Advantages
- Schemaless: MongoDB is a document-based database, in which one collection holds different documents
- It has no complex joins
- The database is easy to scale in size
- MongoDB enables horizontal scalability, by using a technique called sharding. Sharding distributes the data across physical partitions to overcome the hardware limitations
- It provides ACID properties at the document level, as in the case of relational databases
- It supports replica sets, meaning that a failover mechanism is automatically handled. If the primary server goes down, the secondary server becomes automatically the primary server, without any human intervention
- It supports the common authentication mechanisms, such as LDAP, AD and certificates. Users can connect to the database over SSL and the data can be encrypted
- MongoDB can be a cost-effective solution in regards to hardware and storage
Disadvantages
- MongoDB has no Joins
- Memory usage problems
- Currency issues
- It doesn’t have transactions
