Question: //Database Management, Serializable Schedule Note: T < number > identifies a transaction numbered number . R( < letter >) identifies a read operation on database
//Database Management, Serializable Schedule
Note: T<number> identifies a transaction numbered number. R(<letter>) identifies a read operation on database object letter. W(<letter>) identifies a write operation on database object letter.
Consider the following schedule:
T1: R(A), T2: W(A), T3: R(A), T1: W(B), T3: R(A), T2: R(B), T2: W(B), T3: R(B), T3: W(B), T2: R(C), T1: R(C)
Is the schedule serializable? If so, show an equivalent serial transaction order. If not, precisely describe why not.
If relevant, fill in this table with the equivalent serial transaction order. Time proceeds from left to right, with only one action possible in each time slot.
| Serializable Schedule | Time 1 | Time 2 | Time 3 | Time 4 | Time 5 | Time 6 | Time 7 | Time 8 | Time 9 | Time 10 | Time 11 | Time 12 | Time 13 | Time 14 | Time 15 |
