Design patterns provide proven solutions to real world problems faced in software designs. The Repository pattern is used to decouple the business logic and the data access layers in your application.

In the first layer from the bottom, the logic layer is made out of standard (Si-FET) transistors, demonstrating how this design can integrate with existing technology. Crunching Big Data.

When the computer gets busy, the wires connecting logic and memory get jammed. A new approach would build layers of logic atop layers of memory to create tightly interconnected high-rise chips.
