Selecting a Data Modeling Strategy

The following DataModel configurations are available. See Parsing Hierarchical Data for examples of querying the data in the different configurations.

  • Document

    Returns a single table representing a row for each document. In this data model, any nested documents will not be flattened and will be returned as aggregates.

  • FlattenedDocuments

    Returns a single table representing a JOIN of the parent and nested documents. In this data model, nested documents will act in the same manner as a SQL JOIN. Additionally, nested sibling documents (nested documents at same height), will be treated as a SQL CROSS JOIN. The add-in will identify the nested documents available by parsing the returned document.

  • Relational

    Returns multiple tables, one for each nested document (including the parent document) in the document. In this data model, any nested documents will be returned as relational tables that contain a primary key and a foreign key that links to the parent table.
