In this conceptual course (no coding required), you’ll be introduced tolearn the four major NoSQL databases, including Key-Value, Document, Column-Family, and Graph. You’ll learn about four popular NoSQL engines—including Redis, MongoDB, Apache Cassandra, and Neo4j—and when to apply them to achieve a specific business requirement. You’ll follow the data escapades of a fictional social network and learn how NoSQL can help them handle and extract insights from unstructured data like social posts.
