The design pattern types are usually split across three broad categories: creational, structural and behavioral. Let's for example consider you are working on a complex classification problem. It is not a finished design that can be transformed directly into source or machine code. Flame Stitch. It is a description or template for how to solve a problem that can be used in many different situations. Patterns address common UX issues seen across websites, so designers don't need to invent a solution to the same problem over and over again. This isn't an exhaustive list of Design Patterns and App Architectures or an academic paper. They are categorized in three groups: Creational, Structural, and Behavioral (for a complete list see below). 1.
