# Data model
> Reference the core tables and schemas that power Midaz, designed for developers and database administrators working close to the data.
**This page is intended for developers and database administrators.** It contains detailed database schemas and table structures. If you're looking for a business-level overview of Midaz's entities and how they relate to each other, see [About Midaz](/en/midaz/about-midaz).
Explore the core tables and schemas that power Midaz. This reference helps developers and database administrators understand how data is structured and connected across the system. As Midaz evolves, new fields and tables may be added.
## Tables
