• a ModelResource usage example: https://github.com/magento/magento2/tree/1d97cd9ddee038c9b93c43b74c8e318702a70a33/lib/internal/Magento/Framework/Model/ModelResource/
• a ResourceModel usage example: https://github.com/magento/magento2/tree/1d97cd9ddee038c9b93c43b74c8e318702a70a33/app/code/Magento/Catalog/Model/ResourceModel/
