For a long time, the biggest headache for software developers had to deal with disorganized codes and unstructured layers. In an overview, you might think that the traditional database cantered design is comfortable and not difficult to follow but wait until you have a clear picture of all the paths you need to pay attention to.
The traditional way of software development was very much inclined to extra smart developers who did not mind taking long to code and decode data. However, recently, we welcomed the new age of developers who want to find the most natural way around so that more work can be done in less time. This is how to clean software architecture came to light.
The Roots of Clean Software Architecture
First introduced by Robert C. Martin, commonly known as Uncle Bob, the clean software architecture focused on clean codes which makes it easier for software developers to archive business agility for different companies regardless of the industry. Bob's version was, however, not necessarily the first clean architecture to come into the limelight.
By the time he was launching his architecture in 2011, other models such as Hexagonal, Onion, Screaming, DCI and BCE architectures were already using the same insight. Nevertheless, Uncle Bob saw it fit to make the secret clearer by introducing clean software architecture. This was when most software developers gained more insight into how and why the other architectures that used the clean code secret were better in development models and easier to use. All models that use this secret may differ in details, but they all seek to utilize one important principle; Separation of concerns.
Separation of Concerns Explained
Being in line with the principle of separation of concerns mandates that one should have a system which archives the following characteristics:
An independent user interfaces
One can easily change a website's or application's UI without having to change the rules of business. A UI console makes this possible and fast.
Independent frameworks make it possible for you to consider frameworks as tools that can be used independently. This prevents you from overwrapping your systems with unlimited constraints.
How easily can your software be tested without having to include the UI, Server, and database?
An independent database
A database does not have to be the center of your development. Freedom is being able to migrate from SQL to Oracle without affecting your business rules.
Independent external agencies
How well can your business run without being affected by the external world? How well can your software function without external disruptions?
Clean software architecture merely is flexible, adaptable, and easy to maintain. With the five features above, you not only have it easy when developing your software but also when you are seeking to upgrade or run a different software project. This reduces costs and makes better use of available resources.
Defining the Dependency Rule
With clean software architecture, there is one significant rule that describes all its policies. The dependency rule simply says that the all source code dependencies can only lead inwards. This means that the inner circle is strictly allowed to lead its own and not outwards. Anything declared in the outer ring cannot be mentioned in the inner circle, whether a class, a function, variable, or any other entity. In the same case, data formats and tokens in the outer ring should be duplicated in the inner circle. This keeps the outer circle independent of the inner circle and vice versa; thus, external security issues are not spread internally.
Clean Code and Its Benefits to Software Developers
Some bad codes do work and more so for a significant amount of time until an issue has to be corrected, and developers realize that resources and time needed to clean up the mess could have otherwise been channeled to other productive aspects of development. To prevent such casualties, it is time to introduce clean code from the word go. This will challenge you to make use and advance your professionalism by understanding code in depth. The best thing is that with clean software architecture, a plan is laid out already, making work easier and faster.
When putting down a clean code, you need to describe its practices, principles, and patterns. Afterward, you will need to undertake several case studies to clean up codes previously used. This will help you tackle problems faced by previous codes, thus increasing efficiency. Finally, you will then usher yourself into the pay off stage as described by Uncle Bob.
In summary, to create clean code, you will need to know the difference between clean and bad code, how to write clean code and how to transit from lousy code to clean code. You also need to be conversant with clean code's names, functions, objects, and classes. Soon you will then be able to arrange code that has maximum readability and handle errors, after testing. All this can be found on Uncle Bob's book on clean code, and we at Ignite can do all the background work for you, plus offer free consultancy.
Clean Code And Its Benefits To Customers
The beneficiaries of clean software architecture are not limited to software developers and experts alone; the advantages can be enjoyed by customers too. This is because of the well-designed and structured software systems. This “single” benefit gives rise to several other benefits consumers stand to enjoy from this method of system design.
The advantages include:
One of the most known facts about clean architecture is that the software is produced with as little bugs as possible. This is because the systems are properly structured and bugs are easily located and taken care of during the testing process.
The clean software architecture lowers the maintenance, adaptation, and upgrade burden. Since user expectations are always evolving, there is a need to constantly upgrade the software systems in order to maintain their efficiency in the long run. Systems that are easy to scale and adapt to end-user demands are always highly sought-after. Using clean architecture, the quick adjustments or upgrades can be done easily and efficiently with no influence on the modules that are working just fine.
Basically, the clean software architecture only requires you to follow a few simple rules which will eventually lead to a hassle-free developing and code writing experience. With software layers and the dependency rule, everything is a matter of duplicating steps only with more specified codes that work for your desired results. The system will be easy to test, correct, and advance, plus other benefits stated in the article. Efficiency will not be of any concern as all steps make sure that this is looked into from all angles. In the future, when the database, UI, or frameworks become obsolete, you can easily change them without affecting the inner circle. Business rules remain untouched unless you decide to advance them as well. This is the epitome of business agility, where everything is easily scalable, and the most critical aspects of the software remain secure and firm.
