Account

•The THING we use to measure a relationship is called an ‘Account’.

•The Account is the object that provides a context for the relationship.

•Actually, the Account IS the relationship. Its fundamental function is to aggregate all of the events that transpire between the measurer role and consumer role within the relationship. That is, the Account relates to every transaction with the measured.


	•For example, I purchase gas using my account. That account knows every time I’ve made a purchase. It can tell me the last time I made a purchase and how much I paid. That account can even tell me how much I’ve spent between October 24, 2000 and January 6, 2001.
	•Depending on my criteria as a business, that Account can tell me whether I’m a good Customer, if the business defines a “good Customer” as one who buys more than $200.00 per month and makes the payment on time. Of course, altering the criteria can easily change that policy.
