relationships using a single record.
The documents are grouped into collections. Each
collection is kind of a table. Each and every database

When the amount of data grows there is a need in
scaling up (getting a stronger hardware) our data store

The MongoDB database allows us to split up the data
across multiple servers. MongoDB handles most of this
Unlike many other databases that use heavy protocols

The default configuration fits the common scenario. The
learning curve is very simple.
In most cases the developer can handle the
administration tasks on his own.
MongoDB is available for the following operating
systems: Windows, MacOS, Linux and Solaris.
Drivers for writing code that interacts with MongoDB are
available for nearly every programming language,
