Is an Engine Calibration Management Database needed?

Is an Engine Calibration Management Database needed to control the proliferation of thousands of calibrations in an ECU? Or How is the release process managed internally with various groups? Traditional calibration methods use a combination of engine dyno and vehicle testing, but pressure to reduce powertrain development cost & time is driving development of advance calibration techniques. Moreover, future engines will feature variable valve actuation, that is necessary to improve fuel economy, performance, and emissions. This introduces a greater level of system complexity and greatly increases validation and calibrations.
