I would like to recreate the forms my way to acces this DB and get the informartion the way i want.
What do you mean by "the way I want"?
The first thing you need to understand about Oracle Forms is that it is tightly integrated with the Oracle Database (RDBMS); meaning you can't use Forms to directly connect to any other database except an Oracle Database. Also, since Forms is tightly integrated with the Oracle RDBMS it (Forms) will handle many standard DML operations for you; such as Querying a record, Update of an existing record or Insert/Delete of a new or existing record without you (the developer) having to write a single line of code to handle the DML.
Hope this helps,
