Multi-file Schema

Prisma uses an implicit approach that simply merges all schema files in a folder. ZModel uses explicit `import` syntax for better clarity and flexibility.

When your schema grows large, you can break them down to smaller files and stitch them together using the import statement.

import './post'

model User {
    id    Int   @id
    posts Post[]
}

import './user'

model Post {
    id       Int    @id
    content  String
    author   User   @relation(fields: [authorId], references: [id])
    authorId Int
}

import './user'
import './post'

After type-checking, these files are merged into a single schema AST before passed to the downstream tools.
