Let’s illustrate the concept of modules by an example. Assume there’s a requirement for a rich-client application to perform an auto-update process. This requirement during the design process will become the application’s responsibility. If we assign it to an Auto-Updater Module, it will mean that fulfillment of this responsibility lies solely with this module. Not-modular approaches often lead to scattering responsibility among so-called “modules” like “model”, “database”, “infrastructure”, “domain”. But in the modular approach, if it’s decided that auto-update is not needed anymore, we should be able to get rid of this responsibility by deleting just one module (and its wiring to other modules), without the need for the shotgun surgery throughout layers.
Turbulence is the ghost in the attic of air travel—the bump and shake and rattling groan that we do our best to ignore, though it sounds like it wants to kill us. Most of the time, it hovers over mountains and in storm clouds, easy enough to avoid. Pilots can see bad weather lurking in the distance hours before takeoff, glowing like a wraith on their digital maps. If it moves, the plane’s radar can still spot it eighty miles ahead or more. But the updraft that struck Flight SQ321 was of a more sinister sort. Although it came from the storm clouds below, there was seemingly no rain in it for radar beams to reflect against. It was like an invisible speed bump in the sky.
