  1. A backend application normally stores information in a relational database such as MySQL or some other type of centralised data store
  2. Backend developers need to write and test server-side code to provide services to the clients and update their data store(s), ensure the code isn’t vulnerable to attack, deploy the code to a commonly available platform and ensure it can handle the workload (i.e. That it’s ‘performant’.)
  3. A technology stack describes the set of technologies that need to be used, to deliver a working backend production service
  4. A popular backend stack is LAMP (Linux, Apache, MySQL, PHP)
  5. NodeJS is convenient for front-end developers who want to start programming backend, because it’s the same language that’s used (Javascript)

  1. It stores information in a database in the server.

  2. Writing server-side code, which includes writing code to interact with a database, ensuring that the code is secure and free of vulnerabilities, and that the code is optimised enough to handle large volumes of traffic.

  3. It is the classic set of backend technologies that addresses the server, the database, the operating system and the server-side language.

  4. LAMP for Linux, Apache, MySQL and PHP.

  5. This is because they can still use the same language Javascript and do not have to learn another language.

  1. Database

  2. Write a server code which includes code to interact with a database, ensure that the server side code is secure, optimize it enough to handle large values and then to deploy the code online.

  3. Is technology infrastructure, or a data ecosystem, is a list of all the technology services used to build and run one single application.

  4. Django, LAMP, NodeJS

  5. Because it is based over Javascript.

  1. How does a backend application normally store information?

In a database.

  1. Name a few things backend developers need to do.

Write secure and scalable server-side code. Come up with system architectures.

  1. What is a technology stack?

A technology stack is the set of technologies usually used for a specific purpose (like for example backend development).

  1. Name a popular backend stack.

The traditional backend stack was LAMP (Linux, Apache, MySQL and PHP). Then it was replaced by backend frameworks like Django, Flask or NodeJS. Also learning about a database like SQL or MongoDB is important. Most recently other more modern languages like Go are added to the backend stack of many.

  1. Why is NodeJS convenient for front-end developers who want to start programming backend?

Because with NodeJS you use JavaScript (which is usually used to write frontend) for the server-side code. This saves you the time of having to learn another language as you can use JavaScript for both frontend and backend.

1-The info or data is stored in a Data Base such as MySQL
2- They need to learn server side programming language (Python, C++, Java Script), servers (Apache , Oracle…) and data bases (SQL, My SQL…) and recommended knowledge on front end programming
3- A tech stack is the set of tools a developper needs to know and manage to programming either frontend, backend or both.
4- LAMP: Linux, Apache, MySQL, PHP
5- Because NodeJS is a Java script framework and JS is a language that can be used both in frontend and Backend programming.

In a database such as MySQL

  1. Name a few things backend developers need to do.

Interact with the Linux OS on the server.
Write code to interact with the database, typically MySQL, although there are other options.
Keep server-side code free of vulnerabilities and able to handle large volumes of interaction.
Deploying code online so that other people can interact with it.

  1. What is a technology stack?

In the context of development, a technology stack is the combination of different, standalone systems that all interact to create the desired result.

  1. Name a popular backend stack.

LAMP - Linux, Apache, MySQL and PHP. These are the OS, server, database and server-side language respectively.

  1. Why is NodeJS convenient for front-end developers who want to start programming backend?

It makes use of JavaScript, which was typically only a frontend development language before NodeJS.

Understand what http communication is.

Know what an application programming interface is (API).

Understand the difference between soap and rest APIs.

  1. What is a technology stack?

The classic set of backend technologies (the “technology stack”) is called LAMP. It is an acronym that stands for Linux (operating system), Apache (server), MySQL (database), PHP (server-side language).

  1. Name a popular backend stack.

Flask is a popular backend framework written in Python. However, the most well known and popular backend framework in Python is Django.

  1. Why is NodeJS convenient for front-end developers who want to start programming backend?

Name a popular backend stack.

A popular backend stack is LAMP

Why is NodeJS convenient for front-end developers who want to start programming backend?

NodeJS uses Javascript as a base. As Javascript can also be used to program backend functions, NodeJS enables back-end and front-end interaction using one programming language as a base
