Significance of design patterns

The previous sections introduced two complementary approaches to software design – APIE and SOLID concepts. It has begun to crystallize that having code in a transparent form can be beneficial for a variety of reasons, because every programmer often, if not always, faces the challenge of designing a piece of code that extends or modifies existing ones.

One wise man once said, “The way to Hell is the path of continual technical debt ignorance....” Anything that slows down or prevents the development of applications can be considered a technical debt. Translated into a programming language, this would mean that even a small part matters, if not now, then later. It also follows that code readability and purpose are crucial to application logic, as it is possible to verify various hypotheses (for example, application operation).

The inability to perform business-oriented application testing can be considered the first sign of incorrect development trends. It may appear to require the use of different mock-up techniques during verification. This approach can easily turn into providing false-positive results. This can usually be caused by the clutter of the code structure, which forces programmers to use mocks.

Although the SOLID and APIE concepts suggest several principles, they still do not guarantee that the project code base will not start to rot. Adherence to these principles makes it difficult, but there is still room because not all concepts provide the required framework for dealing with rot.

There may be long stories of how software can rot over time, but one fact that remains is that there is a cure for avoiding it or letting it go. The cure is covered by an idea called design patterns. The idea of a design pattern not only covers the readability of the code base and its purpose but also advances the ability to verify required business hypotheses.

What are the ideas behind defining it to get more clarity? The design pattern idea can be described as a set of reusable coding approaches that solve the most common problems encountered during application development. These approaches are in line with the previously mentioned APIE or SOLID concepts and have an incredibly positive impact on bringing transparency, readability, and testability to the development path. Simply put, the idea of design patterns provides a framework for accessing common challenges in software design.
