A compilation database (CDB) is a JSON file that specifies how each source file in a code base should be compiled. This JSON file is typically named compile_commands.json and resides in the root directory of a project. It provides a machine-readable record of all compiler invocations in the build process and is often used by various tools for more accurate analysis, refactoring, and more.
