Study Notes
Model-View-Controller (MVC)
- MVC is a design pattern used for building web applications.
- Divides application into three interconnected components: Model (data), View (user interface), and Controller (business logic).
Object Relational Modelling (ORM)
- ORM connects database tables to programming classes.
- Facilitates database interaction by representing database tables as classes, columns as properties, and rows as objects.
- Enables queries to be executed as methods.
- Most modern web frameworks, including Django, utilize ORM principles.
Web Frameworks
- Frameworks are often language-specific, intending to simplify development.
- Commonly used frameworks include:
- Python: Django
- Java: Spring
- PHP: Laravel
- Ruby: Ruby on Rails
- Two primary types of web frameworks:
- Server-Side: Django, Ruby on Rails
- Client-Side: Angular, React, Vue
- Focus on server-side frameworks for Web Application Development (WAD).
Setting Up Django
- Create a new folder for the project.
- Navigate into the folder and ensure that Python 3 is installed.
- Install Django using:
pip3 install djangoorpip install django.
- Start a new Django project named "hello_django":
- Use command
django-admin startproject hello_django.
- Use command
- Change into the project folder using
cd hello_django. - Run the server with
python manage.py runserver. - Access the web application via
http://127.0.0.1:8000.
HTTP Protocol
- HTTP is fundamental for server communication, allowing retrieval of HTML, images, and documents.
- Supports methods for CRUD operations:
- Create: POST
- Read: GET
- Update: POST (edited data)
- Delete: DELETE
Dynamic Websites
- Dynamic websites can update content through a Content Management System or a database.
- Enable easier updates, such as catalog prices or news announcements.
- Can integrate with other systems for functionalities like e-commerce and booking.
API and Backend Connection
- APIs serve as the connection layer between the frontend and backend.
- Utilize API calls (POST, GET, PUT) to transmit data, usually in formats like JSON.
- Service architecture governs application logic and data handling.
Web API Characteristics
- Must emphasize usability and compliance with standards (response codes, etc.).
- Attention to security and API version management is crucial.
- RESTful API design principles should be followed to ensure standardization.
