4. Three-level structure
Three-tier architecture often divides client-server applications into three logical and physical computer layers.
The three tiers consist of the application tier, presentation tier, and database tier.
Frontend Web Frameworks vs Backend Web Frameworks
Frontend and backend are two of the most important terms in website development. Both are important in web development, but they are very different.
Front-end and back-end platforms work in tandem to improve website performance.
Front-end web frameworks
In web development, front-end development rcs data israel refers to the visible portion of a website. Also known as CSS frameworks or client-side frameworks, they are pre-written packages of code that developers can use as a base. Front-end frameworks typically provide a grid to organize design elements, preset font styles, and ready-made components such as buttons, panels, etc.
The front-end, also known as the front-end, consists of all the parts that present the online application to the user in the browser - everything the user sees in the web application or web page. HTML, CSS, JavaScript or JQuery are used to create the front-end.
The front-end framework provides basic templates and components for building the front-end of a web application, with an emphasis on the functionality and interactivity of the application.
A front-end framework can contain components for structuring files, developing the entire user interface (UI) and user experience (UX) , applying themes or using components with unique styling, and optimizing for SEO, performance, or scalability.
Internal web frameworks
Back-end web frameworks, also known as server-side web frameworks, help in building web applications.
Server-side platforms provide tools and libraries that simplify basic web development tasks, such as user authentication, URL routing, database interaction, push notifications, and security enhancements. Unlike front-end frameworks, everything happens on the server and is invisible to the user.
The backend, or server side, refers to everything that resides on the server; the background function of a web application.
The backend components include a database, web server, operating system, infrastructure, and server-side programming languages such as Python, PHP, .Net, Swift, Objective-C, JavaScript, Ruby, Kotlin, C#, C++, GO, and Dart.
Backend platforms provide tools and components to handle database manipulation, user authorization, security and privacy features, URL routing, and output formatting.
