Have we ever wondered how to do this with a red button? Where is the info going? Do we need any more help to keep this data safe? What are some mechanisms to make the process disappear? It certainly does! It's called a backend. Nowadays we mainly utilize the internet in all of our activities. It has snatched everything we're doing from reservations and meeting people virtually through telephone conversations.
Tell me the difference between frontend and backend web development?
As a web developer you'll probably have heard about the LAMP stack before: Linux, Apache, MySQL, and PHP/Python/Perl. The first three form the operating system level while the last one stands for a programming language(s) often used for creating dynamic frontend applications - they require an enormous amount of memory and CPU cycles so using them on low-powered devices would be pointless. They're also not the most secure solutions out there which is why Nginx comes with a module called Memcached. It's a caching mechanism for web applications that reduces the load on MySQL and speeds up responses to users' requests by storing data required for rendering pages in memory instead of querying a database all the time.
Each type of application will require a different toolkit, but one thing that's always true is that you need quick access to data to show your customers that you're the master of the house. That is why we have SQL. What is it? It stands for Structured Query Language and isn't something new - it's been around since the 80s! However, this doesn't make it obsolete or "so old-fashioned" - on contrary, most programmers still use it today because it allows them to communicate with relational databases very quickly and easily. If you're really into developing web apps there is a great chance that sooner or later you'll have come across MySQL - supports all kinds of queries you can think of and is used by backend developers all over the world.
SQL stands for Structured Query Language, which was first created in... wait, let me check my browser history... 1982! It's still being used today because it's so convenient when it comes to querying relational databases.
The battle between frameworks goes on and on and can't stop since there's always something new created by either corporations or the open-source community. They all have different pros and cons so choosing the right one is incredibly important... but at the same time pretty hard as well! And now finally we come to what this article was about: SQL vs NoSQL. You'd think they both serve the same purpose, but they do not (well, sort of).
As you can see - knowing SQL is a must if you want to create Python or Node.js applications with a back-end system that uses data pools instead of NoSQL solutions. People who know SQL can easily adjust to any type of app later on since all they need is some time to learn the ins and outs of a new framework. And last but not least, most web apps rely on databases because their main purpose is serving as storage for users' information!

What is backend development?
It's the creation of a system (using any programming language) that stores and manipulates data for web-based or mobile applications. This process is done by creating "backend systems" that store and manipulates data. The backend development field requires back end developers to know both front-end and back-end technologies since they're all connected in one way or another!
SQL vs NoSQL: the final battle! Since NoSQL isn't a language, we can't compare it to SQL. With so many types of databases out there, it would be almost impossible to choose just one type and say: this is better than all others! That's why we'll focus on two of the most popular forms and see how they contrast with each other.
Front-end vs back-end development
As mentioned earlier, front-end development is the process of making a web/mobile app look pretty and function properly while back-end development is everything that goes on behind the scenes. With this in mind, it's easier to understand how important it is for full stack developers to know both NoSQL and SQL!
DocumentDB vs Graph DBs DocumentDB allows storing data as documents which means there are no predefined schemas - just put any data you want into fields that don't exist beforehand (you can do that with relational databases too). Storing data manually might seem hard at first but once you get used to it, your life becomes much easier since you can store anything anywhere! There are three types of operations supported by DocumentDB: create/read/update/delete. Or CRUD, as it is called everywhere! With Graph DBs you work with a schema and define relations between tables like: "this column points to that other one". This allows for fast writing and reading and makes the whole thing much more organized since we know what our data looks like even before we've created it! But on the other hand, these relations make writing complex queries harder since they must be handled by apps written in backend programming languages such as Java or C#.
What can we do with SQL?
As you might know, relational databases are the ones that support querying using SQL language (more details ). The most popular relational databases used and supported by all major back end programming languages include MySQL, PostgreSQL, and MSSQL. If you want to create a web app - use one of these databases since they're full-featured, well documented, and easy to use even for beginners. And last but not least - they offer high performance and reliability which is very important because apps such as these must be always up and running no matter what happens!
Should I learn frontend development or backend development?
Both are very important but it depends on your final goal. If you want to become a full-stack developer, then obviously you'll need to know both! Learning just backend or frontend development will make you be able to create either front-end or back-end solutions for web/mobile app projects. But since there are still many projects out there that require both (even if they're mostly used by small companies), learning them both will give you the upper hand in the job market no matter what form of development you choose in the end.
What's better - server-side languages or client-side languages?
Tell me the difference between front-end development and web design?
Web design is a broad term that includes front-end and back-end web development. It's everything that we do that lets users access the site we've created by inputting an address in their browsers. If you're going to learn just one of them - go for the front-end since it'll let you create both "design" and "functionality" parts of your website independently.
What tools should I use if I want to code for iOS?
All the same as those used when coding for Android! There are, however, slight differences between Objective C (used by Apple) and Java (used by pretty much everybody else). The main similarity lies in their programming languages: no matter which OS you choose - you'll need to learn C or C++ to create apps that work with the hardware. There are also cross-platform frameworks that allow you, in some cases, code just once and make it work on both Android and iOS (ex. Xamarin).
What's the difference between .Net and Java?
Similarities: both support object-oriented programming; their primary function is creating back-end systems; they require compiling before running; they're managed languages (more details ). Differences: .NET supports languages like C# while Java supports primarily JVM (Java Virtual Machine) based languages like Clojure, Groovy, Scala. Other than that - there are a few other differences if we don't take into account that Java is more often used in the context of mobile development while .NET is more often used for backend web development (and not always).
What's the difference between Android and iOS?
Android, like Windows, is an operating system which means that it gives you the ability to create apps that work on any hardware. You can't do that with iOS since it only works on Apple hardware. However - if you want your app to be available on both platforms at once (ex. cross-platform game) - use the Xamarin framework!
Can I code without knowing English?
Of course, you can! So long as your language uses alphabet characters (more details ) - it'll be enough to learn to program. If you're really bad in English but good in your native language (like Hungarian or Russian) - you can use programming tutorials in your language.
What backend skills are needed?
If you're planning on working with mobile apps, you'll probably need to know more than just the basics. If your app is going to rely heavily on backend functions (ex. analytics), make sure that you know how to use them! Basic knowledge of databases (MongoDB, MySQL) is also recommended if your app needs data storage/retrieval.
