It's hard to keep track of all the database-related terms you hear these days. What constitutes "big data"? What is NoSQL, and why are your developers so interested in it? And now "NewSQL"? Where do in-memory databases fit into all of this? In this series, we'll untangle the mess of terms and tell you what you need to know.Continue

Today a new potential standard for document databases (and possibly other NoSQL databases) was announced: UnQL.
Dhruba Borthakur, a Hadoop Engineer at Facebook, has published part of a paper he co-authored with several of his engineering co-workers on Apache Hadoop. The first part of the paper explains Facebook's requirements and non-requirements for a data store for its revamped Facebook Messages application and the reasons it chose Apache Hadoop to power it. The paper will be published at SIGMOD 2011.Continue

Earlier today we told you about how the Hadoop business is heating up. Hadoop isn't a database, but Hbase and its alternatives are a core part of the platform. IBM is offering Hadoop products, and EMC is making an announcement next month. Microsoft has its own alternative, Azure Table Storage.Continue

Facebook will follow up on its Open Compute intiiatiive with a new initiative to improve its data storage.
According to Fast Company, the emphasis on storage is needed due to the continued sheer volume of data that Facebook's users are producing. Those hundreds of millions of users take a lot of pictures. They use Facebook to post their video. Continue
