MongoDB Tutorials

In this detailed Resource page, we feature an abundance of MongoDB Tutorials!

MongoDB is a cross-platform document-oriented database system and it is free and open source software. Classified as a NoSQL database, MongoDB eschews the traditional table-based relational database structure in favour of JSON-like documents with dynamic schemas (MongoDB calls the format BSON), making the integration of data in certain types of applications easier and faster.
 
MongoDB supports field, range query, and regular expression searches. Queries can return specific fields of documents and also include user-defined JavaScript functions. Queries can also be configured to return a random sample of results of a given size. Fields in a MongoDB document can be indexed with primary and secondary indices.
 
MongoDB provides high availability with replica sets. A replica set consists of two or more copies of the data. Each replica set member may act in the role of primary or secondary replica at any time. All writes and reads are done on the primary replica by default. Secondary replicas maintain a copy of the data of the primary using built-in replication. When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary. Secondaries can optionally serve read operations, but that data is only eventually consistent by default.
 
The below tutorials will teach you how to install MongoDB and how to use its operators, functions and techniques so that you can develop your own MongoDB based applications.
