Laravel Database Interaction

Laravel's Database Configuration

• The configuration for Laravel's database services is located in the config/database.php file.

Supported Database Systems

• MySQL and PostgreSQL are currently supported as first-party by Laravel.
• SQLite is also supported, but it stores the database in a single file on the filesystem.
• Microsoft SQL Server is supported, but requires the installation of specific database extensions.

Eloquent ORM

• Eloquent ORM provides a simple and elegant Active Record implementation for Laravel's database interactions.
• It allows for easy interaction with the database, providing a simple and intuitive API for creating and manipulating database records.

Development Tools

• Laravel provides Sail, a tool for developing applications on a local machine using Docker.
• Sail allows for easy setup and management of a development environment.

SQLite Database

• To create a new SQLite database in your terminal, use the command sqlite3 database.sqlite (replace database.sqlite with your desired database name).
• For SQLite connections, set the DB_FOREIGN_KEYS environment variable to 1 to enable foreign key constraints.

Database Connection URLs

• Database connection URLs are typically structured in the format <a>scheme://username:password@host:port/database</a>.

Configuring Read/Write Connections

• In Laravel, read and write connections can be configured separately, allowing for load balancing and master-slave configurations.
• Read and write connections can be configured in the config/database.php file.
