Structure of the web application

 The structure of the application is responsible for how its individual elements are built and how they communicate with each other. Two terms appear most often here:

  • Front end - this is the part that end user sees. The front end is based on code written in HTLM,CSS or JavaScript and is stored in the browser. This is where all internaction with user take place (loggig in,handling,sending inquiries,etc.).
  • Back end - is the partthat remains invisible from the end user's perspective. Here,the main role played at the server,which communicates with the database and responds to commands sent by the user,which are then executein front end.The sever part most offten created in languages such as Java,PHP,Ruby or Python. (Codecademi, 2021) 



Application architecture:

  • Database layer - store all the data that the application uses. This layer is also responsible for they safety,
  • Data access layer - provides access to stored data.
  • Business logic layer - specifies the logic and rules that govern application. This layer processes commands from the browser,executes the comments set and then sends the result to the presentation layer.
  • Presentation layer - here we will get to the front end. Everything users sees and does happens in this layer. (Fritzegar,2021)
