MongoDB for Developers with Python Transcripts
Chapter: Course conclusion
Lecture: Lightning review
0:01 Before we put the wraps on this course let's do a quick lightning review of each chapter that we've covered.
0:07 We're certainly not going to cover everything that we covered in the chapter,
0:10 this is just a really quick review, but maybe the main takeaway from each chapter. So we began the course by talking about what is NoSql,
0:18 and I think there's a little bit of a misunderstanding or maybe multiple definitions of what NoSql means sometimes people say it's not only sql,
0:27 sometimes you people say it means that there's no sql, the language involved in this. Well what we saw is looking at the history back in 2009,
0:35 this concept of NoSql came about by a meeting of people working on horizontal scales type of databases,
0:43 like what trade-offs do they make against relational databases, so that they are more easily horizontally scalable,
0:49 and basically cluster friendly databases. That world it's not whether or not there's no sequel
0:54 or there is sequel in the language, it's really about the style of databases and the trade-offs around how they work with that data.
