBC file format has several advantages that make it a popular choice for storing and exchanging data: dbc file format documentation

The following is a technical overview and documentation-style breakdown of the DBC (Database CAN) file format. This format is the industry standard for describing the data within a Controller Area Network (CAN) bus, primarily used in the automotive industry.
