Chapter 6, Problem 6DQ
Program Plan Intro
- A database management system is a software package designed for defining, manipulating, retrieving and managing data in a database.
- It acts as an interface between the application programs and physical data files.
- The end user does not have to worry about where and how data is stored with the help of a database management system.
Database design
- Database design involves understanding the relationship among the data, type of data maintained in the database, how data will be used and so on.
- The conceptual and physical designs are two aspects for overall design of the database.
- The conceptual design is the abstract model of database from the business perspective.
- The physical design is the actual arrangement of database on direct access storage devices.

Question 1 - Array Iterators
Like the JS on A2, there is no visual component to this question. The HTML really just needs to load the JavaScript, everything else
will output to the console. The JS file should the completion of the task, and all necessary testing, so that just loading the file will
complete the task with enough different inputs to ensure it works.
Even Numbers [3 marks]
Create a function that determines if a provided number is even. Define an array of numbers, then on the array use the appropriate
array iterator to determine if the array contains only even numbers using the function you defined. Output the results, and test with
several arrays.
Long Names [3 marks]
Define an array of names. Use an iterator to retrieve a new array containing only the names longer then 12 characters. Your iterator
should be passed an anonymous arrow function. Test with several different arrays
First Names [3 marks]
Define an array called fullNames that contains 7 javascript objects of…
