„ Big Ball of Mud“-Pattern In computer programming, Big Ball of Mud is a term for a system or computer program that has no real distinguishable architecture. It usually includes more than one of the other anti-patterns.
All too often reality Maintaining a shantytown is labor-intensive and requires a broad range of skills. One must be able to improvise repairs with the materials on-hand, and master tasks from roof repair to ad hoc sanitation. However, there is little of the sort of skilled specialization that one sees in a mature economy.
All too often reality All too many of our systems are, architecturally, little more than shantytowns. Investment in tools and infrastructure is too often inadequate. Tools are usually primitive, and infrastructure such as libraries and frameworks, is undercapitalized. Individual portions of the system grow unchecked, and the lack of infrastructure and architecture allows problems in one part of the system to erode and pollute adjacent portions.
An Architecture May Conform to an Architectural Style
Every well-structured software-intensive system is full of patterns. (Booch 2009)
An architectural style defines a family of systems in terms of a pattern of structural organization. More specifically, an architectural style defines a vocabulary of components and connector types, and a set of constraints on how they can be combined. (Shaw 1996)
An Architecture is influenced by its environment
Architecture is not concerned with a system‘s fine grained structures and elements (i.e. classes, objects, algorithms) but instead with such system‘s coarse-grained components and building blocks
“ The software architecture of a program or computing system is the structure or structures of the system, which comprise software components, the externally visible properties of those components, and the relationships among them ” [Bass et al]
