Database Architecture and NoSQL at Scale with Deno
About this course
In this final course of the PostgreSQL for Everybody specialization, you’ll explore how modern databases are built and scaled. You’ll begin by examining PostgreSQL’s architecture, including how it implements CRUD operations, indexing, transactions, and ACID (Atomicity, Consistency, Isolation, Durability) guarantees. Then you’ll shift to NoSQL systems using the Deno environment. You’ll learn how Deno implements a distributed Key-Value store and how it applies BASE (Basic Availability, Soft State, Eventual Consistency) principles. Through hands-on projects, you’ll deploy your own Deno KV service on Deno’s global infrastructure and build a Deno client to interact with it. By the end, you’ll understand the design tradeoffs between ACID and BASE databases and gain practical experience deploying and scaling both relational and NoSQL systems.
