I am assigned a task which is related to designing a database for a university. Which SQL data type should I select to store the ID numbers of the students, their date of birth, and their course enrollment status?

In the context of SQL you can select the valid SQL type for Students ID number. The valid SQL type for this purpose could be VARCHAR or JNTEGER, depending on whether the ID is numeric or alphanumeric. On the other hand, you can choose or utilize DATE for the date of birth. Moreover, for enrollment status, you can use the BOOLEAN data type if it is just a simple truth or false indicator. If there are predefined values presented such as enrolled, dropped, or completed then you should utilize ENUM in this case.

Here are the instances given as SQL queries:-

CREATE TABLE StudentInformation (

        StudentID VARCHAR(20),

        DateofBirth DATE,

        CourseEnrollment BOOLEAN

);

This above coding analogy showcases how you can utilize various methods mentioned above to create a dataset regarding the students of the university.
