Simple Address Book Version 2.0w

Simple Address Book implemented using a multi-layer architecture and interfaces to use each layer.
This version of the project has about 6 weeks of part-time effort to give you a great start/guide on your projects.

Contacts are stored in two separate tables for the person information and the address information. The records are related by the person’s id field using the ContactService business logic (not the database). Each person can have only one address.
This application allows you to save, get, delete, or list contacts.
