Do we have to use transaction every time while using with hibernate?

I had read many websites and they says that using transaction is optional as hibernate application manages transaction in their own application code.

But when I check code it always uses transaction?

What is the correct methodology?

    Configuration c = new Configuration();
    c.configure("hibernate.cfg.xml");
    SessionFactory sf = c.buildSessionFactory();

    Session s = sf.openSession();

    Transaction t = s.beginTransaction();
    //some code
    t.commit();

Add the following tag in hibernate property file

 <prop key="hibernate.current_session_context_class ">thread</prop>

or if you are using spring, then you can use @Transactional annotation to handle the transaction automatically.

Here's what the official documentation says:

Database, or system, transaction boundaries are always necessary. No communication with the database can occur outside of a database transaction (this seems to confuse many developers who are used to the auto-commit mode). Always use clear transaction boundaries, even for read-only operations. Depending on your isolation level and database capabilities this might not be required, but there is no downside if you always demarcate transactions explicitly. Certainly, a single database transaction is going to perform better than many small transactions, even for reading data.
