Assignment 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 Assignment, 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 Assignment, 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. For more information on Data Modeling check on this: https://en.wikipedia.org/wiki/Data_modeling
