Separation of Concerns Principle
Separation of concerns is the core principle connecting the previously discussed components. It ensures that each part of an application has a single, clearly defined responsibility.
Clear Responsibility Boundaries
Each component focuses only on its designated task, such as models handling data and views handling presentation. No component attempts to perform another’s role, preventing overlap and tight coupling.
Maintainability and Scalability
This structure makes applications easier to maintain and extend. Changes to one layer, such as the database or user interface, can be made with predictable and limited impact on other parts of the system.
Now that we have covered the three parts individually,
I want to talk about the principle that ties everything together,
which is separation of concern.
Separation of concerns means that each part of the application
has one clear responsibility.
It doesn't try to do someone else's job,
which means that our model doesn't try to render a view,
or a view doesn't try to fit something from the database.
They only focus on the specific tasks that we have clearly outlined
in the last three videos.
So this really matters because it makes our system,
our application much easier to grow and to maintain.
We can redesign certain elements without affecting
or making changes that we are not aware of,
because we know that if we change, let's say,
our database structure, it's going to affect our models.
We also know that we can change how our views
are going to affect our models.
So we can change how our views are going to affect our models.
So we can change how our views are going to affect our models.
