Letting data be always consistent in general can be a challenge, especially for those environments undergoing many undertakings

Senior Engineer

The document-based architecture enables me to store data in a manner that closely resembles the entities and connections seen in the real world, making it highly intuitive and simple to use.

Additionally, data retrieval and analysis are now a snap because to the robust query language, numerous indexing options, and aggregation architecture.

The API to work with it is insanely useful, allowing us to make software that connects and saves within the MongoDB environment.

With MongoDB, I have the flexibility to scale horizontally with sharding or vertically with replica sets to match my changing demands.

I have been able to handle a variety of rapidly changing data requirements with ease thanks to its flexibility and scalability.

Software developer

Mongo DB in some instances utilises no SQL, allowing for more junior developers to easily learn and understand databases as well as Mongo’s multiple platform language extensions.

I studied about NoSQL databases few years ago and this was the first database that I used to integrate with an application.

Best part that i like in mongodb was It's speed and large number of build in functions.

Not a suitable database for applications with complex transactions. Despite being widely used today, it is still a young technology.

I like the document-based paradigm since it fits my data's dynamic nature nicely.

Software Engineer

Mongo db supports indexing and aggregation capabilities.

It is flexible and helps to store data in document format.
