2:again with the column names they should be singular rather than plural, for example StudentCourse not StudentCourses, this will suggest multiplicity and be confusing for the user same should be said for spaces between words and the use of special characters, these too are bad practices.
3: databases without proper documentation for users are also bad practice, so make sure to give ER schemas so users could follow the integrity of data.

Expert Answer
[solved] – Question 70858
Write a servlet that snoops all the information about the current session. Make a “registration” form that collects a first name, last name, and email address. Send the data to a servlet that displays it. Next, modify the servlet to use a default value in form(or give an error message) if the user omits any of the three required parameters.
