Чем отличается JDBC от Hibernate?
Ответ:
При использовании JDBC разработчик сам управляет соединениями, пишет SQL, обрабатывает ResultSet, а в Hibernate всё это абстрагируется: объекты автоматически мапятся на таблицы, запросы могут писаться через HQL или Criteria API, а управление транзакциями и кэшированием встроено.

In recent times, Telegram has gained a lot of popularity because of the controversy over WhatsApp’s new privacy policy. In January 2021, Telegram was the most downloaded app worldwide and crossed 500 million monthly active users. And with so many active users on the app, people might get messages in bulk from a group or a channel that can be a little irritating. So to get rid of the same, you can mute groups, chats, and channels on Telegram just like WhatsApp. You can mute notifications for one hour, eight hours, or two days, or you can disable notifications forever.
A Telegram spokesman declined to comment on the bond issue or the amount of the debt the company has due. The spokesman said Telegram’s equipment and bandwidth costs are growing because it has consistently posted more than 40% year-to-year growth in users.
