Unit 6 Assignment 1
Application 1: Data
Modeling
In your earlier analysis efforts, specifically
in structural modeling, you examined the organization of data within a system.
The approach that you used in analyzing that data structure was an object-oriented
approach. In this Application you use a structured approach to model the data
flow processes as you develop the data aspect of your design.
Consider this scenario: Quality Tools is a
company that sells a line of high-quality tools through an online store. When
customers place orders on the company’s website, the system checks to see if
the items are in stock, issues a status message to the customer, and generates
a shipping order to the warehouse, which fills the order. The system automatically
bills the customer when the order ships. The system also produces various
reports.
For this Application, perform the following:
·
Draw a context diagram
for the order system.
·
Draw a Level 0 DFD for
the order system.
·
Justify the choices
you made in your context diagram and DFD.
·
Briefly compare the
structured approach you use here with the object-oriented approach outlined in
your reading.
Cite your sources according to APA guidelines.
Submit your assignment by Day 7.
