Can there be in whatever way to create a Wordpress blog (or other blog system) and let customers make use of the same qualifications utilized in a phpBB forum...a kind of database discussing.

there is no out-of-the-box approach to discussing PHPBB customers with WordPress - it might involve modifying WordPress a great deal to implement it...

there's a blogging site conversion for phpbb, which converts phpbb right into a blog.. and that i guess you can most likely hack it a little to ensure that you can run forums along with a blog in the same database?
