In the video, Dave creates a separate program file from the data file (students). How is the program file able to access the students file data? I saw that he adds the link in the html.index page but is that really it?

You are indeed correct. It's these two lines that allow the JS code to work together:
<script src="js/students.js"></script>
<script src="js/student_report.js"></script>
You'll notice that in students.js an array of objects is assigned to a variable named students (plural).
This is then used within the for loop inside student_report.js:
for (var i = 0; i < students.length; i += 1) {
student = students[i];
if ( student.name === search ) {
message = getStudentReport( student );
print(message);
}
}
Using multiple script tags your HTML file allows you to not only include other libraries (such as jQuery), but it also allows you to break up your code.
Hope that helps!
