When I want to edit code in OpenERP, is it possible to save one piece of data in two databases where the fields have the same names in both tables.
Yes it is quite possible if you know the database but let me warn you this is very bad idea cause it is very risky and all rule of Resistance layer (ORM) will be violated.
What are you actually trying to do?? If you are trying to synchronize, then use the module base_synchro. The module is not complete. You have to do your own customization in that module
