Some famous patterns are: There are famous 26 design patterns divided into three categories: Includes Abstract Factory, Builder, Factory Method, Object Pool, Prototype and Singleton pattern. 3. These are general solutions to general problems which have been proven from the experience of many programmers. For example, “what classes will we have and how will they interact, in order to implement a system with a specific set of layers“, or “what high-level modules will have in our Service-Oriented Architecture and how will they communicate“, or “how many tiers will our Client-server Architecture have“. Architectural vs. design patterns. ); How to make an object behave differently according to its state (maybe a state machine, or a Strategy Pattern?).

In general (switch off your inner programmer for some time) the architecture and design both explains the 'idea' but Architecture focus on the abstract view of idea while Design focus on the implementation view of idea. Patterns and Arch. Architectural Patterns have an extensive impact on the code base, most often impacting the whole application either horizontally (ie. how a request is processed from the outer layers into the inner layers and back). These patterns should obey your program, not vice versa. In them, I write about what I’ve learned on Software Architecture, how I think of it, and how I use that knowledge.
