Relational Database to NoSQL

Your roadmap to understanding whether NoSQL is right for you.

Technology that can scale, perform and deliver 100% uptime is the difference between today’s successful online applications and those that fail. Relational databases (RDBMS) have struggled to keep up with the wave of modernization, leading to the rise of NoSQL as the most viable database option for online applications.

The path to understanding whether a NoSQL technology like DataStax Enterprise is right for your business as either a complementary technology to an RDBMS or as a complete replacement is a three step approach:

Step 1: Learn

Learn the difference between relational systems and Cassandra and the types of use cases it can solve. This content is applicable to both database developers, database administrators, and architects.
