Example of DFD for Online Store (Data Flow Diagram)

Data flow diagrams (DFDs) reveal relationships among and between the various components in a program or system. DFDs are an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations.
Example of DFD for Online Store shows the Data Flow Diagram for online store and interactions between the Visitors, Customers and Sellers, as well as Website Information and User databases.

This AD diagram example was created based on the picture "AD LDS as a phone book service" from the book "Active Directory for Dummies".
"Directory services are a great way of providing information that can be fre-
quently retrieved and searched on in a hierarchical way. ... Well, there’s no reason that you can’t create a directory service that’s actually a phone book. Imagine that you need to make a searchable phone directory of your organization available on the Internet. ... This isn’t a difficult task, but it has security repercussions. If you’ve already deployed AD DS and you have the employees’ phone numbers available in that directory, it might not be a good idea to expose your AD DS environment to the Internet for security reasons. Using AD LDS is a great alternative because it can be deployed separately from AD DS and it’s designed to simply provide the information retrieval service that you need without the complications involved with Kerberos authentication and group policies." [Steve Clines and Marcia Loughry, Active Directory® For Dummies®, 2nd Edition. 2008]
The Active Directory diagram example "AD LDS as a phone book service" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Active Directory Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.
