Customer relationship management
.
This database design contains enough information to identify who added the customer; what the customer’s interests are; who is responsible for ongoing relationships; when the last contact was and when the next contact should be. The "Contacts History" field can contain a narrative of contacts so far, and because Cardbox lets you index as many words as you like, you can index the date of each successive contact and thus answer, very simply, questions such as "who did Gary talk to in the last week of October?"
