You can use “File | Save” menu to invoke the “Save Diagram As” dialog box. The dialog box allows users to either save the diagram in the internal file format, or export the diagram to a GIF, JPG, SVG or PNG format image file.
The diagram file saved in the internal format holds the table and relationship definitions and also has a reference to the databases defined in the SQL Edge environment. When the diagram is opened, it will be automatically refreshed with the up-to-date table and relationship definitions.
You can also send the diagram file to a colleague. Even if his copy of SQL Edge does not have the same database definitions, he can still open the diagram but in a restricted mode. Except not be able to add or modify relationships among the tables in the diagram, he can still modify other aspects of the diagram and print or save the modified diagram.
