8 History The term NoSQL was first used in 1998 for a relational database that omitted the use of SQL (see [Str10]). A blogger, often referred to as having made the term popular is Rackspace employee Eric Evans who later described the ambition of the NoSQL movement as “the whole point of seeking alternatives is that you need to solve a problem that relational databases are a bad fit for” (cf. [Eva09b])

9 Key Events on NoSQL Timeline Taken from Dan McCreary (2013)

10 Motives of nosql practitioners “NoSQLers came to share how they had overthrown the tyranny of slow, expensive relational databases in favor of more efficient and cheaper ways of managing data.” [Computer world report] Avoidance of Unneeded Complexity High Throughput Horizontal Scalability and Running on Commodity Hardware

11 So, what is noSQL mean actually ? NoSQL the big tent –a label for a "meme" that now encompasses a large body of innovative ideas on data management (Dan McCreary, 2013)

12 Pressure on RDBMS Taken from Dan McCreary (2013)

13 An evolving tree of data types Taken from Dan McCreary (2013)

14 Three eras of enterprise data NoSQL will not replace ERP or BI/DW systems– but they will complement them and also facilitate the integration of unstructured document data (Dan McCreary, 2013)

15 ACID vs Base NoSQL data stores give up ACID constraints in order to achieve scalability and higher performance. In fact, updates are eventually propagated and there are limited guarantees on the consistency of reads. BASE acronym, in contrast to the ACID acronym, refers to this idea: an application works basically all the time (basically available), does not have to be consistent all the time (soft-state) but will be in some known-state state eventually (eventual consistency). The BASE approach according to Brewer forfeits the ACID properties of consistency and isolation in favor of “availability, graceful degradation, and performance”. For instance, in case of Twitter, it is fine that the tweets of a person are distributed to the followers eventually in order to provide high availability and scalability.
