Description: Arel is an SQL AST (Abstract Syntax Tree) manager designed specifically for the Ruby programming language. Its main goal is to simplify the generation of SQL queries, allowing developers to build queries more intuitively and efficiently. Arel acts as an intermediary between Ruby code and the database, facilitating the creation of complex queries without the need to write SQL manually. This not only reduces the possibility of errors but also improves code readability. Arel integrates seamlessly with ActiveRecord, an ORM (Object-Relational Mapping) framework commonly used in Ruby on Rails, allowing developers to leverage its advanced features when working with databases. Among its most notable features are the ability to build dynamic queries, manipulate relationships between tables, and generate subqueries. Arel has been fundamental in the evolution of how Ruby developers interact with databases, providing a powerful tool that optimizes the SQL query creation process and enhances productivity in web application development.
