It’s been a big week for NoSQL. MongoDB, the company behind the hugely popular document-oriented database of the same name, raised $150 million from Intel Capital, Salesforce.com and other bigname investors.

The round not only brings the company’s total funding to $231 million, the most any Big Data vendor has raised to date, but also makes it the highest valued startup in New York. MongoDB CEO Max Schireson said that his company will use the capital to scale its global presence, make partners in new industries, and hire 300 new workers over the course of the next 12 months.

MongoDB announced its latest funding round on the heels of Splunk Cloud, a new AWS-based machine data analytics service. Unveiled at Splunk Conference 2013, the offering is a subscription-based edition of the firm’s flagship Enterprise platform. It integrates with on-premise deployments to help organizations make the most out of their disparate data sources.

While Splunk is bringing analytics to the cloud, Syncsort is helping enterprises unlock their legacy silos. In the latest push toward data interoperability, the vendor acquired the UK’s Circle Computer Group, a provider of application migration solutions. Terms of the deal were not disclosed.

Circle is best known for DL/2, a tool engine that lets users move workloads from legacy IBM databases to DB2 on z/OS without having to invest in costly code rewrites. Syncsort said that it will leverage the company’s technology to make its ETL lineup more attractive for mainframe users.

A few days after the acquisition, ScaleOut Software launched the latest version of its in-memory data grid platform. The new hServer V2 utilizes select Hadoop components to greatly reduce deployment times while accommodating most Java-based MapReduce applications.
