DATA ANALYTICS CHALLENGE S3 SPARK

This ETL project, inspired by the Alkemy Data Analytics Challenge, was adapted to incorporate AWS S3, AWS RDS, and Spark as a way to practice working with cloud services and big data tools. The process extracts data from three sources—Datos Argentina Museos, Salas de Cine, and Bibliotecas Populares—stores it in an S3 bucket using a structured format {source}/{year-month}/{source}-{exact date}, and then loads it into a relational database for further analysis.
