MongoDB’s goal is to demonstrate to clients why a document database might be a better fit for particular business needs. But many businesses are used to thinking of MySQL as a one-size-fits-all solution. Of course, neither type of database is suitable for every problem. But it also risks slowing down under larger data loads. The write concern briefs the guarantee that MongoDB provides at the time of reporting on the success of a write operation. It does not grant privileges for the User and Role Management. An array of additional roles to grant to the user. dbAdmin Role: This role gives the ability to the user to perform administrative tasks such as schema-related tasks, indexing. That makes it more efficient to gather up a collection of relevant data than if you had to search all rows and columns of every table in a database. readWrite Role: This role provides all the privileges of the read role plus the ability to modify data on all non-system collections. In MongoDB, individual datapoints are connected by “pointers” to related datapoints. This model, proponents say, explains why MongoDB is faster than relational databases. Mongo, for instance, is a “document database” with a looser structure that allows users to store data even if it isn’t consistent or highly structured.įor example, if you had a contact list with multiple phone numbers for two people, a physical address for another, and no last name for a fourth, a document database could store the relevant data without adding empty rows and columns for what’s missing. MongoDB and other so-called “NoSQL” alternatives to relational databases, by contrast, organize data in different ways.
