From the above-mentioned points, it is crystal clear that Hibernate will definitely increase the performance of your application and help you to reduce the development time for your application and hence the cost.

Hey Java Developer, Have you ever feel irritated by repeating the same lines of code over and over again in your application for fetching data from the database? Are you struggling to map objects to your database tables?
Is it difficult for you to implement oops with your JDBC code? Does it takes too much of rework while migrating from one database to another?
Have you ever found it difficult to create associations between tables using JDBC? What is JDBC? JDBC Workflow. Source: avaldes. Opens a database connection Sends SQL queries to database using a JDBC driver JDBC driver connects to database Executes the queries to get the result set Sends the data to the application via the driver manager When results are returned, then it processes the data Finally, the connection is closed.
What is Hibernate? Source: J2eebrain. Hibernate Workflow. Source: Cloudsopedia. The results are mapped to objects based on the properties given in the Hibernate configuration XML file. The database connection from an application is created using session which also helps in saving and retrieving the persistent object. Session factory is an interface which helps to create an instance of a session. There must be only one session factory per database.
There will not be more than one session factory per MySQL alone. Hibernate mainly solves the object-relational impedance mismatch problems which arise when a relational database is connected by an application written in object oriented programming language style.
Object-relational impedance mismatch includes mismatches arises due to data type differences, manipulative differences, transactional differences, structural and integrity differences. Click here to see more details. Hibernate itself maps the Java classes to the database tables using XML configuration or by using annotations.
HQL understands object-oriented concepts like inheritance, polymorphism, and association. It is achieved by using a dialect to communicate with the database. The database can be specified using dialect in the Hibernate configuration XML as follows. You need to fetch the first 10 entries of a table. It is very much popular in between all the available object-relational mapping tools.
JDBC is mainly used for static application or some legacy application where migration is too costly. People are normally preferring to using JDBC for some time on a small project or preparing manual object-relational mapping architecture for using in some big project. All the proper aspect of Hibernate can be reachable by JDBC doing some manual development which is too costly for any developer.
Hibernate caching mechanism is too much simpler than any other ORM tool available in the market. Hibernate mainly popular with the developer due to this extraordinary features. It always helps to improve the performance of the application, as this mechanism helps the application to reduce the frequency of creating a connection with the database every time.
It holds data into a memory cache, which can be utilized for a later point of time in the entire application as per requirement. Cache data can be refresh by reloading those hibernate objects. All the ORM objects hold those cache data, which helps the application to reuse those data easily without several interactions with the database. Object-relational mapping and criteria can able to resolve all the SQL query related requirement until it has one HQL concept. More often than not, you will like to detect changes in the database.
The debate will keep raging between JDBC vs. However, it is a bit slower performance-wise in comparison to JDBC. Depending on the requirement of your project, you can choose the most suitable option.
