Naming and Defining Entities and Attributes › Attribute Definitions

Attribute Definitions

Defining all attributes clearly is important, and the same rules apply. When you compare an attribute to a definition, verify whether it fits well and is not incomplete.

Example:

account open date

The date on which the ACCOUNT was opened. A further definition of what “opened” means is needed before the definition is clear and complete.

Define attributes using the same basic structure as entity definitions. Attribute definitions must include a description, examples, and comments. The definitions must also contain, whenever possible, validation rules that specify which facts are accepted as valid values for that attribute.
