![]() Used when the mapping exceeds 25 different database products at a time. This is best suited for medium-sized applications with some complex transactions. ![]() And the associations between objects are supported by the persistence mechanism, and queries are specified using an object-oriented expression language. The application is designed around an object model. 7) What is a meant by medium object mapping? This approach is successful for applications with a less number of entities, or applications with common, metadata-driven data models. The code is hidden from the business logic using specific design patterns. The entities are represented as classes that are mapped manually to the relational tables. ![]() 6) What is a meant by light object mapping? The entire application, including the user interface, is designed around the relational model and SQL-based relational operations. There are four levels defined for ORM quality. It should have a technique for ORM implementation to interact with transactional objects to perform dirty checking, lazy association fetching, and other optimization functionsĤ) What are the different levels of ORM quality?.An ability for specifying mapping metadata.Should have a language or an API for specifying queries that refer to the classes and the properties of classes.It should have an API for performing basic CRUD (Create, Read, Update, Delete) operations on objects of persistent classes.It works by transforming the data from one representation to another.ģ) What does an ORM solution comprises of? It is the programmed and translucent perseverance of objects in a Java application in to the tables of a relational database using the metadata that describes the mapping between the objects and the database. ORM stands for Object/Relational mapping. Interceptors in Hibernate ORM Framework.Introduction to Hibernate ORM Framework.If you are looking to study more details on hibernate, please read the below articles: Having good knowledge on database is added advantage to write the more efficient hibernate programming. It is a beautiful approach for persisting into database using the java objects. Hibernate eliminates developers to spend more time on writing the native SQL queries and understand the complete underlying database persistence mechanism. This lets the users to develop persistent classes following object-oriented principles such as association, inheritance, polymorphism, composition, and collections. Hibernate is a powerful, high performance object/relational persistence and query service.
