In System Modeler it is not compulsory to use data dictionaries. Existing data dictionaries are migrated to System Modeler as Dictionaries, containing attributes Primitive types.
Similarly to EA Developer, these Primitive types are shared throughout the model or business segment in order to keep them standardized and allow for global updates. Global types are overridden if the attribute is given a new definition at the local level.
On migration, existing data dictionaries takes the following form:
Global – The Global Data Dictionary is renamed as a dictionary called “Dictionary” at the model level.
Local – The Local Data Dictionary is renamed as a dictionary called “Dictionary” at the segment level.
Any new dictionary you create within the model or business segment can be named anything meaningful to your project. Migrated dictionaries can also be renamed.
Value Logic for all dictionary items is migrated to the new system, as are properties such as Primitive (Type) Length, Decimal, and Initial Value.
Data items defined as SameAs data dictionary items in your existing model are migrated as instances of dictionary types so they automatically derive the properties of the Primitive type.
