Trying out mongoDB

Today I'm trying out mongoDB. MongoDB is an open source NoSQL document database.

Important resources:

http://www.mongodb.org - for any user to get to know it, and download
http://www.mongodb.org/downloads - download, manual (in html and pdf) is at the end of this page

Introduction to MongoDB for Java, PHP and Python Developers (May, 2012)

MongoDB partly obtain its performance from using memory mapped file. It supports easy replica for high up time. It keeps most important contents in memory and horizontally scale, shard automatically. It uses dynamic schema, and supports many programming languages and platforms. Its customers often have a cluster with over 100 nodes, some over 1000 nodes; data size ranges from TB to PB.

MongoDB installation package is self-contained and quite clean, in that it's a "green" software. The console is like MySQL or Python console in commands, and uses JavaScript as the query language. The comparable to MSSQL is: database - database, table - collection, row - document, column - field, index - index, table joins - embedded documents and linking, aggregate function - aggregation pipeline.

Installation on windows is recommended on Windows Server 2008 or above. Windows XP is not supported in MongoDB version 2.2 or above. Install as a windows service is easy. MongoVUE is a windows client, similar to PhpMyAdmin (actually, a web client instead of windows client) for MySql.
