$($iii$)$ In recent years, less $$record$-$oriented$$ data, such as internet $($website and web pages$),$ social media $($blogs$,$ chats, etc.$),$ multimedia $($photographs$,$ videos, text messages, etc.$),$ scientific $($experimental data$),$ and engineering $($designs and manufacturing$),$ are collected in large volumes on computer servers. Yet, most $($if not all$)$ current commercial database management systems are relational, which was developed to deal with record data of rows and columns.

Is the relational model still sufficient in representing the ever increasingly diverse structures of data we collect these days? Discuss.
