Data Modeling Notations

Enterprise Architect supports numerous settings related to data modeling that can influence how database objects are represented on diagrams. These settings, and how they can affect the representation of database objects, are described here.

Stereotype Icons

Access: Design > Diagram > Manage > Properties > Elements : Use Stereotype Icons

Default Value: True

Enterprise Architect provides a diagram-level setting for the display of stereotyped objects. When the checkbox is selected, database objects on the diagram are displayed with an icon representing their stereotype instead of the stereotype name.

 

Stereotype Visibility

Show Data Model Owner

Access: Design > Diagram > Manage > Properties > Elements : Show Data Model Owner

Default Value: True

The system provides a diagram-level setting for the display of Owners. When the checkbox is selected, database objects on the current diagram will be displayed with their full name '{Owner.}ObjectName'.

   

Define Element Characteristics

Show Column Details

Access: Design > Diagram > Manage > Properties > Features : Show Attribute Detail

Default Value: Name Only

The system provides a diagram-level setting for the display of Table column names and datatypes. The available options are: 'Name Only' or 'Name and Type'.

   

Features Tab

Show Involved Column Details

Access: Design > Diagram > Manage > Properties > Features | Show Parameter Detail

Default Value: Type Only

The system provides a diagram-level setting for the display of columns involved in a Table constraint. The available options are: 'None', 'Type Only', 'Name Only' and 'Full Details'.

In these examples, the Primary Key (PK) constraint 'PK_account' involves the column 'accountID'.

Features Tab

Show Column Stereotype

Access: Start > Workspace > Preferences > Objects: Show <<column>> stereotype

Default Value: True

Enterprise Architect provides a global-level setting that controls whether or not the <<column>> stereotype is displayed above each Table's columns. You can therefore hide the stereotype if you prefer, considering that attributes with a stereotype of <<column>> are the only valid option for Tables.

 

Object Display Options

Connector Notation

Access: Design > Diagram > Manage > Properties > Connectors : Connector Notation

Default Value: UML 2.1

Enterprise Architect supports three diagram notations for data modeling:

  • UML 2.1 - the standard UML 2.1 notation for connectors

  • Information Engineering - the Information Engineering (IE) connection style

  • IDEF1X - the Integrated Definition Methods IDEF1X connection style

(These are the same three connectors using the different notations.) The default notation for the Data Modeling diagram is 'Information Engineering', whilst the default notation for models created from Database Engineering Patterns is 'IDEF1X'.
