You can edit the basic data model in the following ways:
Add and remove rows (a row represents
an object in the data model)
Add, remove, and rename columns (a column
represents a property of the objects in the data model)
Change cell values (a cell represents
a property of a specific object)
Remove all objects
Restore the data model to its initial
state
Paste data from the clipboard
For example, you could remove the x and y columns if
you do not want an X/Y Diagram. You can create a Layout Diagram without
any specific layout attributes.
To delete all the data values, click Remove All Rows. To retrieve the values you saw
initially, click Reset to Default.
Properties id, tag, from and to are mandatory for the SDM model and therefore
cannot be removed or renamed by the user.
Paste from Clipboard replaces the contents of the current table by the information present
in the clipboard. It asks whether you want the column names to be
named based on the first row. If so, the first line of data is used
to give the column names. If not, the column names are named as A,
B, C, and so on, and you can rename them later.
