ORM integration modules are essential components of the Spring MVC framework. ORM stands for object-relational mapping and refers to the process of mapping objects in code to data stored in a database. This is often done with frameworks such as Hibernate, JPA, or iBatis which automate many of the tedious aspects involved in creating database applications. Spring MVC has a number of integration modules that allow developers to easily integrate their own ORM implementation into their projects. These modules provide common functionality like creating sessions, generating and executing queries, and so on. They also take care of keeping all the configurations in sync with each other, making it easy for developers to use different databases without having to constantly update their code. With these helpful ORM integration modules, developers are able to quickly get started building dynamic web applications with the power of the Spring MVC framework.
