  1. In a database
  2. Set up databases, write server-side code, optimize server-side code to handle scale, bugs, efficiency and security.
  3. A group of server-side applications. LAMP for example which is Linus, Apache, MySQL and PHP program languages.
  4. NodeJS, Flask and Django.
  5. Because it is written in server-side Java Script which is also a front end language and requires learning one less language since you can use Java Script for both front and back end programming.

Back-end Technologies – Reading Assignment

1. How does a back-end application normally store information?

On a server from a database.

2. Name a few things back-end developers need to do.

  • Writing server-side code

  • Writing code to interact with a database

  • Ensuring that the server-side code is secure and free of vulnerabilities

  • Ensuring that the server-side code is optimized enough to handle large volumes of traffic

  • Deploying the code online so that other people can use your service

3. What is a technology stack?

Technology stack is the combination of programming languages, tools and frameworks that the developers use to create web and mobile applications. A stack is created when one layer of application is built atop the other.

A stack contains different layers of components/servers that developers use to build software applications and solutions.

4. Name a popular back-end stack.

The back end consists of a server, an application (OS, Web server, Programming language, Web framework), and a database.

An example would be:

LAMP is the abbreviation for Linux, Apache, MySQL and PHP. Linux is the server operating system, Apache is the web server, MySQL is the database and P is for PHP, the scripting language.

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

NodeJS is a JavaScript server-side framework. JavaScript is also used on the client-side, so you have a single language over the entire application (assuming you’re building a web app).

1 Usually as a data base, or document repository but other types of file also (maybe encryption and firewall settings?
2 Ensure dat is in the correct format, usable Secure up to date and recoverable in the format the APO needs it to be in.
3 The Technology stack is the different components of the system; the Server (My SQL) the operating system and language for the server and the API.

4 LAMP

5 Same or very similar language for front and back end development at least up to a point.

    Backend developers need to know what a database is and the different types of databases available.
    Backend developers should gain an understanding of http.
    They should also know what an API is and the different types of API.

  3. A technology stack is a combination of operating system, server, database and server side language or a framework which helps the different elements to communicate with each other.

  4. A popular back end stack is Django

  1. A backend application normally stores information in a database.
  2. Backend developers could write server-side code, write code to interact with database, ensure security of server side code, optimize server-side code to handle large volume of traffic, and deploy code online for other people to use the service.
  3. The technology stack refers to a set of backend technologies.
  4. A popular backend stack is the LAMP, which comprises (a) Linux OS, (b) Apache server, © MySQL database & (d) PHP (server-side language).
  5. NodeJS is popular because it’s a server-side JavaScript framework. And if you already know JavaScript (a client-side language), you could spend less time learning the backend.

How does a backend application normally store information?

  1. A backend application normally stores persistent information in a database.

    Name a few things backend developers need to do.

  2. They need to manage know server side languages and frameworks to build the application. They need to version development code, code api’s and db calls, fix bugs, deploy into test and production environments and sometimes understand how the server resources are loaded to keep the application up.

    What is a technology stack?

  3. A technology stack is composed of data and process layers comprising a full application solution.

    Name a popular backend stack.

  4. For example, LAMP (Linux, Apache, MongoDB and PHP) is one stack example.

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

  5. Because it utilizes a common language, javascript.

#13
  1. Within a server/database.
  2. Write server-side code including code to interact with a database. Deploy the code.
  3. A set of backend languages used for backend development.
  4. LAMP
  5. Because there is only one language that you need to learn for both frontend and backend.

  2. Name a popular backend stack.
    Django

  3. Why is NodeJS convenient for front-end developers who want to start programming backend?
    It utilises JavaScript in both client side and server side development, this removes the need to learn a new programming language to develop the full application.

    JavaScript.

  3. Why is NodeJS convenient for front-end developers who want to start programming backend?
    Since JavaScript is also used on the client-side (frontend) you have a single language over the entire Application when building a web app. you have one language less to learn.

#19

  • How does a backend application normally store information?
    In a database

  • Name a few things backend developers need to do.
    Design the database tables/fields/functions
    Create a structured data stack that provides organized code (data services, business logic, expose public and private APIs, authentication, identity and session management

  • What is a technology stack?
    It’s the interaction of differing technology choices. For example:
    SQL Server Database paired with Microsoft .Net MVC for the code/frontent

  • Name a popular backend stack.
    MongoDB / NodeJs

  • Why is NodeJS convenient for front-end developers who want to start programming backend?
    Because it’s essentially javascript. When paired with MongoDB, the consistency between the javascript frontent, the javascript server-side code and the JSON database makes it really consistent and easy.

#20

  1. Backend application normally stores information in database within the server.

  2. Things backend developers do include:

  • Write server-side code
  • Write code that interacts with database
  • Ensure server-side code is secure by using best practice and protection solutions e.g. encryption, access control, infrastructure security
  • Ensure server-side code is optimised to handle large volume of traffic
  • Deploy code online for users

  1. A set of backend technologies essential to build backend application, such as operating system, server, database and server-side language. A classic set of technology stack is: LAMP (Linux, Apache, MySQL, PHP). Modern technology stack is moving toward frameworks written in popular languages like Python and JavaScript: e.g. NodeJS (framework), Amazon Web Services (saas), MLab for MongoDB (daas), JavaScript (server-side language which is also a frontend language).

  2. NodeJS, Flask, Django.

  3. Because NodeJS is a backend framework that is written in JavaScript, which is the same language many frontend developers already use in frontend end development. This means one language for both front and back ends.
