  1. Within a database.

  2. Backend developers need to do:
    -write server-side code

  • write code to interact with database
  • ensuring that the server side code is; - secure and free of vulnerabilities
    - optimised enought to handle large volume of traffic
  • deploying the code online so that other people can use your service

  1. programming languages, tools and frameworks to create a web and mobile applicatioin by the developer.

  2. 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

1. How does a backend application normally store information?
On a server

2. Name a few things backend developers need to do.
Write server side code, database programming, deploying code

3. What is a technology stack?
A group of coding programs used for a particular purpose such as a front end stack

4. Name a popular backend stack.
LAMP stack - Linux operating system, the Apache HTTP Server, the MySQL relational database management system, and the PHP programming language.

5. Why is NodeJS convenient for front-end developers who want to start programming backend?
NodeJS is a javascript server side framework. Most front end developers use javascript so using Node for the backend means we only need to use and learn 1 language.

  1. How does a backend application normally store information? On a Database
  2. Name a few things backend developers need to do. Bugfree servers, code to interact with Database, watch possible vulnerabilities in the code!!!
  3. What is a technology stack? is a set or a stack of backend technologies, like LAMP (Linux (OS), Apache (Server), MySQL(Database), PHP (Server Side Language)) or new technologies that replacing LAMP like the ones written in Python and JavaScript like Flask.
  4. Name a popular backend stack. Flask, Django…
  5. Why is NodeJS convenient for front-end developers who want to start programming backend? Because you can use it for the backend but also for the front end, in some way one less language tolerant!!!

1 on databases.
2 Writing server-side code, writing code to interact with a database, deploying the code online so that other people can use your service.
3 Different technologies and programming languages you need to utilize.
4 Lamp ( Linux, Apache, MySQL PHP)
5 Because it is a front end language that you may already know, so you just need to understand the backend framework.

  1. In a server which contains a database. Now cloud services are very popular for backend purposes with aws, google cloud and azure providing server as a service. Inside these servers or cloud services you have nosql and sql databases which store the information.

  2. They have to code the data model into relational or non relational databases in a secure and optimized way that allow to retrieve the information very fast. This involves also the code that allows interaction with the database.

  3. A set of technologies that are neccesary for the backend to work, including operating system, server configuration, programming languages for communication, and databases.

  4. Cloudera, hadoop, hive, spark.

  5. Because it is javascript language which is also employed in front end development.

  1. How does a backend application normally store information?
    Information is stored in a number of ways but can be abstracted as a ‘Datasource’

A ‘persistent’ data source might be a database such as MySQL or a graph. or messaging services such as Kafka or RabbitMQ or simply writing a file in a platform-agnostic format such as JSON

A ‘cache’ Datasource is a data source where the information is not ‘persisted’ but kept in the computer’s memory. Redis or Memcache for example. This type of data source has faster access time but the information will be lost if the application goes down

  1. Name a few things backend developers need to do.
    Architecting systems, Data modelling, programming algorithms and data structures. Testing of various forms, security modelling and implementation core security components. Database development, messaging, event modeling.
  2. What is a technology stack?
    The stack is the collection of infrastructure, tools, frameworks and api’s used in the full software development lifecycle of an application (SDLC)
  3. Name a popular backend stack.
    Lately, the core stack I use is Java with Spring framework and some DB or messaging service.
  4. Why is NodeJS convenient for front-end developers who want to start programming backend?
    because it means they don’t have to learn a new language.

  1. Backend applications normally store information in a database application such as SQL.

  2. Backend developers need to write server side code, write database side code to query the database, streamline access to data, work with front end developers.

  3. A technology stack is that group of developer tools that are used to manage the back end.

  4. A popular back end stack is called LAMP. Linux, Apache (server), MySQL (database), PHP (server-side language)

  5. NodeJS is convenient for front end developers because its Java Script for the back end which is also used on the front end. Therefore developers have one language for writing code on front and back end.
