  • It affords the facility of relational databases by supporting full ACID transactions, joins in queries, and two forms of relationships as an alternative of 1: reference and embedded.
  • MongoDB additionally helps excessive availability, utilizing a replication facility referred to as duplicate set (a gaggle of MongoDB servers that preserve the information set thus offering computerized failover, information redundancy, and availability). There’s additionally help for horizontal scalability the place sharding distributes information throughout a cluster of MongoDB servers.
  • To safe a database deployment, MongoDB gives numerous security measures, equivalent to authentication and authorization, entry management, TLS/SSL encryption, auditing, and extra.
  • Additionally, it gives a safety guidelines which is a listing of really helpful safety measures that it’s good to implement to guard a MongoDB deployment. Additionally, guarantee that you’ve got hardened safety on the community and server layer.

MongoDB Shopper and Instruments

Moreover, MongoDB comes with some helpful database instructions and instruments to watch its efficiency equivalent to mongostat, mongotop, and extra, that make it easier to to view real-time statistics concerning the state of a working MongoDB occasion on the localhost.

To combine your functions or exterior programs with a MongoDB database, you should utilize one of many many official connectors and libraries.
