What Is Hibernate Framework and How Does It Work?

What Is Hibernate Framework and How Does It Work?: Hibernate Framework is a free, open-source object-relational mapping library in Java. It is specifically designed to connect objects to RDBMS and implement notions of object-oriented programming within a relational database. Hibernate framework Hibernate architecture is designed in a minimal way and has built a layer between the applications and database. The entire detail of mapping databases, connecting strings for databases entities classes, and other data are loaded and synchronization is made with the database as well as the application through Hibernate.

Hibernate databases are strong and secure, too it is able to be used in a variety of ways. This is why our developers utilized the Hibernate framework that has been carefully developed and designed Hibernate annotations to keep your database secure and safe.

Understanding Hibernate Framework 

A. Definition and Purpose

Hibernate, at its core, aims to alleviate the complexities associated with database interactions in Java applications. By providing a framework for mapping Java objects to database tables and vice versa, Hibernate simplifies the data handling process, promoting cleaner and more maintainable code.

B. Key Features

1. Object-Relational Mapping (ORM)

One of Hibernate’s defining features is its ORM capability, which allows developers to work with objects in code rather than dealing directly with database tables. This abstraction fosters a more natural and object-oriented approach to programming.

2. Cross-Database Portability

Hibernate’s support for multiple databases ensures portability, enabling applications to seamlessly transition between different database systems without major code modifications.

3. Automatic Table Generation

Hibernate can automatically generate database tables based on the entity classes, eliminating the need for manual table creation and maintenance.

C. Comparison with Traditional JDBC Approach

Unlike the traditional JDBC approach, where developers need to write complex SQL queries and handle result sets, Hibernate abstracts these operations, allowing developers to focus on business logic rather than low-level database interactions.

What are the advantages of using Hibernate?

Hibernate provides several advantages over traditional JDBC, such as:

  1. Increased productivity: Hibernate simplifies the development process by providing an abstraction layer on top of JDBC, which reduces the amount of boilerplate code required to interact with the database.

 

  1. Platform independence: Hibernate is database-independent, which means that it can work with different databases without any changes to the code

 

  1. Simplified transaction management: Hibernate automatically manages transactions, which reduces the amount of code required to handle transactions.

 

  1. Improved maintainability: Hibernate provides a clean separation between business logic and persistence logic, which makes the code more modular and easier to maintain.

 

  1. Increased performance: Hibernate provides several performance optimizations, such as caching and lazy loading, which can improve application performance.

 

What is Hibernate Framework Architecture

What is Hibernate Framework Architecture: Hibernate is a multi-layered system which allows the user to work without needing to be aware of the API’s. The Hibernate framework architecture has various objects, including session factory, persistent object and transaction factory, as well as connection factory sessions, transactions, etc.

What Is Hibernate Framework and How Does It Work?

Hibernate utilizes a variety of existing Java APIs, such as JDBC, Java Transaction API (JTA) as well as Java Naming and Directory Interface (JNDI). JDBC provides a minimal degree of abstraction of the functionality similar to a relational database that allows nearly any database that has an JDBC driver to work with Hibernate. JNDI and JTA permit. Hibernate to be integrated into J2EE applications server.

Elements of Hibernate Architecture

Before we can create the hibernate application it is important to understand the hibernate architecture’s elements.

configuration:The Configuration object represents the initial hibernate object that you create within any hibernate application. It’s usually created once in the initialization of an application. It’s a configuration file or properties file that is required by Hibernate.

Session Factory: The Session Factory is a factory of clients and sessions of a connection providers. It stores a second level storage of information. The org.hibernate.sessionfactory interface method to get the object of Session.

SessionThe session objects provides an interface to the program and the data kept in the databases. It’s a temporary object that wraps it around the JDBC connection. Session interface allows you to update, insert and remove the object.

Transaction:The transaction object specifies the fundamental piece of work. It’s not required. The organization. hibernate. Transaction interface is a tool for managing transactions.

query objects: query object uses SQL and Hibernate query language strings to read data from the database and then create objects. The query instances are used connect parameters to the query, restricts how many results are that are returned by the query and lastly, to execute the query.

Criteria objects: Criteria objects utilized to build and execute criteria queries that are oriented towards objects to find objects.

The reasons to select Hibernate over JDBC

JDBC is the abbreviation in the acronym Java Database Connectivity. It is a completely free and open source API for application development in Java that allows applications to connect with databases. It allows developers to build queries and then update data into an existing database by with the help of structured query languages (SQL).

  1. Map of Objects: In JDBC, you must write code to convert the object model’s information representation to a relational model and the schema that corresponds to it. Hibernate can map Java classes to tables in databases via XML or using annotations.

 

  1. HQL: Hibernate uses HQL(Hibernate SQL Language) that is akin to SQL however Hibernate’s HQL offers full support for polymorphic queries. HQL comprehends concepts of object-oriented nature such as inheritance, polymorphism, as well as the concept of association.

 

  1. Reduce Code Changes: Hibernate reduce code changes whenever we add a column to the database table.

 

  1. Reducing Repeat Code: JDBC throws SQL exception, which is a an exception that is checked. Therefore, you’ll be writing “try-catch” blocks in your code. Hibernate manages this by changing all JDBC exceptions into unchecked exceptions. So, you don’t need to delay implementing the try-catch block.

 

  1. versioning: Database Versioning of data is an essential feature of Hibernate. Hibernate framework allows developers to define a version type field within the application. The field can be updated whenever data is updated each time. The benefit is that when two users access identical data, and later modify the data, and one of them saved the modified data to the database prior to another uses it, the version is modified. The other user attempts to save their data, the database is not allowed because the data isn’t in compliance with data. In JDBC this test is carried out on behalf of the developers.

Conclusion

It’s now obvious that Hibernate framework can definitely improve the efficiency of your application and decrease the development time of your application, and consequently the price. In light of the benefits mentioned above I would recommend all users use the Hibernate framework instead of JDBC.
