Instructor: Matteo Devigili

This module focuses on storing, querying, and manipulating data. In particular, it discusses PostgreSQL (a prominent, advanced, and open-source relational database) and MongoDB (a schema-free database especially useful with evolving streams of data). In the last week, a more exploratory lecture (not strictly required to complete the final coursework) goes through Apache Spark (a cluster-computing framework that can scale SQL, machine learning, and network analysis pipelines) leveraging on PySpark.
