Migrating to NoSQL: The Process

by Angela Guess

Matt Asay of TechRepublic recently discussed the process for migrating from a relational database to a NoSQL database. He writes, “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.”

He goes on, “NoSQL databases are new enough that many database engineers will be RDBMS experts, but NoSQL neophytes. This shouldn’t deter developers hoping to use NoSQL in a new project. After all, most NoSQL databases are open source and come with built-in communities, happy to help new users get up to speed. Part of this shift is one of nomenclature. For example, as relational database expert Chris Bird points out, the syntax in NoSQL Land differs greatly from SQL, and may require some mental gymnastics for new users.”
