For example, the shared Oracle Clusterware files (OCR and voting files) and all physical database files in this article will be set up on only one physical disk, while in practice that should be configured on multiple physical drives.
The list of contacts will be displayed and user will be able to delete existing contacts. We will have a layered architecture for our demo application.

For our Contact Manager example, we will use My SQL database. This is very preliminary example and thus we have minimum columns to represent a contact.
Feel free to extend this example and create a more complex application.
