Assalamualaikum you olls. Haa kenapa nilai? Bukan Nilai dekat N. Sembilan ye. Haha. Chapter seterusnya ni pasal value. Sebab tu ceq cakap pasal nilai. Nowadays, kita boleh dapatkan information tu kat mana mana. Even, lepak kat kedai mamak pun kita boleh dpt information. Hebat tak teknologi skrg ni?? information tu boleh kita dpt dr nilai besar smpai la ke yang palinggg simple tiny things!

Ada dua jenis value of information sebenarnya. Okay, kalau transactional, mesti la ianya berkaitan dengan pertukaran. Sama ada pertukaran dr segi jual beli. Kita beli brg then dapat receipt. Haa tu kan transactional info jugak.

Okay, kalau analytical pula, ia berkaitan dgn analysis la of course. Mostly, kita buat statistic about article tu. Sama ada nak analyze utk future.
Nilai information yg kita dapat mestilah berkualiti. Semua org nak dapat sesuatu tu dgn berkualiti, in good condition right? same as information laa. Quality information must be accurate, timeliness, uniqueness and many more.
