Scaling from single server deployments to large, complex multi-site architectures.įirst of all, we should know what is document oriented database? Example of Document-Oriented Database.The primary purpose of building MongoDB is: It may be a very genuine question that - 'what was the need of MongoDB although there were many databases in action?'Īll the modern applications require big data, fast features development, flexible deployment, and the older database systems not competent enough, so the MongoDB was needed.
