Question

The animal shelter requires that people who volunteer there affirm that they are not allergic to dogs or cats. How would you modify the database schema so that this information could be included?

Answer 1

Answer:

With the use of YES or NO question to ask prospective volunteer "Are you allergic to dogs or cats?"

Explanation:

the data base schema is the organisation and structure of a database. the data base schema would be modified into a closed ended question asking each volunteer whether or not they are allergic to cats and dogs to define their allergic status before they work in the shelter. Volunteers must then choose either YES or NO to establish whether or not they are allergic to dogs and cats.

Answer 2

Answer: Through the use of close-ended questions, for example a question with a YES/NO answer.

Explanation:

Close ended questions are questions in which a participant has already been provided with options to a question, and so the participants must choose from the options and cannot give an answer outside the options given.

Using this kind of question to modify the database schema would be helpful.

Therefore, in order to affirm that the volunteers are not allergic to dogs or cats, the close ended question "are you allergic to dogs or cats" can be used. The volunteers would be provided with a yes or no answer which they must choose from.

This would help in modifying the database schema while affirming whether the volunteers are allergic to dogs or cats.
