Looking at NoSQL these days, I still don’t quite understand the conversion from tables, rows and columns in traditional relational databases to NoSQL.
For example, the simplest blog database design has a classification table, an article table and n articles for each classification.
How does this traditional relational database design change to Mongodb and Redis?
After using Mongodb, I designed it this way. For the article:
- Release time
- Tags (using array types)
Through tag and classified query articles, aggregated Map/Reduce, etc. can be used.
For Redis, handling these is mainly implemented in their own applications.
