Parsing DBC

Hi guys, I have a question about how to parse DBC to SQL. The main thing is the parts of the data in https://github.com/Aokromes/tc_aowow/blob/master/setup/aowow_sql.php like

nisxxxxxxxxxxxxxxxxx

Or

niiisxxxxxxxxxxxxxxxxsxxxxxxxxxxxxxxxxiiiiisxxxxxxxxxxxxxxxxii

How do they actually obtained? I want to parse 5.4.7 DBC to create AoWoW for 5.4.7 patch

That’s the format identifier of the DBC structure, you get it by trial and error, pretty much, use TOM_RUS’s DBCViewer to try and get it right
