Data Model Examples and Patterns

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

• Model Relationships Between Documents

• Examples for modeling relationships between documents.

  • Model One-to-One Relationships with Embedded Documents
  • Presents a data model that uses embedded documents to describe one-to-one relationshipsbetween connected data.
  • Model One-to-Many Relationships with Embedded Documents
  • Presents a data model that uses embedded documents to describe one-to-manyrelationships between connected data.
  • Model One-to-Many Relationships with Document References
  • Presents a data model that uses references to describe one-to-manyrelationships between documents.
• Model Tree Structures

• Examples for modeling tree structures.

  • Model Tree Structures with Parent References
  • Presents a data model that organizes documents in a tree-likestructure by storing references to “parent” nodes in “child”nodes.
  • Model Tree Structures with Child References
  • Presents a data model that organizes documents in a tree-likestructure by storing references to “child” nodes in “parent”nodes.See Model Tree Structures for additionalexamples of data models for tree structures.

• Model Specific Application Contexts

• Examples for models for specific application contexts.

  • Model Data for Atomic Operations
  • Illustrates how embedding fields related to an atomic updatewithin the same document ensures that the fields are in sync.
  • Model Data to Support Keyword Search
  • Describes one method for supporting keyword search by storingkeywords in an array in the same document as the text field.Combined with a multi-key index, this pattern can supportapplication’s keyword search operations.
