I want to know is there any difference in catalog and 开发者_C百科eav tables of magento 1.4.1.1v and magento 1.5v. Difference in the sense, are there any fields are added or removed in catalog, eav tables?
I would install fresh copies of both 1.4 and 1.5, then do a structure-only dump (phpmyadmin can do this too) of the databases, then Diff the resulting SQL files. This will show you the differences.
Here are a ton of other options to compare two MySQl DBs: Compare two MySQL databases
Cheers
