Introduction to Redis

Course Summary

The Introduction to Redis training course is designed to demonstrate the fundamental elements of the NoSQL database Redis. We cover basic installation, storage configurations and how to insert and retrieve data from Redis. We will also cover how to efficiently design a performant Redis key-value data store.

Learn to use the NoSQL database Redis.
Anyone interested in or has a project that will require Redis storage interaction.
