MongoDB Fundamentals – Getting Started – Day 1 of 6

This entire week, I am going to discuss the Fundamentals of MongoDB. Today is the first post in the six post series. We are going to learn about getting started with MongoDB. I have recently build a Video Course at Foundations of Document Databases with MongoDB focusing on helping users to get started with MongoDB quickly and efficiently.

Getting Started

MongoDB is a NoSQL database and that means along with SQL concepts, it is also following NoSQL concepts. If your application needs to store and retrieve unstructured data, you should consider a NoSQL document database like MongoDB. They are incredibly fast due to their nature of the schemaless and also are very flexible in terms of storing the data. The most popular NoSQL database I have come across is MongoDB.

If you are going to get started with MongoDB, here are a few keywords you should know about it before you get started with it.

Document Database

A document database is a type of nonrelational database that is designed to store and query data as JSON-like documents. All the document databases are built around JSON like documents so they are natural and flexible for developers to work with. Document databases make it easier for developers to store and query data in a database by using the same document-model format (i.e. JSON) they use in their application code. XML databases are a subclass of document-oriented databases that are optimized to work with XML documents.

CAP Theorem

The CAP theorem applies to distributed systems that store state. The theorem states that shared-data systems can only guarantee two of the following three properties:

Consistency — A guarantee that every node in a distributed cluster returns the same, most recent, successful write.

Availability — Every non-failing node returns a response for all read and writes requests in a reasonable amount of time.

Partition Tolerant — The system continues to function and upholds its consistency guarantees in spite of network partitions.

MongoDB positions rights in the middle of C and P.

MongoDB Atlas

I have built my entire Pluralsight MongoDB course with the help of MongoDB Atlas. It is the global cloud database service for modern applications. It is very easy to get started with it and also you do not require any prior knowledge to use this project. MongoDB Atlas is available as a fully managed service for a flexible and scalable document database.

If you are beginning with the MongoDB, you can easily install the sample databases on your cluster and practical various demonstrations. I also cover this in my Pluralsight course.

MongoDB Compass

MongoDB Compass is a GUI for MongoDB. It helps us to visually explore our data. We can run ad hoc queries in seconds with the help of this tool. It is fully capable to run various  CRUD functionality and also helps us view and optimize your query performance.

Along with the command prompt, I believe everyone should have a MongoDB compass. Once you install, you can see your data by running find operation and also modify it with the update, insert, or delete operation.
