MongoDB Training in Marathahalli

MongoDB is a scalable, flexible document based No-SQL database used for ad-hoc querying, indexing and real time aggregation. It is a free, open source database that provides powerful ways to analyse and access the data. It is easy to use due to its built-in characteristics such as high availability, horizontal scalability and geographic distribution. By providing effective solutions to the users’ complex requirements, it has become popular recently.

In MongoDB, the documents can also be called as objects, because the database documents are similar to the JSON (JavaScript Object Notation) objects. The need of expensive joins can be easily reduced here by using in-built documents and arrays. It supports fluent polymorphism as it has dynamic relational schema. Third parties can build MongoDB storage engines by using pluggable storage engine API. MongoDB can be commonly coupled with Cloud or Big Data – Hadoop, AngularJS and NodeJS. Dynamic Schemas, Replication, Auto Sharding and Integrated Caching, Re-configuration and Scalability are some of the few key characteristics of MongoDB.
