The Layered Pattern – Software Architecture Solutions
We start our journey through software architecture patterns with one of the most common. The layered pattern is easy-to-use and often easy to understand. However, it is misunderstood, and there are challenges to overcome. These are not weaknesses of the pattern. Instead, they are obstacles for the designers and implementors to overcome. This approach is also known as an N-tier pattern. The Layered Pattern Defined This pattern is a divide-and-conquer approach to software architecture. The application is broken down into four layers that interact. Thus, a complex problem to be addressed as smaller problems. The four layers typically flow from the user to the solution’s back-end.
