This document describes how to use Nested Models with SqlModelMapper. SnapObjects provides an object (SqlModelMapper) that simplifies the usage of nested models in multiple cascading dependent levels. SnapObjects provides APIs to manage the operations performed on these nested models.

Nested Models can represent complex relationships, such as Master-Detail-Detail. The Master-Detail relationship can be of cardinality types: one-to-one and one-to-many. The Master-Detail-Detail relationship can be of cardinality types: one-to-one-to-one and one-to-one-to-many. However, under certain circumstances, you can also manage N-Level relationships for single SQL Insert, Update or Delete operations.
