![]() ![]() ![]() Inheritance: Hibernate supports various inheritance mapping strategies, including single table, table per class, and joined strategies.ī. How does Hibernate support Object-Oriented Programming concepts in persistence?Ī. Hibernate provides additional features and optimizations beyond the JPA specification.ħ. JPA is a standard specification for ORM in Java, which defines a set of APIs and annotations for persisting objects.Ĭ. Hibernate is an ORM framework and a specific implementation of JPA.ī. This is a very important and useful question in the "hibernate interview questions and answers" if you want to know if your conceptual foundations are in order. What are the differences between Hibernate and JPA? If any changes are detected, Hibernate automatically generates and executes SQL update statements during the transaction commit.Ħ. Hibernate tracks the state of objects in memory and compares them with their original state when the session was opened. Can you explain the concept of Dirty Checking in Hibernate?ĭirty checking is the process of detecting changes in persistent objects. It offers less abstraction and more control over SQL queries than Hibernate or JPA.ĥ. MyBatis is a lightweight, SQL-focused persistence framework. JPA (Java Persistence API) is a standard specification for ORM in Java. Hibernate is a full-featured ORM framework that provides a high-level API for data persistence.ī. How does Hibernate compare to other ORM frameworks like JPA or MyBatis?Ī. Hibernate uses JDBC to execute SQL queries, manage transactions, and handle other low-level database operations.Ĥ. JDBC (Java Database Connectivity) is the underlying technology used by Hibernate to interact with databases. Generating SQL queries automatically, which helps to avoid the need for manual query writing.ģ. Using a flexible mapping mechanism, allowing you to map Java objects to database tables and columns using XML files or annotations.Ĭ. Providing an abstraction layer through dialects, which allows Hibernate to adapt SQL syntax for different databases.ī. Hibernate handles database independence by:Ī. How does Hibernate handle database independence? Transaction management: Hibernate provides seamless integration with Java transaction APIs.Ģ. Support for complex associations and inheritance: Hibernate simplifies the management of complex relationships and inheritance hierarchies.į. Lazy loading: Hibernate supports lazy loading of related entities, which improves performance by loading only the required data.Į. Caching: Hibernate has built-in caching mechanisms to optimize query performance.ĭ. Database independence: Hibernate supports various databases and provides an abstraction layer, making it easy to switch between them.Ĭ. Improved productivity: Hibernate simplifies the code needed for CRUD operations, which reduces development time.ī. The most important reasons to use Hibernate as an ORM system are:Ī. What are the main advantages of using Hibernate as an ORM framework? In the relational database, more than one row of one entity can refer to more than one row of another entity.1. ![]()
