A retail analyst is learning how Microsoft Dataverse organises the data their loyalty app uses. In Dataverse, what is the structure that holds a set of rows and columns, where each column is designed to store a certain type of data?

  • AA table, which is a set of rows and columns that models business data Correct
  • BA business rule, which validates entered data across the columns it covers
  • CA solution, which packages the components that makers build and ship
  • DA dataflow, which transforms source data on its way into the store
In Dataverse, data is stored in tables made up of rows and columns, with each column holding one specific type of data. The grounding defines a table as a set of rows (records) and columns (fields), with each column designed to store a certain type of data such as name, age or salary; tables are how Dataverse organises stored business data.

Why A is correct: Correct. The grounding defines a table as a set of rows (records) and columns (fields), with each column designed to store a certain type of data such as name, age or salary; tables are how Dataverse organises stored business data.

Why B is wrong: A business rule is real Dataverse logic for validation, but the grounding describes it as server-side logic applied to a table, not the structure that stores the rows and columns themselves.

Why C is wrong: Solutions are a genuine Power Platform construct referenced in the grounding for importing definitions, but they package components for deployment rather than store the rows and columns of business data.

Why D is wrong: Power Query dataflows do bring data into Dataverse per the grounding, but they are an import mechanism and not the structure that holds the stored rows and columns.
