Answer 2

Use DAX only in Data model of Excel Power Pivot.

Whereas SQL is operated as database queries by most programming languages like PHP, Java, C etc.

Answer 3

SQL is relational database, however XML is not database,

XML is used in define document hierarchy and it's useful in document exchange, for example, transfer or interchange a document or database from one format to the other.

XML also good in storing small smount of data like system configuration or document templates.
