The Active Record pattern is a fundamental concept in ORM (Object-Relational Mapping), and Cuba embraces it to provide a seamless and intuitive way to interact with your data. Think of Active Record as a dynamic proxy that sits between your code and the database, translating your object-oriented code into appropriate database operations.

Imagine you’re working with a Customer object in your code. Using the Active Record pattern, you can simply call customer.save() to persist it to the database, or customer.delete() to remove it. No need to write complex SQL queries or worry about mapping between your object properties and database columns.

This pattern simplifies data manipulation drastically, as you can now interact with your data using the familiar syntax of an object. You can create, retrieve, update, and delete objects without having to deal with the underlying database details.

Example:

// Create a new customer
Customer customer = new Customer();
customer.setName("John Doe");
customer.setEmail("[email protected]");

// Save the customer to the database
customer.save();

// Retrieve a customer by ID
Customer retrievedCustomer = Customer.find(1);

// Update the customer's name
retrievedCustomer.setName("Jane Doe");

// Save the changes
retrievedCustomer.save();

// Delete the customer
retrievedCustomer.delete();

As you can see, the code is concise, easy to read, and maintains a clear separation of concerns. The Active Record pattern enables you to focus on your business logic while Cuba handles the underlying data operations.
