Hello? I am familiar with Java Hibernate ORM and Oracle. I understand your trouble. ORM offers many functionalities, but is originally slow due to many asyncronous functions. Your selection is right. I will help you build your idea as much as possible. If you discuss more about it on chat, you will feel how about my skills. Looking forward to meeting you again on chat. Regards. From <Yongde>

The performance of the system is not affected by whether Hibernate or pure SQL is used. The SQL query itself affects the performance of the information system, how well the indexes and the SQL query logic itself is built. The SQL logic of the query does not change if Hibernate or pure SQL is used. In the end, the Oracle server still receives a pure SQL query, and if it is not efficient, there will be slowdowns up to hours and even days. Contact me, I will deal with your problem, if you want to write everything in pure SQL or I can deal with Hibernate and fix errors in it. Hibernate is very useful when you work with several different types of SQL servers, and if only with Oracle, then pure SQL is much simpler and better.
