online Application Design in ppt

The main "point" that has to be made with application design is that application design can be a performance issue. 

That is right, the way that your front-end and back-end interact can change how good the efficiency of your system is

 

the biggest thing is that we need to make sure that our front end has spaces for each one of these fields. the front end is the way your user interacts with your database....period. If there isn't a screen to enter grades, then that student is not going to be entering a grade.

 

On the flip side, you can't see that your system is going to generate a schedule for a student and not have the fields in the back end, it just doesn't work. Thinking about an application is very much an HCI (human computer interaction) way of thinking.

Make sure you include a "clean" page of the screen you are designing as well as a "marked up" version that shows which field the text field (or other thing) is related to as well as a description of the queries that would run if the button was hit

 

Take for example this student registration system (Here is the schema for this example
