What is a CRM?
Customer Relationship Management software.
A CRM is a system which is designed around the concept of managing a customer's transactions with an organisation. There are many commercial CRMs such as: Salesforce, Northgate, CareFirst. The principle of a CRM is to have one instance of a customer and then 'hang' all information, transactions, contact history, etc on that customer record. There should be one customer to many transactions.
