The Table Module pattern organizes business logic in classes or modules where each one represents a table in the database, and the methods of this class operate on the table's records.

# When to use it?

This pattern is especially useful in applications with a complex data model where business operations are closely related to the database table representations. In this model, each class or table manages its own responsibilities.

# Detailed Example in Java

Let's see an example of how a Table Module could be implemented to handle operations on a Students table.

public class StudentsModule {
    private Database db; // our database abstraction

    public StudentsModule(Database db) {
        this.db = db;
    }

    public void addStudent(String studentId, String name, String email) {
        // Adds a new student to the table
        db.execute("INSERT INTO students (id, name, email) VALUES (?, ?, ?)", studentId, name, email);
    }

    public void updateStudentEmail(String studentId, String newEmail) {
        // Updates the student's email address
        db.execute("UPDATE students SET email = ? WHERE id = ?", newEmail, studentId);
    }

    // Other methods related to operations on the students table
}

This module encapsulates all operations related to the Students table, providing a centralized point to manage this data.
