Intro to MongoDB

I finally was able to write down some of my notes from watching the Pluralsight: Intro to MongoDB course.  These are just my notes but I absolutely recommend you watch the course and signup for Pluralsight.  MSDN subscriptions typically come with some free time with Pluralsight.

Jump start your learning and good luck!

                Server
                Query/Manipulate
                Indexing

No Schema
Single Document write scope - No locking
Eventual Consistency - multiple options
                Fire and Forget
                Majority
                Eventual Consistency
Scalability
                no Schema - Really -> No schema Enforcement


Server Setup

                Mongod
                                just Create data file/ Run
                mongod --install {installs as service}
                net start MongoDB

MongoDB Shell
                Commands
                                show dbs
                                use foo
                                db -> shows connected db
                                help -> shows all commands

                Can write up your own Editor
                                - Sublime
                                - NotePad ++
                mongorc.js -> always runs

Replica Set
                Primary -> Secondary  & Arbiter (helps to determine who takes over w/ issues)

                                Insertion is ascending

                db.foo.save({})
                db.foo.insert({}) -> will throw for duplicate key if saving with specific ID

                db.foo.update( query, update, options )

If you read my ASP.NET Core WebAPI Journey - Step 1, we touched on the fact, we wanted to build our class library first as this will really do most if not all of the business logic. We’re going to create this in a .NET Standard library so we can start using this same library in both .NET Core or .NET framework class libraries in this and future guides going forward. Our business class library will start off doing three things.   ·         Log generic topics into the database ·         Log emails to be sent ·         Send emails Before the creation of the library itself, we need to model our database to store these values. This will be used for logging and our automated email queue. Below is a high-level overview of all of the steps to create this library. You can follow along but all of the code is available to download at   https://github.com/RichardWysocki/LunchandLearn . Creating our Database In this guide, we are going to use SQL Server.

You buy that fixer upper and you put all your free time into the biggest financial investment you’ve ever made. Or did you have kids!   Wow they can suck every minute of your time. I know so many of my professional friends who enjoy getting that development task or story done that they forget to learn. I might focus on how this doesn’t help you or your career in a different article but today I wanted to highlight to remember to make the time. I know you want to learn, it’s just that life becomes busy and you forget. If you just need that little extra push or reminder here are a few ideas. Personally, I’m fortunate that I use two of the best online learning platforms around. These are the Pluralsight and LinkedIn Learning platforms. Both have great technical and programming courses.   Each of these platforms have very nice remin
