Is MongoDB is BASE database? many articles wrote that MongoDB is acid database at document level but they not mentioned anything about that it base database or not, so I need to know about that if MongoDB is base database and support your answer with references.

CodePudding user response：

MongoDB as typical noSQL database is generally identified as BASE database , since from its earlier versions allow eventual consistency and it is ACID compliant only per single document , but since version 4.0 it support multidocument ACID transactions at replicaSet level , and since version 4.2 it support multidocumet ACID transactions at sharding cluster level.So developers can choose based on application and project requirements how to configure and use the database.
