What is the purpose of the EVALUATE statement in DAX?

The purpose of the EVALUATE statement in DAX is to display results of a query. When using EVALUATE, it allows users to return a table expression that can be queried within a DAX query context. This means that the EVALUATE statement is primarily utilized to fetch and display data from a specific table or result of a calculation.

In essence, it acts as a way to run a query and output its results, enabling users to view and manipulate the data returned. This is particularly useful for developers and analysts who work with DAX queries in tools like SQL Server Analysis Services or other environments supporting DAX.

Other options relate to different functionalities within DAX or data modeling. While they are important aspects of working with data, they do not accurately represent the specific role of the EVALUATE statement. For example, avoiding data duplication concerns data integrity and modeling, which is not directly tied to the EVALUATE statement's function. Similarly, modifying data model relationships and summarizing data into reports address broader modeling and reporting tasks, rather than the specific purpose of EVALUATE.
