Validation

The plausibility check, even plausibility check or plausibility, is a method under which a value or generally a result flashover moderately checked to see if it can ever be plausible, so acceptable, reasonable and understandable or not.

It can not always be verified the accuracy of the value or result, but it is an optional obvious mistake be detected. One advantage of the plausibility check is that they can be performed with only minimal effort, a disadvantage is that less obvious inaccuracies in their frames are not recognized.

Plausibility checks can be carried out easily partly based on already existing knowledge.

Examples

Average age

A calculation of the average age of people in Somewhere would the value of 117 years. The fact that this value can only be incorrect, needs no discussion and no further appeal. The value is not plausible and can be described as wrong.

Right

May As for the estimate of the required time required of a supervisor under § 287 Code of Civil Procedure ( ZPO) regularly the detection of all and also smaller periods can not be required, may and the trial judge must rather with the statement of the charges and a plausibility test content and (in the OLG Schleswig, decision of 22 August 1997 - 2 Wireless 62/97, FamRZ 1998, 185).

Physicians' associations

The elected by a meeting of the physicians' association plausibility Committee shall first check the accounts of the individual physicians if there is evidence for an implausible statement.

Implausibility is assumed when the working day to more than 2 working days each more than 12 hours per contract physician / therapist and / or the quarter of working time is more than 780 hours per contract physician / therapist.

The accounts of Authorized regarded as striking ( implausible ) when billed at more than 2 working days, more than 12 hours each and / or the quarter of working time is more than 156 hours.

Computer area

Plausibility checks are executed both in hardware as in software. Plausibility checks in hardware limited nature of the monitoring, for example of signals that may occur only in specific combinations and sequences. It can transmit measured values ​​to their ( plausible ) range of values ​​and their temporal course be tested.

In software engineering called plausibility of a variable, whether it belongs to a particular data type or is within a predetermined range of values ​​or a specified set of values ​​. It is an important aspect of quality assurance, to ensure that an implemented program meets the pre-established requirements. In this sense, plausibility is also referred to as validation or sanity check.

Plausibility rule

A plausibility rule is a business rule that must be met if an application's data software are (as credible) as plausible and are intended to be further processed. Plausibility rules are often expressed as a formula and describe the permissible limits, the ratio of related data to each other or the like.

Example ( for every single person to apply ):

Enrollment year> = year (date of birth ) 5

As a rule, they are called because they often apply only under certain conditions.

Plausibility rules for data collection

The data acquisition programs for database applications automatically check usually a variety of plausibility rules. This should help to increase the quality of data significantly. If newly acquired or changed data are not valid, it will be either rejected or only with an " Invalid " marking for later correction in the database.

Depending on the software technology, these rules are incorporated either by the programmer in the code or read from a flexible program until runtime and interpreted.

Plausibility of statistical data

A special form are rules for checking and improving the quality of merged from different sources, summarized data in the statistics or in a data warehouse.

Examples ( individual for each product type should apply ):

Production Import Export = Konsumption

Or

Own production Shopping = personal consumption sale

In a " plausibility " mentioned operation, the acquired data will be partly automatically and partly manually checked for plausibility and corrected if necessary.
