The industry is on the cusp of tectonic changes in how and where data are stored and processed. For over 30 years, the venerable relational database management system (RDBMS), running in corporate data centers, has held the bulk of the world’s data. This cannot continue. RDBMS technology can no longer keep pace with the velocity, volume, and variety of data being created and consumed. For this new world of Big Data, NoSQL databases are required.

Migrating to these open-source cloud databases, however, requires some preparation for enterprise IT that grew up with RDBMS.

How Big Data is changing everything

There’s nothing wrong with the traditional RDBMS. It simply doesn’t fit the world we live in anymore. Mobile, social, cloud: these and other trends complicate the variety of data and dramatically increase the volume of data being stored in the enterprise.

As RedMonk analyst James Governor argues:

The database market is back in play after a 30-year old freeze in which Oracle dominated the high end, and Microsoft the midmarket. Then along came open source, the cloud, NoSQL, in memory and everything changed….The idea that everything is relational? Those days are gone.
