A method may include generating a first user interface for providing, to a client, a first selection of inputs for attributes of a rule scenario for defining a rule. The rule may be applied to modify a data processing functionality of the application. Parameters of the rule may be determined based on the rule scenario and a first input from the first selection of inputs being selected via the first user interface. The parameters of the rule may correspond to data objects affected by the application of the rule. A second user interface for providing, to the client, a second selection of inputs for defining a condition of the rule may be generated. The condition of the rule may evaluate the parameters of the rule. The rule may be generated based on a second input from the second selection of inputs being selected via the second user interface.
