-UML class diagrams are often used to describe the static structure between classes when describing the design mode. The purpose of this article is to allow the readers to understand the UML class diagrams and to figure out several relationships in the UML class diagrams. -In the subsequent design model learning process, only these two points are adequate. More advanced is beyond the scope of this article. Johnconnor design pattern note series directory Johnconnor design patterns Note (I) Wha

1.2 Different types of replicationNow that you have completely understood the limitations of physics and theory, you can start learning different types of replication.1.2.1 Synchronous and asynchronous replicationThe first distinction we can make is the difference between synchronous replication and asynchronous replication.What does that mean?
