1. connection path problems:
-Loop
In relational database mode, a common join path that returns too few rows is called a loop. A loop is a group of joins. It defines closed joins of a group of tables in the pattern, for example:
Solution: Create an alias table (a copy of the base table ).
-Chasmtrap)
The fault trap is a common problem in the relational database model. The connection path returns more data th
course I mean their attributes ). As a result, the PO is independent, and the data persistence layer is independent, so it is not subject to any business interference. In this case, the business logic layer is also independent and will not be affected by the data persistence layer. The business layer only cares about the processing of the business logic. As for how to read and give it to others! However, if we do not use the data persistence layer or hibernate, Po and VO can be the same thing,
