Q: "What do the different icon icons mean within a Data Model?"
A: Please see table below.
| Icon | Element | Description |
|---|---|---|
 | Data Model | A specific, versioned, group of data elements. |
 | Data Class | A Structured group of data elements inside a model, and which can be related to another Data Class, by inheritance or containment |
 | Data Element |
...
| An atomic unit of data, sometimes called an attribute, field or property. | ||
 | Data Type | A type or classification descriptor for a data element. Data Types can be sub-typed into enumerations, primitives and measurement units, which get slightly different icons. |
 | Primitive Type | This depends on the model, not needed when model is purely conceptual. |
 | Enumerated Type | This element is composed of a restricted list of enumerations. |
 | Enumeration | This is part of the above Enumerated Type |
 | Measurement Unit | This type is probably based on a primitive, but which represents a common measurement unit. |
 | Business Rules | A.K.A validation rules, these can be attached to elements or to relationships. mostly we use regex or groovy code as a definition, but could be OCL or QVT type constraint. |
 | Assets | These could be imported files, such as csv or XML files describing the model. |
 | Deprecated Item. | Items which are out of date and have been/or will be replaced. |
