Backend development usually refers to server-side programming when creating or engineering software applications. There are several types of backend development, they are referring to the web, mobile, desktop, custom scripting like API or even automation. In most cases when a person refers to back-end development it also usually includes some sort of database integration or programming. The easiest and simplest way to summarize what backend development is would be by stating it is the programming code and logic that provides advanced functionalities to a website without being seen or behind-the-scenes. There are several different languages available to perform backend development a few worth mentioning are:
· Personal Home Page (PHP)
· .NET (C#, VB)
As mentioned above, these are only a few languages that can be used in backend development and there are several more. The reason we mentioned the ones above is because of the popularity of the languages and more and more people are starting to adopting them. When it comes to backend development there are normally two approaches that are used one is the Object-Oriented Programming (OOP), and the other is Functional. Most backend developers tend to use the OOP method due to the requirements of the project, however, when dealing with most databases the functional method is used quite often. The difference between the two methods is OOP uses a structural approach meaning the object-oriented programming method must execute the statement in a specific order while the functional method can be executed in any order. It is more common to see the functional method be used in data sciences and database languages.
Back-end development has big importance especially in modern-day projects due to the involvement of customized interactions. To explain, if the is retrieving data from a database backend developer must establish a connection to the database and destroy that connection once the connection is used so it is not open all the time and using unneeded resources. The responsibility of making the system/software/application efficient as possible also usually falls on the backend developer because they can have more opportunities to optimize the logic and code to perform different tasks. This is not saying the frontend developer does not have any optimization responsibilities. Usually, backend development tends to be more challenging compared to frontend development mainly because of the logic that is involved while frontend development can be more tedious and creative challenges. This could be one of the reasons some people look into full stack development to get the best of both worlds and trust us it takes a lot of skill to be a good full stack developer because you have to be both creative and logical and those are completely opposite traits.
