Table and Schema Methods

The following methods allow the creation and editing of named Schema objects.

Previous versions of SIS used Named Tables to view data from a database table, with rows in the table being linked to graphical items by Item properties.

SIS now uses named Schema objects to control the display of data-oriented parts of the user interface, e.g. the Table Window.

See SIS_OT_SCHEMA for further details.
