Jusqu'à présent, nous avons surtout utilisé l'interface utilisateur web BigQuery (UI) et l'outil de ligne de commande bq pour interagir avec BigQuery. Dans ce chapitre, nous examinons les moyens d'interagir de manière programmatique avec le service. Cela peut être utile pour créer des scripts ou automatiser des tâches qui impliquent BigQuery. L'accès programmatique à BigQuery est également essentiel lors du développement d'applications, de tableaux de bord, de graphiques scientifiques et de modèles d'apprentissage automatique pour lesquels BigQuery n'est qu'un des outils utilisés.
Nous commençons par examiner les bibliothèques clientes BigQuery qui te permettent d'interroger et de manipuler par programme les tables et les ressources BigQuery.

Ces personnalisations, que nous abordons dans la seconde moitié de ce chapitre, sont plus faciles à utiliser, gèrent les conditions d'erreur de manière appropriée et éliminent une grande partie du code passe-partout.
