Software architecture is a ___ for a system

It provides an abstraction to manage the system complexity and establish a communication and coordination mechanism among components.

Most traditional and oldest architectural pattern

• OBJECT-ORIENTED
• CLIENT-SERVER
• LAYERED

You start with a big problem and decompose it into several smaller, semi-independent problems

• SUBROUTINE
• PIPE-AND-FILTER
• OBJECT-ORIENTED
• CLIENT-SERVER
• LAYERED

Solves the problem from the top down, and write the code from the bottom up

Has computational components called filters

• SUBROUTINE

Filters act as transducers that take input, transform it according to one or more algorithms.

Won't work so well for interactive applications

• SUBROUTINE

• OBJECT-ORIENTED
• CLIENT-SERVER

The Model-View-Controller (MVC) architectural pattern breaks an application into three parts: the model, the view, and the controller.

The main idea is separation of concerns--and code
