Your roadmap to understanding whether NoSQL is right for you.

Technology that can scale, perform and deliver continuous availability 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 Web and mobile 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 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.

Step 2


There are a number of ways to move existing data into Cassandra on a one-time or continual basis. The information below will help guide you in migrating data from RDBMS’s to Cassandra.

Step 3


Learn how to manage and optimize DataStax Enterprise clusters for maximum performance and uptime.
