mongoDB

The best features of key/values stores, document databases and RDBMSes in one.

MongoDB is a high-performance, open source, schema-free document-oriented database. MongoDB is written in C++ and offers the following features:

  • Collection oriented storage – easy storage of object-style data
  • Dynamic queries
  • Full index support, including on inner objects
  • Query profiling
  • Replication and fail-over support
  • Efficient storage of binary data including large objects (e.g. videos)
  • Auto-sharding for cloud-level scalability (currently in early alpha)
  • Commercial Support Available

A key goal of MongoDB is to bridge the gap between key/value stores (which are fast and highly scalable) and traditional RDBMS systems (which are deep in functionality).

MongoDB是一个高性能的面向文件的开源数据存储项目。十分容易部署,管理和使用。可以通过网络访问,并且由C++语言编写。主要包含的功能特性有易存储对象类型的数据,完全索引支持,查询支持,复制和故障恢复支持,高效的二进制数据存储,自动处理碎片提高云层次上的扩展性。高性能,可扩展,适当的功能使这个项目的主要设计目标。

BerkeleyDb之后,可以找到的替代品之一。
