What is nwrug-mongodb?

This repository contains the slide deck and accompanying demo code from a talk about MongoDB given by Adam Holt at the North West Ruby User Group (NWRUG). It is essentially a presentation package rather than a standalone application, designed to teach people the basics of working with MongoDB. MongoDB is a type of database that stores information as flexible, JSON-like documents rather than in rigidly structured tables. The talk walks through how this approach works and why it can be useful for certain types of projects. The JavaScript files in this repo serve as live examples to accompany the slides, letting an audience see practical queries and database operations in action. The primary audience for this material would be developers who are new to MongoDB or curious about moving away from traditional relational databases. For example, a Ruby on Rails developer attending the user group might look at these examples to understand how to store and retrieve data without needing to define a strict database schema upfront. Because the README doesn't go into further detail, it is unclear exactly which specific MongoDB topics the talk covers or whether the demo code is still maintained. The repository appears to be an archived resource from a local tech meetup, serving as a historical reference for anyone who attended the session or wants a basic, code-driven introduction to document databases.
