and disadvantages. In the "select" section, I will introduce how to select a framework.

Finally, in the "Advantages and Disadvantages" section, I will discuss all the advantages and disadvantages of a

This is the best way to keep the software away from bugs, and to reassure users that Hibernate's development is very active, and that it also has the benefit of discovering which features users really need.
Regression test
I think the entire Java community is now very focused on automated regression
