Import Data to a Firestore Database

Why it matters

Firestore illustrates a document source with different access and consistency characteristics from a relational warehouse. Those differences shape how an agent should retrieve and update data.

What to practise

Set up Firestore, write import code, generate test records, and load them into a collection while observing the application’s responsibility for document shape and validation.

How it fits

Compare this source with BigQuery and Cloud SQL in subsection 3.2. Choose an integration contract from the domain’s access patterns, not from a generic database label.
