Abstract: Although SQL database is a very useful tool, after 15 years of outstanding performance, the monopoly will be broken. This is only a matter of time: I was forced to use relational databases, but I finally found that I could not meet my needs. For details, see my IT-Homer blog: Comparison of eight mainstream NoSQL databases NoSQL is a brand new revolution
