Software architecture is one of the most critical aspects of software development, but it’s also tricky to get right. Many developers make common mistakes that can lead to big problems down the road. SCA tools can help by providing a way to enforce best practices and prevent common errors automatically. This blog post will discuss some of the most common mistakes developers make when creating software architecture and how to avoid them.
Not enough abstraction
One of the most common mistakes developers make is not enough abstraction. Abstractions are essential because they allow us to hide complexity and make our code more readable and maintainable. Your code can become very difficult to understand and change without proper abstraction.
One way to create better abstractions is to use design patterns. Design patterns are proven solutions to common problems that occur in software development. We can make our code more robust and maintainable by using design patterns.
Another way to create better abstractions is to use data structures and algorithms. Data structures and algorithms are the foundation of any software system. Using the proper data structure or algorithm can make your code more efficient and easier to understand.
Finally, we can also create better abstractions using the right technology stack. The technology stack is the set of tools and technologies that we use to build your software systems. By choosing the right technology stack, you can make your code more scalable and easier to maintain.
In summary, abstraction is essential because it allows us to hide complexity and make your code more readable and maintainable. We can create better abstractions by using design patterns, data structures and algorithms, and the right technology stack.
Not enough modularity
Another common mistake developers make is not enough modularity. Modularity is essential because it allows us to break your code into smaller pieces that are easier to understand and maintain. Your code can become very difficult to change and reuse without proper modularity.
One way to achieve modularity is to use design patterns. Design patterns are proven solutions to common software design problems. We can make our code more modular and easier to understand by using design patterns.
Overuse of inheritance
Inheritance is a powerful tool that can help us reuse code. However, it is essential to use inheritance wisely. Overusing inheritance can lead to problems such as a bloated class hierarchy and inefficient code.
It is important to remember that inheritance should be used to extend functionality, not duplicate it. If you find yourself duplicating code in our subclasses, we are probably doing something wrong.
Finally, we need to be careful when using multiple inheritances. Multiple inheritances can lead to the “diamond problem,” which can be very difficult to debug.

Ignoring the Single Responsibility Principle
The Single Responsibility Principle is fundamental in software engineering. It states that each module should have a single responsibility. This makes our code more maintainable because each module is only responsible for one thing.
However, many developers ignore this principle and try to cram too much functionality into a single module. This can lead to problems such as code that is difficult to understand and maintain.
It is important to remember that the Single Responsibility Principle applies not only to modules but also to classes and functions. Each class and function should have a single responsibility.
Poorly chosen data structures and algorithms
Another common mistake developers make is choosing the wrong data structures and algorithms. This can lead to poor performance and difficulty understanding the code.
It is vital to choose the proper data structure for the job. For example, if we need to store a lot of data, we might want to use a linked list instead of an array. If we need to perform many operations on the data, you might want to use a hash table instead of a binary tree.
Similarly, it is essential to choose a suitable algorithm for the job. For example, if we need to sort a large amount of data, we might want to use quicksort instead of bubble sort.
Choosing the wrong technology stack
Another common mistake developers make is choosing the wrong technology stack. This can lead to problems such as poor performance and difficulty understanding the code.
It is crucial to choose the right technology for the job. For example, if we need to build a high-performance system, we might want to use C++ instead of Java. If we need to develop an easy-to-understand and maintain the system, we might want to use Python instead of Perl.
Similarly, it is crucial to choose the correct database for the job. For example, if we need a relational database, we might want to use MySQL instead of MongoDB. If we need a NoSQL database, we might want to use Cassandra instead of CouchDB.
Finally, we need to be careful when using third-party libraries. Third-party libraries can make our code more complicated to understand.
