Can you explain DBT using layman terms with an example involving mango?

Imagine you have a basket of raw mangoes that you want to sell in a market. First, you wash them, then you slice them, and finally you pack them into boxes. Each of these steps is a transformation. DBT is like a kitchen that automates these steps. In DBT, the raw mangoes are your raw data stored in a warehouse. The SQL scripts are the recipes that tell DBT how to wash, slice, and pack the mangoes. DBT runs the recipes in the right order, only re‑doing a step if the raw mangoes change. It also checks that the final boxes are correctly filled (data quality tests) and keeps a record of how the mangoes went from raw to boxed (documentation). This way, you always have a clean, ready‑to‑sell product without manually doing each step every time.
