MongoDB

MongoDB is arise in the mid-2000s under NoSQL community. Dwight Merriman and Eliot Horowitz, who had encountered development and scalability issues with traditional relational database approaches while building Web applications at DoubleClick, an Internet advertising company that is now owned by Google Inc. According to Merriman, the name of the database was derived from the word humongous to represent the idea of supporting large amounts of data. Merriman and Horowitz helped form 10Gen Inc. in 2007 to commercialize MongoDB and related software. The company was renamed MongoDB Inc. in 2013. The database was released to open source in 2009 and is available under the terms of the Free Software Foundation’s GNU AGPL Version 3.0 commercial license.

MongoDB allow to use collections and documents instead of using tables and rows as in relational databases. Documents comprise key-value pairs. Collections contain sets of documents and functions just like database schema in relational databases.

Below are few characteristics of the MongoDB:

• Written in: C++
• Main point: Retains some friendly properties of SQL. (Query, index)
• License: AGPL (Drivers: Apache)
• Protocol: Custom, binary (BSON)
• Master/slave replication (auto failover with replica sets)
• Sharding built-in
• Queries are javascript expressions
• Run arbitrary javascript functions server-side
• Better update-in-place
• Uses memory mapped files for data storage
• Performance over features
• Text search integrated
• GridFS to store big data + metadata
• Has geospatial indexing
• Data center aware
