Technical debt encompasses various design and implementation decisions that may optimize for the short term at the expense of future adaptability and maintainability. It has been defined as "a collection of design or implementation constructs that make future changes more costly or impossible," primarily impacting internal system qualities such ...
Instead, they indicate weaknesses in design that may slow down development or increase the risk of bugs or failures in the future. Bad code smells can be an indicator of factors that contribute to technical debt. [1] Robert C. Martin calls a list of code smells a "value system" for software craftsmanship. [7]
Martin Fowler (18 December 1963) is a British software developer, [2] author and international public speaker on software development, specialising in object-oriented analysis and design, UML, patterns, and agile software development methodologies, including extreme programming. His 1999 book Refactoring popularised the practice of code ...
Martin Fowler defines a pattern as an "idea that has been useful in one practical context and will probably be useful in others". [2] He further on explains the analysis pattern, which is a pattern "that reflects conceptual structures of business processes rather than actual software implementations". An example: Figure 1: Event analysis pattern
Fowler calls such external classes transaction scripts. This pattern is a common approach in Java applications, possibly encouraged by technologies such as early versions of EJB 's Entity Beans , [ 1 ] as well as in .NET applications following the Three-Layered Services Application architecture where such objects fall into the category of ...
The name Specification by Example was coined by Martin Fowler in 2004. [ 9 ] Specification by Example is an evolution of the Customer Test [ 10 ] practice of Extreme Programming proposed around 1997 and Ubiquitous Language [ 11 ] idea from Domain-driven design from 2004, using the idea of black-box tests as requirements described by Weinberg ...

According to Martin Fowler, the hexagonal architecture has the benefit of using similarities between presentation layer and data source layer to create symmetric components made of a core surrounded by interfaces, but with the drawback of hiding the inherent asymmetry between a service provider and a service consumer that would better be ...
