Laravel Database: What it is and what it is for

Laravel is a framework that offers many facilities when it comes to connecting to databases. It has several advanced features to help deal with the most diverse database systems, combining this with easy access to the information necessary for our applications. This framework does this through its Query Builder (query builder) and through ORM (object-relational mapping) tools Eloquent.

Query Builder

Laravel's Query Builder offers a simple way to create and run queries against databases. They can work well with all databases supported by Laravel ( and listed below in the article).

In addition, Query Builder is also safe, as it uses PDO (PHP Data Objects), which is now the recommended standard for secure and effective connection with databases using PHP, through parameters to protect against SQL Injection.

The Query Builder is also highly flexible, allowing you to interact with the database without having to change large chunks of code when needing to switch from one database to another (as long as the databases in question are supported by Laravel, obviously).

Eloquent ORM

Eloquent is an object-relational mapping tool used by Laravel for interaction between databases and object-oriented applications in a more abstract and flexible way, making the differences between the data model object-oriented approach used by applications and the relational model used by RDBMS (Relational Database Management Systems) become "transparent" to developers and without having to write a line of code SQL directly in the application. Eloquent does this through the use of a Model class (from the MVC concept) for each database table. It is through this Model that we are able to perform operations with the database using class methods, such as the famous CRUD operations (create, read, update and delete data)

Currently in its new version (11.x) Laravel supports the following databases:

• MariaDB version 10.3 or higher
• MySQL version 5.7 or higher
• PostgreSQL version 10.0 or higher
• SQLite version 3.26.0 or higher
• SQL Server version 2017 or higher

Laravel stands out as a complete and flexible solution for database management, offering a range of features that simplify developers' lives and increase application efficiency. With powerful tools such as Query Builder and Eloquent ORM, the framework offers everything needed to develop robust and scalable applications, while ensuring security and performance. Whichever database you choose, Laravel is prepared to deliver a fast and reliable development experience.
