    The beauty lies in layers. Grouping similar functionalities into layers has proven to be one of the most reused patterns in the whole information technology domain, and wider. Not only software, but also whole company's information technology infrastructure is often built with layered design applied. We emphasize a few of the most important IT middleware subsystems and illustrate why layered desig... View full abstract»
