Are NoSQL Databases Better Than SQL Databases?

Показать описание

System Design is a very hot topic in intermediate to senior Software Developer roles.
In this video, we navigate what NoSQL database models mean, how they differ from Relation Databases, their history and what it takes briefly to discuss their tradeoffs. The DDIA Book is a great recommendation for System Design and I would like to summarise the chapters and my learnings here.

Thanks for the video, however,
Document-based databases may also provide join support
to some extent with sharding of schema into multiple independent schemas like separating person and education profile in a resume and finally linking them with
`.populate(document1 ', 'key1 key2 ...')`
to fetch out only those keys from the document of document1.
Ya both the databases are evolving with time and I think the future is hybrid!
