Database is a physical container for collections. Each database gets its own set of files on the file system. A single MongoDB server typically has multiple databases.


Collection is a group of MongoDB documents. It is the equivalent of an RDBMS table. A collection exists within a single database. Collections do not enforce a schema. Documents within a collection can have different fields. Typically, all documents in a collection are of similar or related purpose.


A document is a set of key-value pairs. Documents have dynamic schema. Dynamic schema means that documents in the same collection do not need to have the same set of fields or structure, and common fields in a collection’s documents may hold different types of data.

MongoDB Overview

Difference between MongoDB and RDMS

RDBMS is completely structured way of storing data. While the NoSQL is unstructured way of storing the data. And another main difference is that the amount of data stored mainly depends on the Physical memory of the system. While in the NoSQL you don’t have any such limits as you can scale the system horizontally.

“Extremely large datasets are often event based transactions that occur in chronological order. Examples are weblogs, shopping transactions, manufacturing data from assembly line devices, scientific data collections, etc. These types of data accumulate in large numbers every second and can take a RDBMS with all of its overhead to its knees. But for OLTP processing, nothing beats the combination of data quality and performance of a well designed RDBMS.”

NoSQL is a very broad term and typically is referred to as meaning “Not Only SQL.” The term is dropping out of favor in the non-RDBMS community. You’ll find that NoSQL database have few common characteristics. They can be roughly divided into a few categories:

key/value stores

Bigtable inspired databases (based on the Google Bigtable paper)
Dynamo inspired databases
distributed databases
document databases
This is a huge question, but it’s fairly well answered in this Survey of Distributed Databases.

MongoDB Storage Model

Written in C++, MongoDB uses a memory map file that directly map an on-disk data file to in-memory byte array where data access logic is implemented using pointer arithmetic. Each document collection is stored in one namespace file (which contains metadata information) as well as multiple extent data files (with an exponentially/doubling increasing size).

The data structure uses doubly-linked-list extensively. Each collection of data is organized in a linked list of extents each of which represents a contiguous disk space. Each extent points to a head/tail of another linked list of docs. Each doc contains a linked list to other documents as well as the actual data encoded in BSON format.

Data modification happens in place. In case the modification increases the size of record beyond its originally allocated space, the whole record will be moved to a bigger region with some extra padding bytes. The padding bytes is used as an growth buffer so that future expansion doesn’t necessary require moving the data again. The amount of padding is dynamically adjusted per collection based on its modification statistics. On the other hand, the space occupied by the original doc will be free up. This is kept tracked by a list of free list of different size.

As we can imagine holes will be created over time as objects are created, deleted or modified, this fragmentation will hurt performance as less data is being read/write per disk I/O. Therefore, we need to run the “compact” command periodically, which copy the data to a contiguous space. This “compact” operation however is an exclusive operation and has to be done offline. Typically this is done in a replica setting by rotating each member offline one at a time to perform the compaction.

Index are implemented as BTree. Each BTree node contains a number of keys (within this node), as well as pointers to left children BTree nodes of each key.
