Evaluate the decision table below:
What “hit type” should be associated with this table to ensure that each student is given a single, correct Admission Status?
- Single hit, unique
- Single hit, first
- Multiple hit, output order
- Multiple hit, rule order
You answered: D
Correct answer: B
Processing sequence is implied here. Specifically, this table only works if you process starting with the top row and work your way down, stopping at the first row where you satisfy the conditions. Therefore, in order to correctly interpret the table, we must identify it as a “single hit, first” table.
The table cannot be identified as a “single hit, unique” table type, because a student with an 80% ranking meets conditions in multiple rows.
It is not a multiple hit table because we only want to assign one Admission Status to a student. Using the example of a student with an 80% ranking again, a multiple hit table of any type would return more than one Admission Status.
