Minimize the following DFA: 0 1 →90 q1 90 91 qo 92 92 93 91 *q3 93 90 94 93 95 95 96 q4 96 95 96 q7 96 q3 Hint: Use the "table filling method" for minimizing your DFA (if needed).

What is the most efficient way to write a trigger that updates a large number of rows?     Specify "for each statement"     Specify "for each row"     Specify "for each table"     Specify "referencing new row"
