: Using tools like SQLAlchemy or psycopg2 , Python can execute queries directly against SQL databases, pulling results into structured formats like DataFrames.
: For datasets that exceed local memory, libraries such as PySpark or interfaces for AWS S3 and Google Cloud Storage enable the importation of massive datasets across distributed systems. ImportaciГіn de datos en Python.rar
