What is hibernate tool

It simplifies the interaction of a database and the Java application being developed. It is an ORM tool that is powerful and lightweight. Another important thing is that this is an open-source high-performance tool. Hibernate implements Java Persistence API specifications and is a very powerful object-relational persistence and query service for applications developed in Java.

Java objects and database server interacts with each other via Hibernate. The architecture of Hibernate is layered such that the user does not really need to know the underlying APIs in order to operate.

It is with the help of the database and configuration data that the Hibernate is able to provide persistence services and objects to the application. The architecture of Hibernate consists of objects like a session factory, transaction factory, persistent object, etc. Hibernate framework uses many objects such as session factory, session, transaction, etc. In order to retrieve data from the database writing repeatedly the same lines of code in your application again and again can be tiring and irritating.

An editor helps code looks clean and understandable by various formatting options defaulted. It supports auto semantic completion by suggesting column, table, row names based on the usage history.

It is used to generate an artifact based on the hibernate model. Hibernate tools come preloaded with a code generation launch template in which one can take a configured hibernate model and use it for various code generation tasks.

Hibernate tools support various major versions of hibernate to provide the flexibility of its usage in the nay version stored. To check the data extraction queries HQL and fetch the real-time results we can make use of the console. The console is used to display the results after running the queries. The hibernate console helps by providing visualizations of database connections, classes, and their relationships. The console can be used to derive the changed results as per queries HQL change database query.

This tool enables the function of generating domain model classes, mapping files for hibernating, annotated entities from EJB3 entity beans, HTML codes and many more things. This provides control over various aspects involving the translation of data from the database to the persistence objects in the front end. Forex: How tables containing one to many relationships should be detected and its mapping should be done as one to many or some other mapping instead. It can also provide more control over this translation process with the help of a reveng.

This is an extended feature of the hibernating console. One can visualize the mappings using this tool. This tool can be accessed using a hibernate console window. The Hibernate Console perspective allows you to configure database connections, provides visualization of classes and their relationships and allows you to execute HQL queries interactively against your database and browse the query results. The most powerful feature of Hibernate Tools is a database reverse engineering tool that can generate domain model classes and Hibernate mapping files, annotated EJB3 entity beans, HTML documentation or even an entire JBoss Seam application in seconds!

Several wizards are provided, including wizards to quickly generate Hibernate configuration cfg. The Hibernate tools include a unified Ant task that allows you to run schema generation, mapping generation, or Java code generation as part of your build.
