Go Up to Configuring and Customizing

Diagram and Object Display options affect how the diagram objects appear only for the selected model or submodel. You can choose different display options for each physical and logical model and submodel. By accessing the Diagram and Object Display Options from the Data Lineage Tab, you can also customize the appearance of transformation objects. The diagram and object display options you choose are stored in the.dm1 file along with your diagram and apply only to the current diagram. Diagram display options include setting page boundaries and snapping to grid. Object-specific display options include specifying the information displayed about each object on the diagram. You can specify the content displayed for entities and views. You can also customize display settings for relationships and schema objects.

You can change the entity/table display level to show attributes/columns, primary keys, all keys, tables, definitions or notes. You can also set display options for certain objects to display object datatype, domain, null options, alternate keys, and owner.

For views, you can change the display level to show columns, primary keys, all keys, definitions, and notes. You can also set display options for certain objects to display object owner and parent name.

By default, ER/Studio Data Architect automatically sizes the entities and views to display all the content selected. However, you can manually resize any entity or view by right-clicking the object in the Data Model Window, grabbing a handle, and then dragging to resize the object.

Diagram tab

  • Show Page Boundaries: If selected, displays the page boundaries according to the print options, such as the printer selected, and page size, scale, and orientation chosen in the Print and Print Setup dialogs.
  • Auto-center Diagram over Pages: If Show Page Boundaries has been selected, this option is available. Selecting this option arranges the diagram elements so the diagram always appears centered across the pages required to display or print the diagram.
  • Display and Enable Snap to Grid: If selected, displays grid lines in the diagram background, and align diagram object along their nearest grid line. ER/Studio Data Architect lets you set a grid to the background of your diagram. You can use the grid to align diagram objects and to create a regular or uniform appearance. If you set a grid in the background of your diagram, you can set ER/Studio Data Architect to snap diagram objects to the nearest grid line.
  • Grid Step Size: Specifies the horizontal and vertical size of each grid cell.
  • Grid Steps Per Line: Specifies a horizontal grid spacing per line.
  • Units: Specifies the unit of measurement for grid cells. You can select inches and centimeters.

Entity/Table tab

Display Level: The display level options selected dictate which options will be available in the Available options area.


Warning.gif WARNING: If the Display Level in the Diagram and Object Display Options editor does not match the Attribute Order designation in the Model Options Model > Model Options > Attribute Order, drag and drop errors and on-screen editing errors can occur. If the true attribute sequence, as designated in the Model Options, and the displayed sequence, as designated in the Diagram and Object Display Options, are not synchronized, then ER/Studio Data Architect cannot make the appropriate changes to the entity.

  • Logical Attribute Order: When selected the Primary Key of the table displays at the top. The other columns display in the order designated in the Entity Editor for the corresponding entity.
  • Physical Attribute Ordering: When selected the attributes are ordered by their Column Sequence ID. The sequence ID of a column can be changed by moving it up or down in the list of columns on the Columns tab of the Table Editor.
  • Definition: If selected, displays the entity or table definition as defined on the Definition tab of the Entity Editor or Table Editor.
  • Note: If selected, displays the entity or table note as defined on the Notes tab of the Entity Editor or Table Editor.
  • Display Table Names: If selected, displays entity and table names.
  • Display Column Names: If selected, displays the attribute and column names.
  • Hidden Attributes Marker: This option become available when attributes or keys of an entity in a submodel has been hidden. When selected, an ellipsis displays in submodel entities where all attributes are not currently displayed. Attributes or keys of an entity can be hidden by deselecting the object on the Attributes tab of the Submodel Editor.

  • Note: If selected, displays the view note as defined on the Notes tab of the View Editor.

Transformation tab

Notepad blue icon 2.pngNote: Available only if the Data Lineage tab is active when View > Diagram and Object Display Options is chosen.

Transformation display options control the information displayed for transformation objects in a data flow on the Data Lineage window.
