Um...wow.
Good thing you can have 13 months!
My favorite part of all is that it's called "Intact." That just seems like a misnomer to me.
Industry specific software

ours is equally shit, and funny enough also allows 13 months on the accounting side, there must be something I'm missing. I think ours has around 500 tables spread over 2 dbs, field naming is proper fun; Customer_AC_No, Customer_AC, Customer, Customer_No, Customer_A_C_No, could be anything, and the account side uses different numbers to refer to customer or supplier accounts.
Then there's all the mispelled field names; Invoce_Number, Style_Desciption, Transcation_Quantity...
And all the broken functionality that apparently NONE of their other customers have encountered, ever.
I'm crap at SQL/db admin, and even I figured out that adding some indexes might improve performance.
A similar screen to Sein's in our system would be spread over around 10 tabs, tab title having no apparent influence on the tab contents
