Q$2.$ Transactions$-$Representation $(5$ points$)$

Consider table Item$($name$,$ price$)$ where name is a key, and the following two concurrent transactions.

T$1$:

Begin Transaction;

S$1$: Insert Into Item Values $(\text{'}$FCDB$\text{'},40)$;

S$2$: Update Item Set price $=$ price $+30$ Where name $=$EN$\text{'}$;

Commit;

T$2$:

Begin Transaction;

S$3$: Select Avg$($price$)$ As a$1$ From Item;

S$4$: Select Max$($price$)$ As a$2$ From Item;

Commit;

Map these transactions into the internal Read$/$Write representation.
