In this module, we’re going to explore the history and the rationale behind NoSQL databases, their relationship to RDBMS, and dive into the basics of MongoDB. We will install MongoDB, create a database, collections and perform CRUD operations. We will end this module by integrating MongoDB with Ruby Shell and try out some simple examples.

In this module, we’re going to explore the fundamentals of the Aggregation framework in MongoDB. We will work on examples where you will process data records and return computed results. You will learn about and get to work on hands-on examples where you will be grouping values from multiple documents and performing a variety of operations on the grouped data to get a single result. We will look at a number of aggregation commands and paging. We will explore some advanced concepts like full text search, GridFS, Geospatial API, and wrap up the module with detailed demonstrations of all the capabilities presented in this module.

In this module, we’re going to explore Mongoid, which is an Object-Document-Mapper (ODM) for MongoDB written in Ruby. We will learn to integrate Mongoid with Rails and work to understand document and relationship mapping, as well. We will work on a number of queries using the Mongoid API and wrap up the module by implementing Rails/Mongoid Model View Controller.
