Web Development: Advanced Front-End and Back-End
Chapter 1: Introduction to Advanced Front-End and Back-End Web Development
In today\’s digital age, web development has become an essential skill for individuals and businesses alike. Whether it\’s creating a website for personal use or building an e-commerce platform for a company, the demand for skilled web developers is on the rise. This chapter will provide an in-depth overview of advanced front-end and back-end web development, focusing on the Grade 10 Computer Science curriculum.
Section 1: Understanding Front-End Development
Front-end development refers to the creation of the user interface and user experience of a website. It involves using HTML, CSS, and JavaScript to design and build visually appealing and interactive web pages. Students will learn the fundamentals of HTML, including creating elements, adding attributes, and organizing the structure of a webpage. They will also explore CSS, which allows for the customization of styles, layouts, and animations. Additionally, JavaScript will be introduced as a powerful scripting language that enhances the functionality of web pages.
Example 1 (Simple): Create a basic webpage using HTML and CSS to display text and images.
Example 2 (Medium): Build a responsive website using media queries and CSS grid to ensure optimal viewing experience on different devices.
Example 3 (Complex): Develop a dynamic web application using JavaScript frameworks such as React or Angular to create interactive components and manage state.
Section 2: Exploring Back-End Development
Back-end development focuses on the server-side of web development, handling database management, server configuration, and server-side scripting. Students will delve into the world of back-end programming languages such as PHP, Python, or Ruby. They will learn how to interact with databases, perform CRUD (Create, Read, Update, Delete) operations, and handle user authentication and authorization. Additionally, students will gain an understanding of server-side frameworks and libraries that expedite the development process.
Example 1 (Simple): Create a basic contact form using PHP and store user input in a MySQL database.
Example 2 (Medium): Build a blog website with a content management system (CMS) using Python and Django to allow users to create, edit, and delete posts.
Example 3 (Complex): Develop an e-commerce platform using Ruby on Rails, integrating payment gateways, user reviews, and real-time inventory management.
