# What is Column?

Column is a decorator that adds a column to the database table. You can define a column by adding the <mark style="color:purple;">**`@Column`**</mark> decorator to a class property within a schema.

```typescript
/* ./schemas/photo.ts */
import { Schema, Column, Unique, Default } from 'nexorm/decorators';

@Schema
class PhotoSchema {

@Column
@Unique
static photoId = String;

@Column
static photo = Buffer;

@Column
@Default(new Date())
static date = Date;

};
```
