Nowadays, having a website has become essential for a business. Consumers are increasingly choosing to search and choose the product on websites for the amenities it offers. It is essential for a company to have a virtual point where they can make their services known to potential clients.
However, before entering the subject, it is convenient to make a distinction between the definition of frontend technologies and backend technologies.
We understand frontend technologies to the set of technologies that function and work on the client side. On the contrary, backend technologies are those that work and operate on the servers side. Currently, some of the languages that can be found in terms of web development are the following.
- HTML5: It is the main technology used to structure the contents on the web, standardized by w3c. It is a mark-up language that allows you to create the structure and elements of a web that will later be interpreted by browsers.
- CSS: Its function is to describe how the HTML structures must be visually represented. HTML was created to describe the content on web pages, CSS defines the visual styles that content will have. Combining HTML and CSS in two separate files, it is possible to separate the content and the presentation of a web in a clear and organized way, facilitating the work of the developers.
The most popular backend languages in the last year have been the following based on typologies:
- Functional languages: Elixir, Scala, Java, Clojure.
Depending on the language there are different frameworks that allow large-scale development, the most popular at present are:
- Phoenix (Elixir)
- Ruby on Rails (Ruby)
- Django (Python)
- Flask (Python)
- Spring Boot and Spring Cloud (Java)
The most used databases based on their typology are Relational (MySQL, MariaDB, PostgreSQL, Oracle) and NoSQL (MongoDB, Cassandra, CouchBase, RethinkDB, Elastic Search, Neo4j).
