A CompositeTable object has the same properties as the Table object (see Table Properties), except some that are not applicable to composite tables and thus hidden. There is also a AllowMultipleConnections property specific to CompositeTable (see How Composite Table Data is Fetched, Stored and Updated).
Business logic code can be associated with a composite table as well as with a simple table, in the form of event handlers of a C1TableLogic component (see Table Business Logic Events).
