In a sign of the growing enterprise interest in new technologies for big data applications, NoSQL database vendor MongoDB has raised $150 million in a fresh round of funding from several major firms including Salesforce.com, Intel Capital and Sequoia Capital. With the new funds, MongoDB has so far raised $231 million from investors since launching in 2007. The latest round is one of the largest single funding rounds for a database company and makes MongoDB one of the best-funded big data startups in the market. MongoDB used to be known as 10Gen but changed its name last month.
