hari ini ada yg nanya tentang teori struktur navigasi di website yaitu linier, non linier, hierarki dan komposit. gw coba cari tahu via googling pake keyword "linear navigation structure". inilah hasilnya:

- linear navigation pattern

- hierarchy pattern

- composite pattern

nah yg non linier ini gw ga nemu
mungkin maksudnya : random access structure kali
