Dave Hay commented on my post How Many Attributes Do I Have?   Dave notes that there is a difference between me and the roles that I play.  This is an important point that I struggled with previously.  Dave states "most of the examples are attributes of my role as a customer", meaning the examples I provided in my post. "Role" is a term that gets bandied around a lot in data modeling.  In my previous post on Role vs. Relationship I argued that roles really refer to certain kinds of relationships.  However, Dave's point is one that I have heard on a lot of occasions and has to be taken seriously. Let's state the question this way: is the attribute Customer Lifetime Value to Hardbitten Liquors an attribute of me, or an attribute of my role as a customer of Hardbitten Liquors?  And if the latter, just what do we mean by "role". There is no doubt that I am an instance of a concept.  The concept is human being.  Further, Customer Lifetime Value to Har...

Most of my experience in doing definition work has mostly been from the perspective of an analyst involved in systems development.  These days it usually data-centric applications, such as building Master Data Management (MDM) or business intelligence (BI) environments.  The method of the analyst begins with understanding scope and requirements, and then finding the business concepts and data objects that need to be defined. However, there are other perspectives.  Terminologists, often oriented to the language translation industry, do deinition work.  So, I suspect, do brand managers, who want to control messaging to customers. I work a good deal in financial services, and I am aware that there is another group that gets involved in definitions.  These are business people who create completely new products.  For instance, Asset Backed Securities (ABS) and Colladeralized Debt Obligations - both now notorious as weapons of mass financial desctruction - were c...

Charact eristics of a concept - its attributes - are central to definitions.  But to what extent should the characteristics of a concept be listed in its definition?  Should it be few, or some, or as many as possible?  As a step in beginning to answer that question, I think that we need to ask if we can reliably determine all the characteristics that a concept possesesses.  And I now intend to see if I can answer that question by finding out if I can list all the attributes that I possess. I am aware that I am an instance and not a concept (at least a general concept).  However, I would submit that there is a prima facie case that I should be able to provide a list of my attributes.   If such a list could be produced, then we couldn see if the attributes apply to the concept I am an instance of (humans).  We could then move on to figuring out what attributes should or should not be included in a definition.  But, if I cannot even r...
