DBML - Database Markup Language

DBML (database markup language) is a simple, readable DSL language designed to define database structures.

For more information, please check out DBML homepage

Benefits

• It is simple, flexible and highly human-readable
• It is database agnostic, focusing on the essential database structure definition without worrying about the detailed syntaxes of each database
• Comes with a free, simple database visualiser at dbdiagram.io
• Also comes with a free database documentation app at dbdocs.io

Example

Example of a database definition of a simple blogging site:

Table users {
    id integer
    username varchar
    role varchar
    created_at timestamp
}

Table posts {
    id integer [primary key]
    title varchar
    body text [note: 'Content of the post']
    user_id integer
    created_at timestamp
}

Ref: posts.user_id > users.id // many-to-one
