Creating a column
You can add columns to your tables to represent attributes. A column is derived from the dictionary link between a table and the column.
To create a column through a table relationships diagram:
1. On the Table Relationships Diagram toolbar, click the Column button.
2. On the Table Relationships Diagram, click the Table for which you want to create the Column.
To add a column to a table through a Modeler pane:
In the Modeler pane, right-click the Table for which you want to create a column, point to New, and then click Column.
A new column is added to the table. The name of a column must be unique within the table.
