Assignment #04: Customer Relationship Management Tool (CRM)

Implement the Contact Class

1. As a developer, the contact class should have five attributes: "id", "firstname", "lastname", "email" and "notes".
2. As a developer, when a user creates a contact, all five attributes are mandatory.
3. As a developer, I am able to modify those attributes at any point in the program at a later time.
4. The Contact class should also have a method that displays all of its values.

Implement the Database Class

1. As a developer, I should implement the database class as an array that accepts new contacts.
2. As a developer, the database class should have the following methods: "add", "modify_contact", "display_all_contacts", "display_particular_contact", "display_info_by_attribute" and "delete_contact".

Implement the Runner

1. As a user, I am presented with a prompt to 'add', 'modify', 'display all', 'display contact', display attribute', 'delete' and 'exit'.

As a user, if 'no' is typed, I am returned back to the main menu.
4. As a user, if 'display all' is typed, I am shown all of the contacts that exist.
5. As a user, if 'display contact' is typed, I am shown a particular contact.
6. As a user, if 'display attribute' is typed, I am prompted to enter an attribute so that I can see all of the contacts according to that attribute.
