Our Physical Design Work for the OnCD application included deployment diagrams, Database Schema and glossary.

We divided the tasks to each person. Lucheng did the deployment diagrams which show how and where the system is to be deployed. In another word, it shows the execution architecture of OnCD application. We created a simple deployment diagram to represent the arrangement of web server, credit card system, database server and web server. The servers were represented with different components and linked by communication paths.

A database scheme can be designed for database administrators or developers to quickly get started learning the basic objects information about OnCD application in real-world environment. Joe made a excel spreadsheet to show the objects information stored in the database, such as customer, staff, vendor, digital music file, CD album, order and payment.

We also had a detailed glossary called Data Dictionary which was made by Joe. This is the place to find out all the terms covered on the system. There were 39 relating terms with an alphabetical listing and descriptions.
