Previously MySQL used powerdesigner to design er diagrams, but now it has been changed to mongodb. Is there any useful software for drawing er diagrams?
The E-R diagram is a diagram used to describe the relationship between entities in the relationship model. The first point of MongoDB’s use is to remove relations as much as possible, and to use anti-normal form to centralize data in one document as much as possible, because the cost of relations in a distributed environment is too high, which will have a serious impact on efficiency.
Therefore, when Mongo is adopted, the first task is to eliminate the relationship, thus naturally there is no room for ER diagram.
