Verifier

Overview

• Verification Classification (Group of verifier)
• Verification Type (identification of verifier + name + description for single verifier)
• Verifier (Concrete implementation)

DRD Modeling Level Verification

• Classification: DrdModelingLevelVerification

Lonely Data Input Verification

• Type: LonelyDataInputVerification
• Verifier: LonelyDataInputVerifier

Description

Detection input data nodes, which has no connection to at least one decision table.

Algorithm

doVerification (Definition d) {
    define rL as ResultList
    for each (InputNode i in d.getInputNodes()) {
        if (i.hasNoConnectedDecisionNodes()) {
            add i to rL
        }
    }
    return rL
}

Missing Input Data Verification

• Type: MissingInputDataVerification
• Verifier: MissingInputDataVerifier

Description

Detecting columns which has no reference to either a input node or a decision node with a corresponding output column.

Algorithm

TODO

Missing Input Column Verification

• Type: MissingInputColumnVerification
• Verifier: MissingInputColumnVerifier

Description

Detecting for all decisions and input data nodes if their output names are found in the corresponding input columns of the connected decision.

Algorithm

TODO

Multiple Input Data Verification

• Type: MultipleInputDataVerification
• Verifier: MultipleInputDataVerifier

Description

Detecting columns which has more than one input data (or output columns from decisions).

Algorithm

TODO

Modeling Level Verification

• Classification: ModelingLevelVerification

Predefined Existing Value Verification

• Type: PredefinedExistingValueVerification
• Verifier: PredefinedExistingValueVerifier

Description

Detecting string values, which are not defined in list of predefined values of the column.

Algorithm

TODO

Predefined Missing Value Verification

• Type: PredefinedMissingValueVerification
• Verifier: PredefinedMissingValueVerifier

Description

Detecting predefined string values of a column, which itself are not used in the column.

Algorithm

TODO

Missing Input Value Verification

• Type: MissingInputValueVerification
• Verifier: MissingInputValueVerifier

Description

Detecting output values of output columns in decision tables which are not used in the connected decision table as input values.

Algorithm

TODO

Missing Output Value Verification

• Type: MissingOutputValueVerification
• Verifier: MissingOutputValueVerifier

Description

Detecting input values of input columns in decision tables which are not defined in the connected decision table as output values.

Algorithm

TODO

Empty Output Verification

• Type: EmptyOutputVerification
• Verifier: EmptyOutputVerifier

Description

Detection rules with an empty output values."

Algorithm

TODO

Decision Logic Level Verification

• Classification: DecisionLogicLevelVerification

Subsumption Verification

• Type: SubsumptionVerification
• Verifier: SubsumptionVerifier

Description

Detecting individual rules which are subsumed by other rules, i.e. they are not necessary. For example, rules containing wildcards often render more specific rules unnecessary due to subsumption.

Algorithm

TODO

Partial Reduction Verification

• Type: PartialReductionVerification
• Verifier: PartialReductionVerifier

Description

Checking whether ranges can be combined to simplify decision tables.

Algorithm

TODO

Overlapping Verification

• Type: OverlappingVerification
• Verifier: OverlappingVerifier

Description

Detecting whether there are any overlaps in rule conditions. This verifier does not show identical, overlaps or subsumptions.

Algorithm

TODO

Missing Rule Verification

• Type: MissingRuleVerification
• Verifier: MissingRuleVerifier

Description

Detecting whether there are any missing business rules, i.e. if there are rules missing for expected inputs.

Algorithm

TODO

Identical Rule Verification

• Type: IdenticalRuleVerification
• Verifier: IdenticalRuleVerifier

Description
