# Overview

Conditions and Actions are used extensively in the appRules Integration & Automation Engine.

Examples of usage of Conditions and Actions in workflow activities include:

* **EvaluateConditions** - Evaluates a group of conditions and performs a set of actions based on the result.
* **PerformAction** - Performs the selected action.  A value is returned if the action type is Action Field.
* **PerformActions** - Performs a list of actions.  Conditions can also be entered to indicate the specific actions in the list to be executed.
* **Decision Tables** - The decision rows of decision tables are made up of the conditions to evaluate and the actions to execute if the Conditions evaluate to True.
