Starting with MongoDB

This document provides an overview and introduction to MongoDB, including: - MongoDB is a non-relational, document-oriented database with dynamic schemas and stores data in JSON-like documents rather than tables. - It is well suited for prototyping, quick development refactoring, non-relational data, log data and metadata. Related data and needing joins may not be the best use case. - Installation and configuration process varies by operating system but involves downloading packages and creating a data directory with correct permissions. - The MongoDB command line interface provides commands to view and manage databases, collections, documents and perform basic operations like create, read, update and delete.
Starting with MongoDB
- 1. {title : Starting with MongoDB} by César Cruz
- 2. About Me • In search of my Zen programming language • Computer Engineering Student • President ACM-ECE 2012 - 2013 • Founder hackPR @ UPRM • Opinionated • @sezalcru
- 3. NoSQL - Non-relational database - Documents, Key- Value pairs, Graphs and Objects - Dynamic Schemas - Store object in favor of tables - Quick setup and integration
- 4. So, MongoDB - Document oriented, NoSQL - Document structure is similar to JSON object - Dynamic Schema - Forgiving - JavaScript query language
- 5. Documents Image courtesy of @mongoDB
- 6. Go for MongoDB when… - Developing a quick prototype - Quick refactoring in development - Non-relational data - Log data - Metadata
- 7. Re-think MongoDB if… - Related data*** - Joins - Redundancy will be an issue - Performance can be an issue ***This is a biggie
- 8. Docs and Drivers - Open Source Project - Great documentation and community support - Docs at: docs.mongodb.org - Support for almost all major languages
- 9. Installation
- 10. OSX Using homebrew: brew install mongodb Or Download package from mongoDB website
- 11. Windows Download installation package from website
- 12. Linux Head to mongoDB website, in downloads section, select appropriate distribution. Download package distribution Or sudo apt-get install -y mongodb-org
- 13. Configuration MongoDB by default stores data in the /data/db parent directory. Create this directory using mkdir -p /data/db MongoDB must have read and write access to this directory
- 14. Start
- 15. Command Line Interface MongoDB comes with a built in Command Line Interface (CLI). To start the CLI type mongo into the console. The CLI will be your best friend for debugging.
- 16. Basic Commands - Show current database: db - Show available databases: show dbs - Switch to database: use databaseName - Show collections: show collections - Basic JS Syntax
- 17. Ok, let’s assume a Collection of Articles
- 18. To define an Article, we would need, at least: Title Contents Author Date Created
- 19. An Article document would look like this:
- 21. Create
- 22. Read
- 23. Update
- 24. Delete
- 25. Debugging A few useful commands when debugging in mongo are: db.stats() db.serverStatus()
- 26. Questions?
- 27. Demo time
