n8n + Firebase: NoSQL, Realtime Database, and Cloud Functions for Dynamic Apps

After reviewing Supabase and its PostgreSQL-based architecture, let’s turn to another powerful BaaS platform — Firebase by Google. Firebase takes a completely different approach: NoSQL, real-time data sync, and deep integration with the Google Cloud ecosystem.

If your app needs real-time updates, schema flexibility, and strong mobile support, the Firebase + n8n combo might become your key automation tool.

038 | Databases in Detail: MongoDB — A Flexible Document-Oriented Database

June 30, 2025

We’re wrapping up our database series with MongoDB — one of the most popular document-oriented NoSQL databases. Unlike relational systems like MySQL and PostgreSQL, MongoDB offers high flexibility, scalability, and performance for working with semi-structured and unstructured data.

What is MongoDB?

MongoDB is a free and open-source (SSPL/Apache 2.0) document-oriented NoSQL database that stores data in a JSON-like format called BSON (Binary JSON). Unlike relational databases that use fixed schemas, MongoDB stores “documents” (analogous to records) with a dynamic schema. This means documents in the same “collection” (similar to a table) can have different sets of fields — giving developers incredible flexibility.

037 | Databases in Detail: Redis — A High-Speed Key-Value Store and Cache

June 29, 2025

We’ve already explored relational databases (MySQL, PostgreSQL, SQLite), which are great for structured data and complex queries. Now we move into the world of NoSQL, starting with one of its brightest stars — Redis (Remote Dictionary Server). Redis is an incredibly fast and versatile server often described as a “data structure server on steroids.”

What is Redis?

Redis is a free and open-source (BSD licensed) NoSQL key-value database that stores data in memory (in-memory). Unlike traditional disk-based databases, Redis is designed to deliver maximum data access speed. While it’s a key-value store, Redis stands out because the values can be not only strings but also rich data structures like strings, lists, sets, hashes, sorted sets with scores, bitmaps, and hyperloglogs.

033 | Database Servers: Your Digital Archive and Application Brain — Overview of Types and Use Cases

June 25, 2025

In today’s digital world, where every click, purchase, or message generates data, there’s a pressing need for efficient storage, management, and fast access. That’s exactly what database servers are for. They are the invisible but essential foundation of any dynamic application — from simple blogs and e-commerce platforms to complex enterprise systems, financial tools, and AI solutions.

What is a Database (DB) and Why Do You Need One?

A database (DB) is an organized collection of information, structured in a way that makes it easy to access, manage, and update. A database server is a software system that provides access and management services for one or more databases.
