Data models do present a filtered and incomplete representation of a business area. A data model is a set of symbols and text for representing information in an easy-to-understand way. An easy-to-understand visual, however, focuses only on information and ignores other useful characteristics of the existing or proposed system, such as the business process. For example, a data model will capture that a customer must own at least one account, but not capture the process of how that customer opened their account.
