Directus supports various databases, though each vendor has their own simple data types. To standardize these differences, Directus has a single set of types that are mapped to the vendor-specific ones.

| Group | Types |
| ------------- | -------------------------------------------- |
| Text | `String`, `Text`, `UUID`, `Hash`, `Alias` |
| Numeric | `Integer`, `Big Integer`, `Float`, `Decimal` |
| Boolean | `Boolean` |
| Date and Time | `Timestamp`, `DateTime`, `Date`, `Time` |
| Binary | `Binary` |
| Structured | `JSON`, `CSV` |

Fields that do not map directly to an actual database column are called "alias" fields, and include presentational fields and certain relational fields.

Geospatial fields are used to store data in [GeoJSON](https://geojson.org/) format. These types are only supported if your database supports spatial extensions.

## Creating Fields

When creating a new field, you must first select an [interface](/data-modeling/interfaces) and provide some basic configuration. Basic configuration will depend on the interface selected, but all fields have some common characteristics.
