+# Functions
+
+Use built-in functions for data manipulation and analysis to operate on the underlying database storing the chain data. These functions are useful for operations like [`DataChain.filter`](datachain.md#datachain.lib.dc.DataChain.filter) and [`DataChain.mutate`](datachain.md#datachain.lib.dc.DataChain.mutate). Import these functions from `datachain.func`.
