MongoDB vs RDBMS: MongoDB being the schema-less database, supports the object model. Here any field can be indexed. It can run on multiple servers.
RDBMS stands for the relational database management system. It provides a high level of security for information. It is quite quick and provides primary keys for the fast execution.
Difference between MongoDB and RDBMS
The below table explains the differences between the MongoDB and RDBMS:
|It is the relational database||It is a non –relational and NoSQL document-based database.|
|It needs tables with relations to store data.||Other than usual rows and columns, it utilizes the document storage format i.e., BSON.|
|A proper designing of the table, data structure, and relations need to be done before coding.||Coding does not need a table, and objects can be very easily modified at a lesser cost.|
|Here SQL language is used for coding.||JSON can be used other than SQL.|
|The primary key is used to distinguish the rows exceptionally.||The MongoDB database provides the default id.|
|In huge data operations, vertical scaling is done by increasing RAM, which is too costly.||Here, Sharding technique i.e., horizontal scaling is done, which means adding more servers.|
|Transactions, including multiple tables, are done by Joins.||Join is not used, but it supports embedding documents inside another one keeping the size limit up to 16mb.|
|RDBMS ensures ACID properties—Atomicity, Consistency, Isolation, and Durability during transactions||CAP theorem –Consistency, availability, and partition tolerance is maintained.|
|The execution process is slow as compared to NoSQL.||It is almost 100 times faster than RDBMS.|
