XML Databases are not new. People have been working with the concept (if not the name) for a decade. One of the primary vendors in the space, MarkLogic, just announcedthey raised $12.5 m USD in series D funding. This is a notable event – not so much for the company but more for the technology. It shows that one of the most important communities – the VC market – believes XML databases have growth potential worth investing in in this very uncertain economy.
This ought to be enough to get you interested in exploring the technology if you haven’t already but there is more. I recently spent some time getting up close and personal with EMC Documentum’s xDB. (formerly known as xHive). I have to say I have seldom enjoyed getting my geek on more. It is an extremely powerful technology that you need to get familiar with because it will play an increasingly important role for content management technology in EMC and beyond.
