Mapping tables from an existing database to an object - is Hibernate suitable?

Question

I have several tables in an existing database and I want to map them to a Java object. In fact, this is one table that contains basic information, some other tables that refer to such a table entry with a foreign key.

I do not want to store objects in the database, I just want to read them. The program should not be allowed to apply any changes to the underlying database.

I am currently reading from a database with 5 SQL JDBC queries and setting the results then to an object.

Now I am looking for less intensive code. Another goal is the educational aspect. Is Hibernate suitable for this task or is there another ORM framework that better suits my requirements?

Sounds like a standard circuit, Hibernate should be able to handle it without a problem.

Hibernate supports “immutable” objects (immutable objects cannot be updated by the application, see @Immutableannotation).

If you are looking for a simpler hibernation solution, you can check out ORMLite, which is a [very] simple ORM package. I used it to read in objects from existing SQL tables with great success.
