### Define GraphQL Schema with Directives

Source: https://graphitron.sikt.no/docs/quick_start_guide

Use @table and @field directives to map GraphQL types to your database model.

```graphql
type Query {  
    customers: [Customer]  
}  
  
type Customer @table {  
    id: ID  
    firstName: String! @field(name: "FIRST_NAME")  
    lastName: String! @field(name: "LAST_NAME")  
    email: String  
    address: Address!  
}  
  
type Address @table {  
    id: ID  
    addressLine1: String! @field(name: "ADDRESS_")  
    addressLine2: String @field(name: "ADDRESS2")  
    zip: String @field(name: "POSTAL_CODE")  
    phone: String!  
}  
```
