8.3.2.1 Adding a Table

The tools in the vertical toolbar on the left of the EER Diagram tab are used for designing an EER diagram. Start by creating a table using the table tool. The table tool is the rectangular grid in the middle of the vertical toolbar. Mousing over it shows the message, Place a New Table (T).

Clicking this tool changes the mouse pointer to a hand with a rectangular grid. Create a table on the canvas by clicking anywhere on the EER Diagram grid.

Right-click the table and choose Edit in New Window from the pop-up menu. This opens the table editor, docked at the bottom of the application.

The table name defaults to table1. Change the name by entering invoice into the Name: field. Changes here affect the name of the tab in the table editor and the name of the table on the canvas.

Pressing Tab or Enter while the cursor is in the table name field selects the Columns tab of the table editor and creates a default column named idinvoice.

Pressing Tab or Enter again sets the focus on the Datatype list with INT selected. Notice that a field has been added to the table on the EER canvas.

Pressing Tab yet again and the focus shifts to adding a second column. Add a Description and a Customer_id column. When you are finished, close the table editor, by clicking the x button on the top left of the table editor.
