The parameters in the MDEX Engine query determine the type of top-level object that is returned in response to the query.
You use Presentation API method calls to retrieve and manipulate data from a top-level object and any of its members.
Top-level object types include the following:
Navigation objects contain information about the user’s current location in the dimension hierarchy, and the records that are associated with that location. Navigation objects also contain the information required to build any follow-on queries.
Note
Both navigation queries and record search queries return Navigation objects.
Record object contain full information about individual records in the data set. This information includes the record’s properties, as well as its tagged dimension values.
Aggregated record objects contain information about aggregated records. An aggregated record is a collection of individual records that have been rolled up based on a rollup key (a property or dimension name).
Dimension search objects contain the results of a dimension search.
