When talking about software architecture, there are a few key concepts that come up over and over. These concepts include modularity, abstraction, layering, and separation of concerns. Let's take a look at each of these concepts in turn.
Modularity is the idea of breaking a large system into smaller pieces that can be independently developed, tested, and deployed. A good example of modularity is the way that most web applications are built using a front-end (what the user sees and interacts with) and a back-end (where all the data is stored and processed). This separation allows different teams to work on different parts of the application without having to worry about stepping on each other's toes.
Abstraction is the process of hiding complexity from the user. A good example of abstraction is an API (Application Programming Interface). An API exposes only the functionality that a developer needs to use, while hiding all of the underlying implementation details. This makes it much easier for developers to use someone else's code without having to understand everything about how it works.
Layering is another way of dealing with complexity. When you layer your software, you break it down into different levels, with each level providing services to the level above it. For example, in a web application you might have a presentation layer (the part that generates HTML), a business logic layer (the part that contains all your application logic), and a data access layer (the part that talks to your database). By breaking things down into layers like this, you make it easier to develop, test, and deploy your software.
Separation of concerns is another important concept in software architecture. It simply means keeping different parts of your code independent from each other so that changes in one area don't affect other areas. For example, if you're building an e-commerce website then you might want to keep your shopping cart code separate from your payment processing code so that changing how one works doesn't break the other.
These are just a few of the key concepts that come up when talking about software architecture. By understanding and applying these concepts, you can build better, more maintainable software.
