.. /tutorial/model-tree-structures.txt is just a composite page that
   includes all the tree structure pages for easy overview.

The following documents provide overviews of various data modeling
patterns and common schema design considerations:

.. class:: toc

   :doc:`/applications/data-models-relationships`
      Examples for modeling relationships between documents.

      :doc:`/tutorial/model-embedded-one-to-one-relationships-between-documents`
         Presents a data model that uses :ref:`embedded documents
         <data-modeling-embedding>` to describe one-to-one relationships
         between connected data.

      :doc:`/tutorial/model-embedded-one-to-many-relationships-between-documents`
         Presents a data model that uses :ref:`embedded documents
         <data-modeling-embedding>` to describe one-to-many
         relationships between connected data.

      :doc:`/tutorial/model-referenced-one-to-many-relationships-between-documents`
         Presents a data model that uses :ref:`references
         <data-modeling-referencing>` to describe one-to-many
         relationships between documents.

   :doc:`/applications/data-models-tree-structures`
      Examples for modeling tree structures.

      :doc:`/tutorial/model-tree-structures-with-parent-references`
         Presents a data model that organizes documents in a tree-like
         structure by storing :ref:`references
         <data-modeling-referencing>` to "parent" nodes in "child"
         nodes.

      :doc:`/tutorial/model-tree-structures-with-child-references`
         Presents a data model that organizes documents in a tree-like
         structure by storing :ref:`references
         <data-modeling-referencing>` to "child" nodes in "parent"
         nodes.

      See :doc:`/applications/data-models-tree-structures` for additional
      examples of data models for tree structures.

   :doc:`/applications/data-models-applications`
      Examples for models for specific application contexts.

      :doc:`/tutorial/model-data-for-atomic-operations`
         Illustrates how embedding fields related to an atomic update
         within the same document ensures that the fields are in sync.

      :doc:`/tutorial/model-data-for-keyword-search`
         Describes one method for supporting keyword search by storing
         keywords in an array in the same document as the text field.
         Combined with a multi-key index, this pattern can support
         application's keyword search operations.
