Hello, this is just teorethical question.

I use JDBC with my Java applications for using database (select, insert, update, delete or whatever). I make "manually" Java classes which will contain data from DB tables (attribute = db column). Than I make querys (ResultSet) and fill those classes with data. I am not sure, if this is the right way.

But I've read lot of about JDO and another persistence solutions.

Can you please recommend some?

Which are modern? Will be used in the future?

Some advantages of JDO over JDBC (in simple words).

I've been able to google lot of this stuff, but opinions from the "first hand" are always best.

Thank you for responses, Mike
