database whose core is the relational join nesting, and because it stores semi-structured data such as Xml,json, it is very convenient to provide rest services. 4. Consider: Any merit comes at a price. There is no silver bullet, and one solution can solve all problems, especially under the constraints of hardware conditions The pros and cons of relational databases are a problem worth thinking about, only to solve this problem to really know wh
