DWBIConcepts has provided an introductory tutorial on NoSQL databases. The tutorial begins, “NoSQL is not the name of any particular database instead it refers to a broad class of non-relational databases that differ from classical relational database management systems (RDBMS) in some significant aspects, most notably because they do not use SQL as their primary query language, instead providing access by means of Application Programming Interfaces (API).”
It continues, “NoSQL databases and data-processing frameworks are primarily utilized because of their speed, scalability and flexibility. Adoption of NoSQL in the enterprise level, however, is still emerging. Some consider it the absolute apogee of achievement, while others maintain it at the peak of the Inflated Expectations Phase of Gartner’s Hype Cycle, used to characterize the over-enthusiasm or ‘hype’ and subsequent disappointment that typically happen with the introduction of new technologies. Still others relegate it to an inferior and inconspicuous position in favor of columnar relational databases such as Sybase IQ or Oracle 11g.”
