Question
Chapter 7, Problem 11RQ
Program Plan Intro
“DATE” data type:
This data type is used to store date and sometimes, time values. Usually DBMS stores the value of date in the numeric format according to the Julian calendar. The format to store date is “YYYY-MM-DD”.
Syntax:
CREATE TABLE table_Name(column_Name DATE);
Expert Solution & Answer
Explanation of Solution
Using “DATE” data type than character data type:
It is preferable to use “DATE” data type than character data type because,
Database Management System (DBMS) does not distinguish numeric values if character data type is given.- It is not possible to add and subtract the date arithmetic if character data type is given.

JAVA Script
Create a form that has a last name, a first name, an email address, a drop-down listing of 10 cities in Massachusetts. The list is to be sorted (hint: think array), an email address, and a zip code field. Each field is to be process through a validation function. You may use one function for each but if you are creative you should be able to use just one function. The drop-down listing will not require validation because they will be choosing from a list that you are providing.
This input from must be styled and show an effect to the user as to which field that are currently providing input.
