## Core Entity Relationships

### Park-Ride Relationship
```php
// Park Model
public function rides()
{
    return $this->hasMany(Ride::class);
}

// Ride Model  
public function park()
{
    return $this->belongsTo(Park::class);
}
```

### Park-Operator Relationship
```php
// Park Model
public function operator() 
{
    return $this->belongsTo(Operator::class);
}

// Operator Model
public function parks()
{
    return $this->hasMany(Park::class);
}
```

### Ride-Designer/Manufacturer Relationships
```php
// Ride Model
public function designer()
{
    return $this->belongsTo(Designer::class);
}

public function manufacturer()
{
    return $this->belongsTo(Manufacturer::class);
}
```
