Data Modeling
Assignment 1: Data ModelingIn 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 read :https://en.wikipedia.org/wiki/Data_modeling
