Hibernate features

1.?Lightweight

Hibernate is a lightweight framework as it does not contains additional functionalities; it uses only those functionalities required for object-relational mapping.
It is a lightweight framework because it uses persistent classes for data transfer between java application and databases.

2?Open Source

Hibernate is open-source software that means it is available for everyone without any cost. Its source code is made available so that anyone can use and develop applications using hibernate.
It can be downloaded from its official website, hibernate.org. The latest version a user can download is Hibernate 5.4.

3?ORM (Object Relation Mapping)

Hibernate is an ORM tool which helps in the interaction between the java classes and relational database.
It also solves the problem of data mismatch found in Java application and RDBMS.

4?High Performance

Hibernate supports many different fetching techniques such as, caching, lazy initialization, and many more to achieve high performance.

5?HQL (Hibernate Query Language)

Hibernate has its query language, i.e., HQL (Hibernate Query Language) which is independent of the database.
HQL is an object-oriented language similar to SQL, but it works with the persistent object and its properties.

6?Caching

Hibernate supports two levels of caching, first-level and second-level caching.
Caching is the process of storing data into cache memory and improves the speed of data access.

7?Auto-Generation

Hibernate provides a feature of automatic table generation. It means a programmer need not worry about the query implementation, i.e., Hibernate does on its own.

8?Scalability

Hibernate is highly scalable as it can be fit in any environment. Hibernate can be used for both small scale and large scale applications.

9?Lazy Loading

Hibernate supports a new concept called lazy loading. Lazy loading concept retrieves the only necessary object for execution.
It also improves the performance of an application.

10?Easy to learn

Hibernate is easy to learn and implement. It is developer-friendly as it takes care of the changes made to the database automatically, so it reduces the developer’s work.

11?Database Independent

Hibernate is database-independent as it provides ‘Database Dialect’ so we need not write SQL queries.
?It supports many databases such as Oracle, MySql, Sybase, etc.t
