11.13. Transformation

The transformation information, like with annotations, is projected onto the nodes representing the model objects that are the "output" of the transformation, where the objects that are "inputs" to the transformation are recorded as a (potentially multi-valued) property on the "output" object, and the "transform:transformed" mixin is added to the output node. In other words, virtual base tables, columns, procedures, etc., are marked as "transform:transformed" and have an "input" property pointing to the node(s) that are the inputs for the transformation. The SQL statements, supports flags, and defaults flags are also added as properties on the output virtual base table and procedures, and the "transform:withSql" mixin that defines these properties is added to that output node.
