Exploring the technical principles of the UJO ORM framework in the Java class library

Explore the technical principles of the UJO ORM framework in the Java class library Abstract: Ujo ORM is a framework that implements object relationship mapping (ORM) in the Java library.This article will explore the technical principles of the UJO ORM framework in the Java class library to help readers better understand and apply this framework.The article starts with the concept of clarifying UJO ORM, introduces the importance of ORM in software development, and explains the structure and design ideas of the UJO ORM framework in detail.Subsequently, the UJO ORM was demonstrated how the UJO ORM realized the mapping relationship between the class and the database, including the common operations such as object persistence, query and association.Finally, the article will explore the performance optimization of UJO ORM and the common problems and solutions in the development process, so as to help readers better use the UJO ORM framework in practical applications. I. Introduction \ t1. Introduction to Ujo ORM \ t Introduction UJO ORM framework and its role in the Java class library. \ t2.
