In this article we will try to explain how to create your own resource model for getting data from the product flat tables. First of all you need to know why we should do this. It’s simple.

Understanding Magento Product Flat Tables

Magento’s Entity-Attribute-Value (EAV) structure is designed for flexible data storage, allowing for the dynamic addition of attributes to entities like products without altering database tables. However, this flexibility can lead to performance issues due to the complex queries required to retrieve data.

Product flat tables, a feature in Magento, address this by consolidating data into a single, flat structure, enhancing query efficiency and site performance. While this improves speed, especially for product listing and filtering, it can limit the dynamic nature of attribute management and increase database size, potentially impacting other areas of performance. This trade-off is important to consider when optimizing Magento stores.

For example, you have a category page with configurable products and you need to get all attribute values on this page.
