# Filter Functions (DAX)

The filter and value functions in DAX are some of the most complex and powerful, and differ greatly from Excel functions. The lookup functions work by using tables and relationships, like a database. The filtering functions let you manipulate data context to create dynamic calculations. For a discussion of context, see Context in DAX Formulas.
