SQL Mapping Explained: ORM Basics

In SQL, using mapping typically refers to mapping tables and data from a database to an object model, enabling Object-Relational Mapping (ORM). In the Java language, popular ORM frameworks like Hibernate and MyBatis provide convenient APIs and tools to help developers achieve mapping relationships between the database and object model.

When using an ORM framework, developers typically need to define entity classes to map table structures in the database, and specify the mapping relationship between object properties and database fields through configuration files or annotations. The ORM framework will automatically generate SQL statements based on these configurations, simplifying the writing and management of database operations.

In general, utilizing SQL mapping involves defining entity classes, configuring mapping relationships, and performing database operations using APIs provided by ORM frameworks. By using ORM frameworks, developers can easily manipulate databases, enhance development efficiency, and reduce code volume.
