Django and SQLite

• Django is a high-level web framework written in Python that follows the model-view-controller (MVC) architectural pattern. It simplifies the process of building web applications by providing a collection of tools and libraries for handling common tasks. One of the key features of Django is its built-in support for working with databases, including SQLite.

• SQLite is a lightweight, serverless relational database management system (RDBMS) that is included with Django by default. It is widely used, especially for small to medium-sized applications, because it is simple to set up and requires minimal configuration. SQLite stores the entire database in a single file, making it easy to manage and deploy.

• When using Django with SQLite, you can define your database schema using Django's object-relational mapping (ORM) layer. The ORM allows you to define your data models as Python classes, which are then mapped to database tables. You can perform database operations such as querying, inserting, updating, and deleting records using Django's ORM, without writing raw SQL queries.

• To configure Django to use SQLite, you need to specify the database settings in your Django project's settings file (`settings.py`). By default, Django uses SQLite and provides a default configuration that works out of the box. However, you can customize the settings if needed, such as specifying a different location for the SQLite database file.

• Here's an example of the minimal database configuration for SQLite in Django's `settings.py`:

    DATABASES = {

        'default': {

            'ENGINE': 'django.db.backends.sqlite3',

            'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),

        }

    }

• In this example, `'ENGINE': 'django.db.backends.sqlite3'` specifies the SQLite database engine, and `'NAME': BASE_DIR / 'db.sqlite3'` indicates the path where the SQLite database file will be created. The `BASE_DIR` is a variable that represents the base directory of your Django project.

• Once the database configuration is set up, you can create, migrate, and interact with your SQLite database using Django's command-line tools and ORM methods.

• It's worth noting that while SQLite is a suitable choice for development and small-scale applications, it may not be ideal for high-traffic or large-scale projects that require concurrent access to the database. In such cases, you might consider using more robust database systems like PostgreSQL or MySQL with Django. However, Django's ORM provides a consistent interface across different database engines, allowing you to switch databases easily without changing your code significantly.
