Databases in Distributed Systems

Overview

This lesson provides an overview of the challenges associated with storing data using simple file storage and highlights the advantages of using databases as a more efficient and scalable solution. It explores the two primary categories of databases, relational and non-relational, discussing their characteristics and intended use cases. The lesson also delves into the importance of data replication and partitioning techniques in achieving high availability, scalability, and performance.

Let's start with simple file storage in the following section.
