FORMAT: Instructor Led Training with Hands-on (60/40)

Environment: Version 2.6 on Virtualized Windows 7 (64 bit)

SUMMARY: The course begins by addressing the distinguishing features of MongoDB and a little history of it’s & NoSQL existence.

The course then divulges into the topics including MongoDB’s data modelling, indexing, aggregation, and replication & sharing. Real-time examples are used throughout the course to enable better understanding.

Take Away:

• Understanding the concept of NoSQL and its solution types 

• Basic Concepts of MongoDB 

• CRUD Operations in MongoDB 

• How to model database relationships? 

• How to create indices? What are the various types of indices and their features? 

• What is the aggregation framework? 

• What are pipeline operators? 

• Replication in MongoDB 

• What is sharding? How it is implemented? 

• Query Routing and Shard Key types
