A NoSQL (originally referring to "non SQL" or "non relational")[1] database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases. Such databases have existed since the late 1960s, but the name "NoSQL" was only coined in the early 21st century,[2] triggered by the needs of Web 2.0 companies.[3][4] NoSQL databases are increasingly used in big data and real-time web applications.[5] NoSQL systems are also sometimes called "Not only SQL" to emphasize that they may support SQL-like query languages, or sit alongside SQL databases in polyglot persistent architectures.[6][7] Motivations for this approach include: simplicity of design, simpler "horizontal" scaling to clusters of machines (which is a problem for relational databases),[2] finer control over availability and limiting the object-relational impedance mismatch.[8] The data structures used by NoSQL databases (e.g. key-value, wide column, graph, or document) are different from those used by default in relational databases, making some operations faster in NoSQL. The particular suitability of a given NoSQL database depends on the problem it must solve. Sometimes the data structures used by NoSQL databases are also viewed as "more flexible" than relational database tables.[9]

Frida Mom, a brand dedicated to postpartum preparedness for new mothers, revealed on social media Friday that ABC and the Academy banned their advertisement from airing during Sunday's ceremony.

The pace was faster and the attacks were harsher than in the previous debates, perhaps because the stakes have gotten higher as states begin to vote. Not all seven candidates are likely to make it to the debate stage next time. For liberal activist Tom Steyer and entrepreneur Andrew Yang, in particular, it might have been their last chance.
