Thanks for letting others too know Sachin. It will help community to grow and clear rounds 🙏 means a lot

[@sanskritinannore7209]

Great video, one thing I would like to point out is that we should close the session object first and then close the factory instance. So in the code at 6:45 it should be session.close(); factory.close(); Closing the Session first ensures that the resources (like connections) it uses are properly released back to the pool managed by the SessionFactory and we don't run into any other issues since session uses the instance of session factory for its operations.

All the concepts explanations were really wonderful. Could learn in-depth about each and every concepts. Really Thanks a lot. Only concern is formation of playlist. videos from all the topics were repeated in each playlist. It's quite confusing and difficult to maintain with the flow. Please segregate the videos based on Languages and put it in the playlist for easy flow.

Yes, we understand the playlist is not at all in place. We will try to arrange it as soon as possible. Thanks for the suggestion, we will let you know once we have arranged them.

[@Preethipree1]

Hi, Hibernate and JPA differs only in configuration is it? Hibernate uses Hibernate.cfg.xml file for getting credentials to establish a connection to db. But JPA uses application.properties file to achieve the connection establishment right? Could you please also say how both are differing? Hibernate vs JPA.

[@CodeDecode]

Hibernate is implementation of jpa. Jpa is just a standard, hibernate has orm / jpa implementations

[@AshutoshMohanty07]

Thanks for the in-depth analysis. By far the best simplified explaination video on youtube for Hibernate. One doubt, If i am using Hibernate configuration java class & using annotations(@Entity, @Table, @id,@Column) for the java POJO class and fileds. Do i need to create the Java POJO xml mapping class separately ?

[@CodeDecode]

No you don't. Bcz with xml u create bean @entity creates bean only. So no

Hi team Code Decode, may i know these questions are sufficient enough for a person having 3 to 4 years experience

[@CodeDecode]

It's part one. These are frequently asked questions that tests your base knowledge. Hibernate is a very indepth topic which I can cover in parts. So it's just the first part and Yes it will help you to answer the questions if interviewer try to know if you have ever worked on it or you have just bookish knowledge.

[@CodeDecode]

Sure Venkat. We will do that👍🙂

[@gokulaher2476]

What is hibernate mapping file? (While watching answer to this question I got few questions) Well! Do we really still use XML based configuration file in real world application? is Hibernate mapping using XML file is outdated? Annotation based mapping is mostly preferred in real world application right? barring that your way of explaining concept is simple and easy to understand I think it would have been better if annotation based mapping is also mentioned along with XML based
