"Bir kullanıcı, Mongoose'u kullanarak belirli bir koleksiyondaki belgeler için şema tanımlayabilir. MongoDB'deki verilerin oluşturulması ve yönetilmesinde büyük kolaylık sağlar."
Artık mongoDB yerel sürücüsüyle şema tanımlayabilirsiniz.
## Yeni koleksiyon için
`db.createCollection("recipes",
validator: { $jsonSchema: {
<<Validation Rules>>

}
)`
## Mevcut koleksiyon için
`db.runCommand( {
